Is Rain-X Safe for Your Vehicle’s Windshield

Tue, 28 Apr 2026 18:51:32 GMT

The view through your windshield is the most important screen you will look at all day. When the clouds open up and the rain starts pouring down, that view can get blurry fast. Many drivers turn to specialized glass treatments like Rain-X to help water bead up and fly away. It is a product that has been around for decades, and you can find it in almost every auto parts store in the country. However, as an auto repair shop that deals with glass clarity and safety sensors every single day, we often get asked if these chemical treatments are actually good for your car in the long run.

At Morin Brothers Automotive in San Luis Obispo, CA, we believe in keeping things simple and honest. The short answer is that these products are generally very safe and effective, but they are not a magic fix that you can just apply and forget. There are a few things you should know about how they interact with your wipers, your sensors, and the glass itself to make sure you are actually improving your safety rather than creating a new set of problems.

How These Treatments Actually Work

To understand if a product is safe, it helps to know what it is doing to your vehicle. On a microscopic level, your windshield is not actually a perfectly smooth surface. It is full of tiny peaks and valleys that are invisible to the naked eye. When it rains, water fills these little craters and clings to the surface, creating a sheet of liquid that distorts your vision.

Glass treatments use hydrophobic polymers or silicones to fill in those microscopic holes. This creates a surface that is incredibly slick and level. Because the water cannot find anything to hold onto, it forms tight little beads that the wind simply pushes off the glass once you hit highway speeds. It is a clever bit of chemistry that has saved many drivers from a stressful commute.

The Benefits of a Clearer View

There are some undeniable advantages to using a high-quality glass treatment. When applied correctly, it can drastically change how you experience bad weather.

Better Night Visibility: Rain at night is particularly difficult because of the glare from oncoming headlights. A treated windshield keeps the water moving, which reduces the starburst effect from other cars and helps you see lane markings more clearly.

Easier Cleaning: Because the treatment creates a non-stick barrier, things like bird droppings, squashed bugs, and tree sap have a much harder time bonding to the glass. You will find that your regular car wash does a much better job of getting the windshield spotless.

Winter Assistance: During the cold months, a treated windshield is much easier to scrape. The slick surface prevents ice and frost from anchoring themselves to the glass, so you can spend less time in the freezing cold with your ice scraper.

Potential Issues to Watch Out For

While the chemicals are safe for the glass, there are some side effects that can be a bit annoying if you are not prepared for them. One of the biggest complaints we hear is about wiper chatter. Because the treatment makes the glass so slick, your rubber wiper blades might start to skip or bounce across the surface instead of gliding. This creates a distracting noise and can leave streaks behind.

Another concern is hazing. If you apply too much product or do not buff it out thoroughly, it can leave a greasy film. This film might be invisible during the day, but as soon as a set of headlights hits your windshield at night, it can create a foggy glow that makes it hard to see. This is why the application process is so critical. You have to start with a glass surface that is surgically clean and apply the product in a cool, shaded area to prevent it from drying too quickly.

The Impact on Modern Safety Systems

This is the area where we want you to be the most careful. Many cars built in the last few years have cameras and sensors mounted directly against the inside of the windshield. These systems handle things like automatic emergency braking and lane departure warnings. They are precision-tuned to look through the glass.

If a glass treatment is applied unevenly or starts to wear off in patches right in front of the camera lens, it can confuse the computer. While we have not seen many cases of these systems failing entirely due to a glass treatment, it is always a good idea to keep the area in front of those sensors as clean as possible. If you notice your safety warnings acting up after a DIY glass treatment, that might be the culprit.

Maintain a Clear Outlook

Do not let a rainy forecast fill you with anxiety. Bring your vehicle to Morin Brothers Automotive today and let us give your glass, wipers, and sensors a thorough inspection. We will make sure your view of the road is crystal clear so you can drive with confidence, no matter what the weather decides to do.

8 Features Drivers Forget Their Cars Have

Fri, 27 Mar 2026 12:37:39 GMT

Most drivers learn the big stuff quickly. They know the pedals, the lights, the wipers, and where the gas goes. Then the rest of the car fades into the background. Months or years later, plenty of owners are still driving around with useful features they rarely touch, forgot existed, or never understood in the first place.

That does not mean the car is too complicated. It usually means nobody ever showed them what was there.

Why These Features Get Overlooked

A lot of useful features are easy to miss because they do not come up every day. Some only help in bad weather. Some are tucked into the dash menu. Others are so small and simple that drivers stop noticing them after the first week of ownership. Then a customer comes in for an inspection or a routine service visit, and it turns out the car has been offering a helpful feature the whole time.

Not every vehicle has every one of these, but most modern cars have at least a few of them. Once drivers start using them, everyday driving will get easier.

1. The Fuel Door Arrow

On many dashboards, the little arrow next to the fuel icon points to the side of the car where the gas door is. It sounds tiny, but it saves drivers from pulling up to the wrong side of the pump, especially in a newer car or a shared vehicle.

2. Intermittent Wiper Adjustment

A lot of drivers know the wipers have an intermittent setting, but forget they can usually fine-tune the timing. That small adjustment makes a big difference during light rain, mist, or road spray when full-speed wipers feel excessive.

3. Recirculation Mode

This setting helps the cabin cool faster in summer and can help block outside odors, smoke, or heavy traffic fumes. Many drivers leave it alone, even though it can make the A/C work much better in the right conditions.

4. Manual Shift Or Low-Gear Mode

Even on automatics, many vehicles let you hold a lower gear or manually select one. That can help on steep hills, long descents, or slippery roads where better control is more important than letting the transmission do everything automatically.

5. Tire Pressure Display

Some vehicles do more than show a warning light. They let you see the pressure in each tire individually through the information screen. That is useful before a trip, during weather swings, or any time one tire seems to keep dropping faster than the others.

6. Heated Mirrors Tied To The Rear Defroster

Many drivers do not realize that the rear defroster button often clears the side mirrors at the same time. On a cold or damp morning, this can improve visibility much faster than wiping the mirrors by hand.

7. Traction Control Settings

Drivers often know the light exists, but forget there is usually a button that changes how the system responds. Most of the time, it should stay on, but understanding what the setting does helps in snow, mud, or when the car feels different on slick pavement.

8. Rear Seat Pass-Through Or Folding Seat Release

Some sedans and crossovers have a trunk pass-through or seat release that makes carrying longer items much easier. A lot of owners forget it is there until they are trying to fit something awkward through the trunk opening.

The Owner's Manual Is More Useful Than People Think

The owner’s manual usually gets treated like paperwork instead of something worth keeping in the glove box. That is a mistake. It often explains small convenience and safety features that drivers never fully learn during the first week of ownership. The car may have configurable lighting, lock settings, maintenance reminders, and weather-related features the owner has never even looked at.

This is one reason newer cars can feel more complicated than they really are. The features are there, but the driver never gets shown how to use them properly. Taking ten minutes with the manual can clear up a lot.

Some Forgotten Features Are Worth Using

These are not gimmicks. They are the small things that make daily driving a little easier, safer, and less frustrating. Better visibility, more control in weather, easier cargo access, and simple dashboard information all help drivers get more out of the vehicle they already own.

That is part of why regular maintenance visits are useful beyond repairs . A good shop often ends up answering the everyday questions drivers never get around to asking. Sometimes the best feature in the car is one the owner already has and simply forgot to use.

How Do Throttle Body Issues Change How Your Car Drives

Sat, 28 Feb 2026 14:15:00 GMT

A throttle body problem makes the car feel moody. One day it drives fine, then the next morning it hesitates leaving a stoplight or idles oddly at a red light. Because the symptoms come and go, drivers often assume it’s bad fuel or just a cold engine.

The tricky part is that throttle issues can mimic other problems. You might feel a stumble that seems like ignition trouble, or a surge that feels like the transmission is hunting. Knowing what the throttle body does helps you describe the symptom clearly and get it fixed sooner.

What The Throttle Body Controls

The throttle body is the valve that regulates how much air enters the engine. When you press the gas pedal, the throttle plate opens and allows more airflow, which lets the engine make more power. On many modern vehicles, this is electronic throttle control, meaning the pedal tells a motor to move the throttle rather than pulling a cable.

Because it’s an airflow gatekeeper, small changes make a big difference. A sticky plate, a sensor that is reading wrong, or a motor that is slow to respond can throw off how the engine reacts to your foot. The result is often hesitation, odd idle behavior, or a feeling that power delivery is inconsistent.

Carbon Buildup And A Sticky Throttle Plate

Over time, carbon and oily vapor can coat the inside of the throttle body. Even a thin layer can interfere with airflow at idle, where the opening is small. That can cause a low idle, a high idle, or a hunt where the RPM rises and falls as the engine tries to compensate.

Some drivers notice it most when coming to a stop. The engine may dip too low, feel like it wants to stall, then catch itself. We see this often on vehicles that do lots of short trips because the buildup tends to accumulate faster when the engine rarely gets a long, hot drive.

Hesitation, Flat Spots, And Sluggish Takeoff

A common throttle-related complaint is hesitation right off the line. You press the pedal, there’s a delay, then the car finally responds. That can happen when the throttle plate is sticking, or when the system is not agreeing on how much to open based on sensor input.

A flat spot during light acceleration is another clue. It may feel like the engine is holding back for a moment, then waking up. If you notice the symptom more when the A/C is on or when the engine is under load, it can point toward the throttle system struggling to keep airflow and fuel balanced.

Surging, Stalling, And Rough Starts

Some throttle issues show up as surging at steady speeds. You hold the pedal in one spot, but the car subtly speeds up and slows down, almost like you’re nudging the gas without meaning to. That can happen when the throttle is hunting for the right position, or when airflow control is unstable.

Stalling can happen, too, especially when you shift into gear or come to a quick stop. A rough start that clears up after a few seconds can also be tied to airflow control, particularly if the throttle plate is not returning to its expected resting position. These symptoms are easy to confuse with fuel problems, which is why patterns matter.

Warning Lights And Driveability Changes

When the throttle system is unhappy, you may see a check engine light or a reduced power message on the dashboard. Electronic throttle control has built-in safety logic, so if it sees a mismatch between pedal input, throttle position, and airflow expectations, it may limit response to protect the vehicle. That can feel like the car won’t accelerate the way it should, even though the engine is running.

You might also notice harsher shifts or odd shifting timing. That’s not always a transmission problem. The transmission relies on engine torque data, and if airflow control is inconsistent, the whole drivetrain can feel less predictable than usual.

What Usually Fixes It And What To Avoid

Sometimes the fix is a proper throttle body cleaning, and sometimes parts need replacement if a sensor or motor is failing. The key is doing it correctly, because some throttle bodies need a relearn procedure afterward, so idle and throttle response return to normal. Spraying random cleaner into the intake without knowing what you’re doing can create new issues, especially on electronic throttle systems.

A quick inspection can confirm whether the throttle body is simply dirty, whether there is a related vacuum leak, or whether the issue is coming from a failing component in the throttle circuit. Staying consistent with regular maintenance helps too, because addressing airflow and filter issues early can reduce buildup and keep the system reacting the way it should.

What Happens If You Skip the Engine Oil Change For Too Long?

Fri, 30 Jan 2026 15:00:05 GMT

Skipping an oil change usually starts with good intentions. You get busy, the car seems fine, and the reminder sticker feels like a suggestion more than a deadline. Modern engines can be forgiving for a while, so it’s easy to think you can stretch it just this once.

The trouble is that oil does more than lubricate. It carries heat, suspends contaminants, and protects internal surfaces from wear. When it stays in service too long, it slowly loses the ability to do those jobs well.

The result is often gradual damage that you do not notice until the repair bill is no longer small.

What Engine Oil Does Beyond Basic Lubrication

Oil forms a thin protective film between moving parts like bearings, camshafts, and piston rings. That film prevents metal-to-metal contact, which is where heat and wear spike fast. It also helps cool the engine by carrying heat away from hotspots and back to the oil pan where it can dissipate.

Oil also acts like a cleaning agent. It traps soot, fuel residue, moisture, and tiny metal particles so the filter can catch them or the contaminants can stay suspended until the next oil change. When oil gets old, that balancing act breaks down.

How Oil Breaks Down When You Wait Too Long

Heat cycles gradually oxidize oil, which thickens it and reduces its ability to flow quickly at startup. Add short trips to the mix and you can also get moisture buildup because the engine does not stay hot long enough to boil it off. Fuel dilution can happen too, especially with lots of cold starts, and that thins the oil and weakens protection.

Over time, the additives that help oil resist wear and neutralize acids get used up. Once that happens, sludge and varnish can form, and the oil film becomes less stable under load. Even if the car still drives normally, the engine is quietly paying the price.

A Symptom Timeline: What You May Notice As The Damage Builds

Early on, you might notice nothing at all. Then small clues can show up, like a louder valvetrain tick on cold starts, a slightly rough idle, or oil that looks unusually dark and thin when checked. Some drivers notice a faint burning smell after driving, especially if oil is leaking onto a hot surface, though that can happen with fresh oil too.

As the oil continues to degrade, performance can start to feel a little sluggish, and fuel economy may dip. In colder weather, slow oil flow can make startup wear worse, and the engine may sound harsher for longer. Eventually, you may get warning lights related to oil pressure, variable valve timing, or even misfires if sludge starts interfering with oil-controlled components.

At that point, you are no longer talking about a routine service.

Owner Habits That Make Oil Change Delays Worse

The biggest one is assuming the mileage interval is the only thing that matters. Time matters too, because oil ages even if you are not driving much, especially if the trips are short. Another common habit is topping off and thinking that counts as maintenance, but adding a quart does not remove contaminants or restore depleted additives.

Ignoring small oil leaks also shortens the safe window. Leaks can lower oil level, and low oil can aerate, heat up faster, and lose pressure. We’ve also seen engines where the wrong oil viscosity or a low-quality filter made an extended interval much riskier than the owner expected.

Stretching intervals tends to work best only when everything else is also in good shape.

What Parts Get Hurt First When Oil Is Overdue

Oil-related damage usually starts in places where clearances are tight and oil passages are small. Variable valve timing systems rely on clean oil and consistent pressure, so sludge can cause timing-related codes, rough running, or hesitation. Turbochargers, when equipped, are also sensitive because they spin fast and rely on a steady oil supply.

Bearings can wear as the oil film weakens, and that can lead to low oil pressure over time. Piston rings can stick if varnish builds up, which increases oil consumption and blow-by. Once those issues start, the engine may still run, but it tends to run less efficiently and with more wear every mile.

The scary part is that these failures often feel mild until they are not.

What To Fix Now Vs What Can Wait

If you are overdue but the engine sounds normal, the first step is usually an oil and filter change with the correct oil. That gives you a baseline and a chance to inspect the drained oil for signs of sludge, metal, or fuel dilution. If there are warning lights or unusual noises, the plan may include checking oil level, oil pressure readings, and scanning for timing or misfire codes.

If sludge is suspected, it is important not to jump straight to aggressive flushes without a plan. Sometimes a gentle approach with shorter oil change intervals is safer than trying to dissolve everything at once. In severe cases, deeper inspection may be the smarter move, because sludge can clog oil pickups and starve the engine.

The best plan depends on what the engine is showing you right now.

After The Oil Change

Match oil changes to how you actually drive. Lots of short trips, heavy traffic, towing, or high heat can justify shorter intervals even if you are not hitting high mileage. Check the oil level occasionally, because running low is one of the fastest ways to create damage, and many engines consume some oil as they age.

Pay attention to small changes in sound or idle quality, and do not ignore new leaks. If the vehicle has a maintenance minder, use it as guidance, but remember that real-world conditions vary. Keeping a simple routine is usually cheaper than chasing oil-related problems later.

Consistency is what keeps the inside of the engine clean and protected.

How Often Should You Service Your Car’s A/C?

Fri, 19 Dec 2025 15:45:22 GMT

On a hot day, you probably judge your A/C with one quick test: do the vents blow cold or not? If the air feels reasonably cool, it is easy to assume everything is fine and move on. The truth is, your A/C system can be slowly losing performance long before it quits, and a simple service at the right time can keep you from getting stuck with warm air when you need it most.

Why A/C Service Matters Even When It Still Feels “Okay”

Your A/C system does more than send cold air into the cabin. It controls humidity, clears fog from the windows, and helps you stay focused when the sun is beating down. Inside the system, refrigerant carries oil that lubricates the compressor, and rubber seals rely on that flow to stay healthy.

Over time, small amounts of refrigerant can seep out through hoses and fittings. As the level drops, so does cooling efficiency and lubrication. You may not notice the slow fade right away, but the compressor is working harder than it should. We often see A/C failures that trace back to years of running low on refrigerant with no basic service.

Typical Service Intervals for Car A/C Systems

There is no single mileage number that fits every vehicle, but there are some good guidelines. In general, most modern A/C systems benefit from a professional check every year and a more complete service roughly every 2 to 3 years, assuming no leaks or obvious problems.

An annual check can be as simple as verifying vent temperature, inspecting belts and hoses, checking condenser condition, and making sure the system cycles correctly. The deeper service, performed every few years, usually involves recovering and recharging the refrigerant to the correct level and checking for leaks if performance has dropped.

Climate and Driving Style: What Changes the Schedule

Where and how you drive has a big impact on how hard your A/C works. A vehicle that spends its life in a mild climate at the coast has a very different workload than one baking in inland heat or crawling through city traffic all summer.

If you often drive in high heat, heavy stop-and-go traffic, dusty conditions, or you run the A/C nearly year-round, it makes sense to lean toward shorter intervals. Cars that tow, carry heavy loads, or spend long periods idling also put more demand on the A/C system. When we see vehicles like that in the bay, we talk about inspecting and servicing the A/C system a bit more often than the “average driver.”

Signs You Should Not Wait for a Scheduled Service

Even with a rough schedule in mind, your car’s behavior is the best clue. If you notice any of these changes, it is time to have the system checked sooner rather than later:

The air takes much longer than it used to to get cold
The A/C blows cooler on the highway but warms up at stoplights
You hear clicking, chirping, or grinding when the A/C engages
The system cycles on and off rapidly or the cold air comes and goes
The windshield fogs easily in humid weather even with A/C on

Those are all signs that the system is either low on refrigerant, struggling with a weak component, or dealing with restricted airflow through the condenser or evaporator.

What a Professional A/C Service Actually Includes

A proper A/C service is more than just “adding a can” from the parts store . A professional visit typically includes several steps, such as:

Measuring vent temperatures to see how the system is really performing
Inspecting belts, pulleys, condenser fins, lines, and fittings for damage or leaks
Recovering, measuring, and recharging refrigerant to the exact specified amount
Checking compressor operation, pressures, and cycling behavior
Verifying that blend doors, fans, and controls are sending air where it should go

When we perform this kind of service, we are looking both at how the system is working today and at anything that might cause a sudden failure later in the season.

Common A/C Maintenance Mistakes Owners Make

A lot of A/C trouble comes from well-meant shortcuts. One of the biggest is using do-it-yourself recharge cans over and over without knowing how much refrigerant is actually in the system. Overcharging can be just as harmful as running low. Another is ignoring weak airflow and only focusing on temperature, when a clogged cabin filter or dirty condenser is quietly choking the system.

Running the A/C hard with obvious problems, like strange noises or frequent cycling, can push a stressed compressor over the edge. Our technicians often see units fail that might have been saved with a timely service visit when the first symptoms showed up.

Simple Habits That Help Your A/C Last Longer

You can support regular service with a few easy habits. Replacing the cabin air filter on schedule helps air move freely across the evaporator, which keeps both performance and comfort up. Keeping leaves and debris cleared from the front of the condenser allows better heat transfer.

It also helps to use the system regularly, even in cooler months. Running the A/C on defog settings keeps seals lubricated and moves oil through the compressor. If you notice any change in how quickly the cabin cools, treat that as a small nudge to have things checked instead of waiting for the day the air is no longer cold at all.

If your A/C is taking longer to cool, feels weaker than last summer, or it has simply been a few years since the last proper service, this is a good time to get ahead of it. We can inspect your system, verify refrigerant levels, and make sure every component is doing its job before the real heat arrives.

Why Does My Car's Steering Wheel Vibrate Every Time I Brake? | Morin Brothers Automotive

Fri, 28 Nov 2025 16:15:09 GMT

A steering wheel that shudders under braking is more than an annoyance. It is the front end telling you that something in the brake or suspension system is no longer running true. Left alone, the vibration can grow, wear tires unevenly, and lengthen stopping distances.

Here is how to read the symptoms, what typically causes them, and how to prevent the shake from coming back.

What That Shake Is Telling You

Steering wheel vibration while braking usually points to variations in brake torque at the front wheels. The most common root is rotor thickness variation, not a rotor that literally “warped.”

Uneven pad deposits or a rotor that was clamped with dirty hub faces can create hot and cold spots, so the caliper squeezes harder once per rotation. Play in tie rods, ball joints, or strut mounts then amplifies the feedback you feel in your hands.

Brake and Wheel Issues That Start the Vibration

Rotor thickness variation forms when pads transfer material unevenly, often after repeated hard stops followed by sitting still with the pedal pressed. Rust scale trapped between the rotor hat and hub also tilts the disc slightly, producing lateral runout that becomes thickness variation over time.

Sticking slide pins or a caliper piston that does not retract will overheat one side of the rotor and create a pulsing pedal and shimmy. Bent wheels, uneven tire wear, or a missing wheel weight can stack on top of a minor brake imperfection and make a small shake feel big during stops.

Suspension and Steering Factors That Make It Worse

Even perfect rotors will not feel perfect if the front end has some play. Worn inner or outer tie rods let the wheel toe change as you brake. Aging control arm bushings allow the wheel to shift fore and aft, so the car pulls slightly with pedal pressure and releases when you lift.

Strut mounts and bearings that are dry or damaged let the top of the strut twist unevenly, adding a notchiness to steering as the car slows. In our bays, we often see a light rotor issue paired with one tired bushing or tie rod that, together, create a pronounced shake.

Quick At-Home Checks You Can Do

Verify tire pressures are set at the correct level. A low front tire exaggerates shimmy.

Look across the front tread for cupping or feathering that hints at suspension or alignment problems.

Check wheel faces for fresh scrape marks or bent lips.

After a gentle drive and full cool-down, confirm lug nuts are present and evenly snug. Do not overtighten.

On a safe, empty road, slow from about 55 to 30 mph with light to medium pedal. Note if the shake appears only under braking and whether it comes through the wheel or the seat. Steering shake points forward, seat shake often points rearward.

When To Stop Driving and Get Help

Park and arrange assistance if the brake pedal sinks, the car pulls sharply to one side under braking, you smell burning lining, or the steering wheel oscillates rapidly even with light pedal pressure.

Those signs can indicate a sticking caliper, a hose that has failed internally, or a rotor that has overheated to the point of cracking. Continuing to drive may damage wheel bearings or the ABS tone ring.

How Professionals Separate Rotor Issues from Hardware Problems

Pros measure rather than guess. We map when the shake occurs on a road test, then verify the rotors, hubs, calipers, pads, hoses, and front-end components so the true cause is fixed the first time.

Road test: Note the speed and pedal pressure where the vibration begins and how it changes.
Rotor thickness variation: Use a micrometer at multiple points around each rotor.
Runout checks: Measure hub and rotor lateral runout with a dial indicator.
Correct clamping: Clean the hub face, reinstall the rotor, and torque lug nuts in sequence to spec to rule out distortion.
Caliper function: Free and lubricate slide pins and verify piston retraction.
Pad comparison: Compare left-to-right pad wear patterns for uneven loading.
Hose condition: Inspect flexible brake hoses for internal collapse or damage .
Steering and suspension play: Load-check tie rods, ball joints, control arm bushings, and strut mounts if any play is suspected.
Decision by data: Choose on-car rotor service or parts replacement only after the measurements point to the root cause.

Prevent the Shake from Returning

After fresh rotors and pads, proper bed-in matters. Use several medium stops from moderate speed to transfer a uniform film to the rotor faces. Avoid sitting with the pedal firmly applied after hard stops while the brakes are still hot. Any time wheels are off, make sure the hub faces are cleaned and lugs are torqued with a calibrated wrench, not an impact at full power.

Rotate tires on schedule and keep alignment in spec so cupping does not feed vibration back into the system. A brake fluid exchange at the recommended interval keeps caliper pistons moving freely and helps prevent dragging.

Small Clues That Help Narrow the Source

If vibration is strongest through the steering wheel, the issue is likely at the front axle. If you feel it mostly in the seat, look to the rear. A pulsing pedal with little steering shake often points to rear rotors. A shimmy that also appears when coasting at speed suggests wheel or tire balance in addition to brake torque variation.

What Happens When You Top Off the Wrong Fluid

Tue, 25 Nov 2025 06:24:09 GMT

Adding the wrong fluid can turn a simple maintenance task into an expensive repair. Modern vehicles rely on specific chemistries for lubrication, cooling, hydraulic pressure, and corrosion protection. When a fluid is contaminated or mixed with an incompatible type, seals swell, passages gum up, and sensors give bad readings. If you recently topped off a reservoir and something feels off, it is smart to sort it out before damage spreads.

Why Fluids Are Not Interchangeable

Every fluid in your car has a job and a formula to match. Engine oil carries heat and protects moving parts with a specific viscosity and additive pack. Coolant resists freezing and raises the boiling point while guarding against corrosion. Brake fluid is a hydraulic fluid that must tolerate high heat and absorb moisture without boiling. Transmission and power steering fluids must keep valves and clutches clean while maintaining the correct friction characteristics. Swapping or mixing these chemistries can undo the protection each system needs.

Engine Oil Mix Ups and Additive Clashes

Pouring coolant, washer fluid, or fuel into the oil fill will quickly ruin the oil. Even a small amount of water based fluid breaks the oil film and creates a milky emulsion that cannot protect bearings. Using the wrong oil grade can be harmful, too . Oil that is too thick on cold starts delays lubrication. Oil that is too thin under heat can lower pressure. Additive conflicts can also upset variable valve timing. If the wrong product went into the crankcase, the safest path is to drain it, replace the filter, refill with the exact spec, and recheck after a short run.

Coolant System Contamination

Coolant is not just colored water. It uses specific inhibitors to prevent corrosion in aluminum blocks, radiators, and water pumps. Mixing two different coolant chemistries can cause gel formation or scale deposits that clog small passages. Topping off with plain water dilutes protection and can promote internal rust. The most serious mistake is adding oil, fuel, or transmission fluid to the overflow bottle. Any petroleum in the cooling system attacks hoses and swells rubber seals. In these cases, a full chemical flush and hose inspection are required, and the thermostat and radiator cap should be evaluated as well.

Brake Fluid Is Not ATF or Power Steering Fluid

Brake systems are sealed and rely on DOT rated fluids that are glycol based. They absorb small amounts of moisture safely and maintain a stable boiling point. Power steering and many automatic transmissions use petroleum based fluids. If ATF or steering fluid goes into the brake reservoir, rubber seals can swell and soften, internal passages can gum up, and the master cylinder can fail. Even a small cross fill requires a complete hydraulic flush and often new seals or components. If the pedal feel has changed since the mix-up, stop driving and arrange a tow.

Transmission and Differential Mistakes

Automatic transmissions require the exact fluid type noted on the dipstick or pan label. Friction modifiers inside the fluid control how clutch packs engage. The wrong fluid can cause harsh shifts, flares, or slipping that leaves debris in the valve body. Continuously variable transmissions often use unique fluids that are not compatible with traditional ATF. Gear oil in a differential must match the specified weight and limited-slip additive requirements. If the wrong fluid has been added, an immediate drain and refill with the correct product can prevent a costly internal repair.

Power Steering and Electric Assist Considerations

Hydraulic power steering systems need the correct fluid to protect the pump and rack seals. Some cars use ATF, others use a dedicated steering fluid. Mixing the two can create noise, foaming, and leaks. Many newer vehicles use electric power assist with no fluid at all. In those cases, any fluid found in the reservoir area may be from a separate system. If the assist feels jerky or noisy after a top off, the system should be inspected and bled, and the rack checked for seal damage.

Washer Fluid Where It Does Not Belong

Washer fluid belongs only in the washer reservoir. It contains alcohols and detergents that are not friendly to rubber seals in other systems. If washer fluid went into the coolant bottle, expect a sweet smell and foaming at the cap. If it went into the brake or power steering reservoir, plan on a complete flush and seal inspection. These mixes rarely fix themselves and can worsen with heat.

What To Do Right After a Mix Up

Quick action limits damage. Here is a simple plan that helps in most cases:

Do not start the engine if a major cross-fill is suspected.
Note what was added, about how much, and where.
Bring the vehicle in for a drain, flush, and refill with the correct spec.
Ask for a short test drive and recheck to confirm normal operation.

Bringing the bottle you used helps identify the exact chemistry, which speeds up the fix.

Why Professional Flushing Makes All The Difference

A proper correction does more than drain and fill. The system is cleaned so residue does not continue to circulate. Critical seals are inspected for swelling. Filters or screens are replaced to prevent loosened debris from clogging valves. In cooling systems, the bleed procedure is followed to remove air pockets. In brake systems, each wheel circuit is flushed until fresh fluid runs clear. Skipping these steps is how repeat failures happen.

5 Clues Your Car Has a Hidden Electrical Problem

Fri, 26 Sep 2025 15:00:00 GMT

Modern cars rely heavily on electrical systems. From powering lights and sensors to keeping the engine running smoothly, electricity is involved in nearly every function of your vehicle. When something goes wrong, the signs are not always obvious. A hidden electrical problem can create frustrating issues that seem unrelated at first. Paying attention to subtle clues can help you catch trouble early and prevent larger failures later.

1. Lights That Dim or Flicker

Your headlights, dashboard lights, or interior lamps should stay steady once turned on. If they dim when you accelerate or flicker while driving, the problem may be with the alternator, battery, or wiring. Flickering is often a sign of inconsistent voltage, which can lead to more serious issues if ignored. This clue is one of the easiest ways to spot electrical trouble, and it should never be overlooked.

2. Slow or Hard Starting

When you turn the key or push the start button, the engine should come to life quickly. If it hesitates, cranks slowly, or sometimes fails to start altogether, the cause may be electrical. A weak battery, corroded connections, or a failing starter motor could be at fault. Many drivers mistake this symptom for a bad fuel system, but often the problem lies within the electrical components that provide the spark and power to start the engine.

3. Warning Lights That Don’t Make Sense

The dashboard is designed to alert you when something needs attention. If multiple warning lights appear at once, or if a light comes on without an actual problem being present, it may point to an electrical issue. A failing alternator, a bad ground connection, or faulty sensor wiring can all confuse the vehicle’s computer. Strange warning light behavior is a strong clue that the electrical system deserves a closer look.

4. Power Accessories Acting Up

Electrical systems power more than the engine. Your windows, locks, radio, and climate controls all rely on steady voltage. If windows roll up slowly, the radio cuts out, or the air conditioning switches off unexpectedly, the electrical system may not be providing consistent power. These small annoyances often indicate a larger underlying problem with the wiring or charging system.

5. Battery Problems That Keep Returning

A single dead battery may be nothing more than an old battery reaching the end of its life. But if your battery keeps draining or needing replacement sooner than expected, it’s time to look deeper. The issue might be a parasitic drain, where something continues drawing power when the car is off. It could also be a weak alternator that fails to recharge the battery fully while driving. Recurring battery issues almost always signal electrical trouble that needs professional diagnosis.

It’s Important to Address Electrical Problems Quickly

Unlike mechanical issues, electrical problems get worse, fast, without obvious signs. A small voltage drop today may leave you stranded tomorrow. Because so many systems rely on electricity, ignoring the early clues can lead to breakdowns, damaged components, or even safety hazards. Early diagnosis saves money and prevents inconvenient surprises.

Why Is My Battery Light On While Driving?

Fri, 29 Aug 2025 15:00:00 GMT

Seeing your battery warning light come on while you’re driving can be unsettling. Unlike the check engine light, which could point to many different systems, the battery light focuses on your vehicle’s charging system. It signals that the battery is not being recharged properly by the alternator. While your car may still run for a while on battery power alone, the light serves as an early warning that your electrical system may fail soon if not addressed.

Common Causes Behind the Warning Light

Several issues can trigger the battery light, ranging from simple to serious. A loose or corroded battery connection is often the first culprit. If the wires or terminals are dirty or damaged, the current may not flow efficiently. A worn alternator belt is another frequent cause. This belt drives the alternator, and if it slips or breaks, the alternator can’t generate power. In other cases, the alternator itself may be failing internally. When its output drops, your car relies solely on the battery until it drains completely.

How Electrical System Problems Affect Driving

When the charging system isn’t working properly, you may notice warning signs beyond the dashboard light. Dim headlights, flickering interior lights , or slow power window operation all suggest reduced voltage. If you drive at night with a weak electrical system, your visibility and safety are compromised. A failing charging system can also lead to stalling, since modern engines rely heavily on electronic controls. If the light is on and you start noticing these symptoms, it’s best not to keep driving until the problem is inspected.

Can You Keep Driving With the Battery Light On

Technically, yes, you can continue driving for a short time with the battery light on, but it’s risky. Your car will run on stored battery power alone, which may last anywhere from a few minutes to over an hour, depending on your battery’s health. Once the charge is depleted, the engine will shut off, leaving you stranded. This could happen at an inconvenient or even dangerous time, like in heavy traffic or on a dark road. Treat the light as a sign to get to a safe location and arrange for inspection as soon as possible.

How Mechanics Diagnose Charging System Issues

When you bring your car in for inspection, a technician will start by checking the battery’s condition and charge level. They will then test the alternator output to see if it is generating the correct voltage. Belts and wiring connections are inspected to rule out mechanical issues. In some cases, the technician may also check for parasitic drains, where a component continues to draw power even when the car is off. This process helps pinpoint whether the problem lies with the battery, alternator, or another part of the electrical system.

Preventing Future Battery Light Problems

Routine maintenance is the best way to avoid sudden charging system issues . Regularly checking your battery’s condition can reveal weak cells before they fail. Inspecting the alternator belt during oil changes helps catch wear before it breaks. Cleaning corrosion from battery terminals and tightening connections ensures good conductivity. If your car is older or has high mileage, periodic testing of the alternator and battery during service visits gives peace of mind. Preventive care not only saves you from breakdowns but also extends the life of your charging system components.

Stay Powered and Safe With Morin Brothers Automotive

A battery light is never something to ignore. Even if your car seems to run fine for now, the warning is telling you there’s a problem that needs attention. At Morin Brothers Automotive in San Luis Obispo, CA, we provide expert diagnostics and repairs for batteries, alternators, and charging systems. Our technicians can quickly identify the cause and make sure your car’s electrical system is reliable again. Don’t wait for your vehicle to leave you stranded.

Why Is It Dangerous to Drive With Interior Lights On?

Tue, 29 Jul 2025 11:59:00 GMT

It might seem harmless to leave your car’s interior lights on while driving, especially if you're searching for something or trying to keep kids occupied on a nighttime trip. But while this may feel like a minor convenience, it can actually lead to distractions that reduce your focus and increase your risk of an accident.

Interior lighting is designed primarily for short-term use when the vehicle is stationary. Once you’re on the road, those same lights can interfere with visibility and safety in surprising ways.

How Interior Lights Affect Your Vision

Driving at night already challenges your eyes. Your pupils dilate to adjust to the darkness and focus on what’s ahead. When interior lights are on, especially dome lights or map lights near the windshield, they compete with the darkness outside, reducing your night vision.

This glare from within the cabin causes your pupils to contract, limiting your ability to see the road clearly. Your eyes are forced to adjust between the bright light inside and the dim surroundings outside, which slows your reaction time and may make it harder to notice obstacles, pedestrians, or changes in traffic.

Increased Glare on Windows and Mirrors

Interior lights also reflect off glass surfaces inside the vehicle. If you’ve ever driven at night with a light on and noticed your windshield seemed cloudy or had streaks, you’ve seen this effect. Light bounces off windows and mirrors, creating a glare that can obscure your view of the road.

This is especially dangerous when driving in rain or fog, when outside visibility is already reduced. Reflections from inside the cabin can combine with moisture on the glass to distort your vision even further.

Side and rear-view mirrors are also affected. Bright cabin lights can make it harder to see headlights approaching from behind, making lane changes riskier and reducing overall situational awareness.

Driver Distraction

Interior lights, especially when used for reading, searching, or illuminating activities in the backseat, create distractions. Your attention shifts from the road to whatever is happening inside the vehicle.

If a passenger turns on a light to look at a phone, find something on the floor, or read a book, the change in brightness naturally draws your attention. It only takes a second of distraction to miss a red light, a sudden stop, or a hazard in your lane.

For younger or newer drivers, the temptation to interact with passengers or glance at illuminated objects can be even more dangerous. It’s a scenario where a small choice can have big consequences.

Legal and Safety Considerations

In most areas, it’s not technically illegal to drive with interior lights on. However, that doesn’t mean it’s advised. Law enforcement officers may still pull you over if they believe the lights are affecting your ability to drive safely.

More importantly, if an accident occurs and interior lighting contributes to reduced visibility or distraction, it could impact how fault is determined. In that sense, it’s best to treat this issue as a matter of smart, responsible driving rather than legality alone.

When Interior Lights Are Necessary

There are moments when interior lights might be needed briefly during driving, such as checking a map, locating an essential item, or assisting a child in the back seat. If so, use them only when the vehicle is stopped, such as at a light or in a parking lot.

Many vehicles also come with dimmable lighting, which can help reduce the impact. Some newer models offer ambient lighting that’s subtle enough to use without affecting your night vision. Even in these cases, it’s wise to keep unnecessary lights off while in motion.

What to Do Instead

If you need to locate something while driving at night, your safest option is to pull over. Find a well-lit, safe location and turn on your interior lights without distraction. You’ll be able to see better and avoid the risks that come with split attention.

Encourage passengers not to use interior lights while the vehicle is in motion, unless absolutely necessary. If your vehicle has a rear-seat entertainment system or reading lights, ensure they’re dimmed or angled in a way that doesn’t affect the driver.

Also, make sure your dashboard dimmer is adjusted properly. A dashboard that’s too bright can be just as distracting as a dome light and may reduce your ability to focus on the road.

Can One Mismatched Tire Ruin an AWD Drivetrain?

Fri, 27 Jun 2025 15:00:00 GMT

All-wheel drive (AWD) vehicles are designed for superior traction, better handling, and improved safety on slippery or uneven surfaces. But they rely on a precise balance between all four wheels to function correctly. That’s why tire size, tread depth, and even wear levels need to be consistent across all tires. Replacing just one tire or mixing brands and tread patterns might seem harmless, but for AWD vehicles, it can lead to unexpected and costly issues.

It’s a common question: “Do I need to replace all four tires if only one is damaged?” Let’s find out.

How AWD Systems Rely on Tire Uniformity

Unlike front-wheel or rear-wheel drive vehicles, AWD systems continuously distribute power between all four wheels. They do this through differentials and a transfer case that adjusts torque depending on road conditions and wheel speed. If one wheel is rotating faster or slower than the others because its tire is smaller (even slightly), the system may misinterpret this as slippage.

To compensate, the system works harder to equalize the rotation. Over time, this extra effort creates stress on drivetrain components like the transfer case, center differential, or viscous coupling. These parts are not designed to operate under constant load imbalance and can wear out prematurely.

Tread Depth Discrepancies Can Be Just as Harmful

Even if your tires are the same brand and model, differing tread depths can still create problems. A new tire has deeper tread and a slightly larger overall diameter than a worn tire. This means it will rotate fewer times per mile compared to the worn tires, causing the AWD system to register incorrect wheel speeds.

You might not notice the difference immediately, but over time, your drivetrain components will.

What to Do If You Only Need One New Tire

If one tire is damaged beyond repair and the others are relatively new, your technician may be able to shave the new tire down to match the remaining ones. This process removes some tread from the new tire so it matches the diameter of the others. However, this only works if the difference is small and the other tires still have a substantial amount of tread life left.

In many cases, especially if the existing tires are halfway worn or more, the safest and most cost-effective solution is to replace all four. Although it may be more expensive upfront, it can prevent damage that would be far more costly to repair later on.

The Cost of Ignoring the Problem

If you continue driving with mismatched tires on an AWD vehicle, you could be facing damage to components that aren’t cheap to replace. A failed transfer case or differential repair can run into the thousands. What’s worse, these components don’t usually give much warning before failure. One moment your car drives fine, and the next, you’re stuck on the roadside.

Not only does this impact the performance of your AWD system, but it can also compromise your safety. Uneven tire traction affects handling, especially in wet or icy conditions, where the benefit of AWD should be most noticeable.

Preventive Tips for AWD Tire Maintenance

To avoid running into this issue, make tire rotation a routine part of your vehicle maintenance . Regular rotation helps tires wear evenly, which is especially important for AWD systems. You should also monitor tread depth regularly. If one tire is wearing out faster than the others, it could indicate an alignment issue or other mechanical problem that requires attention.

Stick with the same brand, model, and size when replacing tires, and avoid mixing different types of tires on the same vehicle. Even slight differences in performance or rubber composition can affect how the system reacts.

Is Driving Tired Just as Dangerous as Driving Drunk?

Fri, 30 May 2025 15:00:00 GMT

Falling asleep at the wheel is something most people think will never happen to them, but drowsy driving causes more accidents than you might expect. While drunk driving is widely recognized as a major safety threat, driving while sleep-deprived can be just as dangerous. In fact, studies show that the effects of fatigue can mimic those of alcohol in several key ways.

Knowing the risks of driving tired will help you make smarter choices about when to get behind the wheel and when it’s safer to wait.

How Fatigue Affects Your Ability to Drive

When you’re tired, your brain reacts more slowly. Your attention span shortens, your ability to process information drops, and your decision-making becomes impaired. These are the same effects caused by alcohol, and when combined with long hours on the road, they can become deadly.

Sleep deprivation reduces your awareness of your surroundings, increases the time it takes to brake or swerve, and leads to drifting out of your lane. Even worse, it increases the chances of experiencing “microsleeps”—brief, involuntary lapses in attention that last a few seconds. During a microsleep, your brain essentially shuts down for a moment, and at highway speeds, that can be long enough to cause a serious crash.

Drowsy Driving Is a Common and Underreported Problem

Unlike alcohol or drugs, fatigue doesn’t leave behind a measurable trace like a blood alcohol content reading. That makes it difficult to track in accident reports, but the statistics that do exist are alarming.

According to the National Highway Traffic Safety Administration, drowsy driving contributes to thousands of accidents every year, including many with fatal outcomes. It’s especially common among shift workers, long-haul drivers, and people traveling late at night or early in the morning when natural alertness is at its lowest.

Warning Signs You’re Too Tired to Drive

You may think you can “push through” tiredness, but fatigue isn’t something you can always control with willpower. These are a few signs that it’s time to pull over and rest:

Frequent yawning or blinking
Drifting between lanes
Missing exits or signs
Trouble remembering the last few miles
Heavy eyelids or difficulty keeping your head up

If any of these symptoms start to appear, it’s not worth the risk to keep going.

How Driving Tired Compares to Driving Drunk

Experts often compare 17–19 hours without sleep to having a blood alcohol level of 0.05%. After 24 hours awake, your driving impairment is roughly equal to a 0.10% BAC—which is above the legal limit in all states.

Both types of impairment reduce coordination, slow reaction time, and impact judgment. The key difference is that drowsy drivers may not even realize how impaired they are, making them less likely to pull over and rest.

Simple Ways to Stay Safer on the Road

Getting enough sleep before a long drive is the most effective way to prevent fatigue. Here are a few more tips that help:

Avoid starting long trips late in the day
Plan breaks every 2 hours or 100 miles
Travel with a passenger who can help share the driving
Drink water and stay hydrated
If needed, take a short nap in a safe place

Caffeine can provide a temporary boost, but it’s not a long-term solution. The safest choice is always to rest before continuing.

Can I Get My Car Repaired and Retested After Failing a Smog Check?

Mon, 28 Apr 2025 12:11:00 GMT

Failing a smog check can be frustrating—especially when your vehicle seems to be running just fine. But don't worry, a failed test doesn't mean you're stuck. In most cases, you can have the problem repaired and your vehicle retested, often without much delay. The key is knowing what caused the failure and how to fix it the right way.

If your car didn’t pass inspection, here’s what you should do next.

Understanding Why Your Vehicle Failed

When your car doesn’t pass a smog check, it’s usually due to high emissions, incomplete system readiness, or a malfunction indicated by the check engine light. In California, even minor issues—like a loose gas cap or faulty sensor—can trigger a failure.

Your test results should include a report showing what part of the system didn’t meet standards. This might point to an issue with your catalytic converter, oxygen sensors, evaporative emissions system, or another component. If you’re not sure how to read the report, a qualified repair shop can explain what it means and what needs to be fixed.

Yes—You Can Absolutely Retest

After repairs are made, your vehicle can be retested. In fact, California’s smog program is designed with this process in mind. Many certified test-and-repair stations, including those authorized by the Bureau of Automotive Repair (BAR), offer repair services along with retesting, so you can take care of both steps in one place.

In most cases, your retest will only include the sections you previously failed—so you’re not starting from scratch.

Common Repairs That Help You Pass

Replacing oxygen or air-fuel ratio sensors
Repairing EVAP leaks or faulty purge valves
Replacing a worn catalytic converter
Fixing misfires by replacing spark plugs or coils
Resetting or replacing faulty emission-related sensors

If your check engine light was on during the test, resolving that issue alone may be enough to pass the second time.

Let the System Relearn After Repairs

After repairs are completed, your vehicle may need to complete a few “drive cycles” before it’s ready to retest. This is because the car’s onboard computer system needs time to monitor all systems and confirm the problem is truly resolved.

Depending on your make and model, this may require driving under specific conditions for a certain amount of time. Your repair shop can guide you on whether your car is ready to return for testing.

The Importance of Certified Repairs

To ensure your vehicle passes and that the state recognizes the repairs, it’s best to go to a shop that’s certified to perform smog-related repairs. These shops understand California’s emissions standards and know how to make sure everything is done properly, from diagnostics to final testing.

Even if your car requires a waiver or additional paperwork, a qualified shop can help you through the process smoothly.

At Morin Brothers Automotive in San Luis Obispo, CA, we help drivers who didn’t pass their smog test get back on the road. From emissions diagnostics to certified repairs and retesting, our experienced team will guide you every step of the way.

Can Brake Fluid Go Bad Just Sitting in the Reservoir?

Fri, 28 Mar 2025 16:00:00 GMT

You might not think twice about your brake fluid—until something feels off when you press the pedal. Even if you haven’t touched your brakes or opened the reservoir, brake fluid can still go bad over time just by sitting there. That’s because it absorbs moisture from the air, and once it becomes contaminated, it stops doing its job as effectively.

Brake fluid may not wear out like oil or brake pads, but it does have a shelf life, even inside a sealed system. And when it goes bad, it can compromise your braking performance without warning.

Brake Fluid Has a Limited Life

Brake fluid is hygroscopic, meaning it naturally attracts and absorbs moisture—even in a closed system. Over time, water vapor seeps in through rubber brake hoses and seals. As more moisture builds up in the fluid, its boiling point drops.

Under hard braking, like during a sudden stop or mountain driving, your brake system heats up fast. If the fluid has absorbed too much moisture, it can boil under pressure, forming air bubbles that compress and reduce braking force. That leads to a soft or spongy pedal—and in extreme cases, brake failure.

Even if you’re not pushing your brakes hard, moisture and contaminants inside the fluid can corrode internal components like the master cylinder, ABS valves, and calipers. That’s how old fluid quietly causes expensive damage behind the scenes.

How Long Does Brake Fluid Last

Most manufacturers recommend replacing brake fluid every 2 to 3 years, regardless of mileage. The reason? It’s not about how often you drive but how much moisture the fluid has absorbed over time.

In a dry climate, fluid may last slightly longer. But in more humid regions—like San Luis Obispo, CA, where ocean air and seasonal moisture are common—brake fluid can degrade more quickly. If you haven’t had it tested or replaced in years, it’s probably overdue.

Signs Your Brake Fluid May Be Bad

Unlike oil, brake fluid doesn’t come with a change reminder. So, how do you know it’s gone bad? Some signs include:

A spongy or soft brake pedal
Increased stopping distance
Brake warning lights (often triggered by ABS system issues)
Dirty or dark-colored fluid in the reservoir

Fresh brake fluid is usually light yellow or clear. If yours looks dark brown or murky, it’s a sign of moisture, oxidation, or internal corrosion—and it needs to be flushed out.

Brake Fluid Flush

A brake fluid flush removes the old, contaminated fluid and replaces it with new, moisture-free fluid that restores proper system pressure and pedal feel.

Flushing isn’t just about topping off the reservoir—it involves pushing fresh fluid through the entire brake system to clear out the lines, calipers, and ABS components. It’s a maintenance service that protects both your stopping power and your wallet by avoiding long-term component damage.

Neglecting fluid changes might not cause problems immediately, but over time, it increases the risk of serious brake system failures—especially when you need your brakes most.

Is This Something You Can Check Yourself

You can visually inspect your brake fluid through the reservoir on top of the master cylinder. If the fluid is dark, murky, or below the minimum line, it’s time to have it checked.

However, determining fluid quality accurately requires a brake fluid tester, which checks the moisture content. Our professionals can quickly tell whether your fluid is still good or needs to be replaced.

And if you’ve recently replaced brake pads or rotors, it’s a good idea to check the fluid as well—fresh brakes won’t perform their best if they’re paired with old, water-saturated fluid.

If you’re not sure when your brake fluid was last replaced, bring your car to Morin Brothers Automotive in San Luis Obispo, CA. We’ll test the fluid, inspect your brake system, and perform a full flush if needed—so your brakes respond exactly when you need them to.

Why Is My Car Making A Rattling Noise When I Drive?

Fri, 28 Feb 2025 17:00:00 GMT

A rattling noise while driving can be more than just an annoyance—it could be a warning sign of a developing problem. Whether it’s a loose heat shield, worn suspension components, or something more serious, tracking down the source of the noise early can save you from expensive repairs and potential safety risks. So, what’s causing that unsettling rattle?

Common Causes of Rattling Noises While Driving

Loose Heat Shields
One of the most common causes of a rattling sound under the car is a loose or damaged heat shield. Heat shields protect various components from excessive heat, but over time, they can become corroded or loosened due to vibrations. If you hear a metallic rattling noise, especially when idling or accelerating, a loose heat shield could be the culprit.

Exhaust System Issues
A rattling exhaust could indicate a loose exhaust clamp, a broken hanger, or an issue with the catalytic converter. If the sound gets louder when accelerating or driving over bumps, an exhaust component may be loose or damaged. In some cases, a failing catalytic converter can cause a metallic rattling noise due to broken internal components.

Worn Suspension or Steering Components
If the rattling noise occurs when driving over bumps or rough roads, worn suspension parts such as sway bar links, bushings, or control arms could be to blame. Loose steering components can also create a knocking or rattling noise, which may worsen over time if not addressed.

Loose or Worn Engine Mounts
Engine mounts keep the engine securely in place, but over time, they can wear out or break, leading to excessive engine movement. A failing engine mount can cause a rattling or clunking noise, particularly when accelerating or shifting gears.

Damaged or Loose Interior Components
Sometimes, rattling noises originate from inside the cabin. Loose dashboard panels, door trim, or objects in the glove box or cupholders can create rattling sounds, especially on rough roads. Checking for loose interior items can help rule out minor causes before assuming a mechanical issue.

Tire and Wheel Issues
Rattling sounds from the wheels could be caused by loose lug nuts, worn wheel bearings, or damaged hubcaps. If the sound changes with vehicle speed, it’s worth having your tires and wheels checked for any loose or damaged components.

What to Do If Your Car Is Making a Rattling Noise

If you hear a rattling noise while driving, here are a few steps to help diagnose and address the issue:

Pay attention to when the noise occurs – Does it happen at certain speeds, when accelerating, or when hitting bumps? This can help narrow down the cause.
Check for loose items – Remove any loose objects from the cabin or trunk to rule out minor sources of rattling.
Inspect under the car – Look for loose heat shields, exhaust components, or anything that may be hanging or vibrating.
Listen from different areas – If possible, have someone else drive while you listen for the source of the noise.

If the unusual car sound persists or worsens, it’s best to have it checked by a professional. The experienced team at Morin Brothers Automotive in San Luis Obispo, CA, can diagnose and repair rattling noises to keep your car running safely and quietly .

How Can You Keep Kids Entertained on a Long Drive?

Fri, 31 Jan 2025 16:00:00 GMT

Long drives can be a test of patience for both kids and parents. Between the never-ending “Are we there yet?” questions and restless energy, keeping children entertained is essential for a peaceful trip. Whether you're heading out for a road trip or just tackling a long commute, planning activities in advance can make all the difference.

Pack a Road Trip Activity Bag

A well-stocked activity bag can be a lifesaver when kids start to get bored. Include coloring books, stickers, small puzzles, and a variety of toys to keep them engaged. If your children enjoy reading, pack a few books or audiobooks to give them something to focus on.

For younger kids, interactive toys like magnetic drawing boards or felt playsets can keep their hands busy without making a mess. Older kids might appreciate activity books with mazes, crossword puzzles, or word searches to pass the time.

Make Use of Technology—But in Moderation

Tablets and smartphones can be great tools for entertainment, but they shouldn’t be the only option. Download educational games, movies, or TV shows before the trip to avoid relying on an internet connection. Set time limits to ensure screen time doesn’t take over the entire drive.

To keep things interactive, choose audiobooks or kid-friendly podcasts that the whole family can enjoy. This way, everyone stays entertained without staring at a screen for hours.

Turn the Drive into a Game

Classic road trip games are still some of the best ways to keep kids engaged. Games like “I Spy,” the “Alphabet Game,” or “20 Questions” can be played without any extra materials. You can also try car bingo—print out bingo cards with common road trip sights like stop signs, cows, or construction cones and see who gets bingo first.

Another fun option is a scavenger hunt. Create a list of things kids should look out for, such as different license plates, landmarks, or certain colors of cars. Offering small rewards for completed lists can make the game even more exciting.

Take Frequent Breaks

Sitting in a car for hours can be tough for kids with lots of energy. Plan stops at rest areas, parks, or scenic overlooks where they can stretch their legs and burn off some steam. Letting them run around for a few minutes can make the next stretch of driving more bearable for everyone.

If you're traveling through San Luis Obispo, CA, consider stopping at one of its many beautiful outdoor spots, like a beach or hiking trail, to break up the trip. A little fresh air can go a long way in keeping kids happy.

Bring Plenty of Snacks

Hunger can turn even the happiest child into a cranky passenger. Pack a variety of snacks to keep everyone satisfied. Try to choose options that aren’t too messy, such as granola bars, fruit slices, crackers, or cheese sticks.

To make snack time more fun, consider packing small surprise snack bags with different treats for different points of the drive. Giving kids something to look forward to can help pass the time.

Encourage Storytelling and Creativity

Long drives are a great time to get creative. Ask kids to make up a story one sentence at a time, with each person in the car adding to it. You can also bring along a notebook for them to draw pictures of things they see on the road.

Another option is to create a family road trip journal where kids can write about the places they pass, what they enjoyed about the trip, and any fun moments that happened along the way. This can be a great keepsake to look back on in the future.

Let Kids Help Plan the Trip

Giving kids a sense of involvement can make them more excited about the journey. Before you hit the road, let them help pick out some of the places you’ll stop. If they feel like they have a say in the trip, they’ll be more engaged and less likely to get bored.

Even if they just choose where to eat lunch or which gas station to stop at, having a small role in decision-making can make the drive feel like an adventure instead of just a long ride.

Keeping kids entertained during a long drive doesn’t have to be stressful.

Why Are My Wiper Blades Not Clearing Water Properly?

Fri, 29 Nov 2024 16:00:00 GMT

It’s pouring rain, and you flick on your windshield wipers, expecting a clear view ahead—but instead, streaks, smudges, or even patches of untouched water make it hard to see. Sound familiar? While wiper blades might not seem important to your car, they keep you safe during bad weather. If they’re not working as they should, it’s time to figure out why.

Common Reasons Your Wiper Blades Aren’t Performing Well

If your wipers are leaving water behind or creating a streaky mess, it could be due to one or more common issues. Let’s dig into what might be causing the problem.

Worn or Damaged Blades
Over time, wiper blades take a beating from exposure to sunlight, extreme temperatures, dirt, and grime. The rubber can crack, harden, or tear, which affects how effectively the blades can press against the glass. If your blades look brittle or the edges are uneven, it’s probably time for a replacement.

Dirty Windshield or Wiper Blades
A dirty windshield or blades can cause a lot of trouble. Dust, debris, and road grime create a barrier between the glass and the rubber, making it impossible for the wipers to clear water effectively. In some cases, the dirt can even scratch your windshield, leading to long-term damage.

Incorrect Blade Installation
It’s easier than you might think to install wiper blades incorrectly. If they’re not secured properly or don’t fit snugly against the windshield, they won’t sweep water away efficiently. Always double-check that your blades are the right size and securely in place.

Bent Wiper Arms
The arms holding your wiper blades can sometimes get bent out of shape, especially if you’ve accidentally pulled them up too hard or a strong wind has caught them. A bent arm means the blade can’t maintain even contact with the windshield, leading to missed spots and streaks.

Worn-Out Wiper Motor or Linkage
If your wipers aren’t moving at the right speed or seem sluggish, the problem might not be the blades at all. The wiper motor or linkage could be worn out or malfunctioning, preventing the blades from making full, consistent passes across the windshield.

How to Fix the Problem

Clean Everything Thoroughly
Start with the basics: clean your windshield and wiper blades. Use a glass cleaner and a microfiber cloth to remove dirt and grime from the glass. For the blades, a damp paper towel with a bit of rubbing alcohol can work wonders. Cleaning can often resolve minor issues immediately.

Inspect and Replace Blades if Needed
Take a close look at your wiper blades. If they’re cracked, hardened, or more than six months old, consider replacing them. High-quality blades are worth the investment—they’ll last longer and perform better in all weather conditions.

Check the Wiper Arms
If your blades look fine but aren’t clearing water properly, inspect the wiper arms. Are they bent? Do they look out of alignment? If you notice any issues, a professional can adjust or replace them to restore proper function.

Verify Installation
If you’ve recently changed your wiper blades and they’re not working well, make sure they’re installed correctly. Refer to your vehicle’s manual or consult a professional to ensure everything is in place.

Address Mechanical Problems
If the issue is with the wiper motor or linkage, cleaning and replacing the blades will not help. Unusual noises or erratic wiper movement are signs that you should have a professional look under the hood to diagnose and fix the problem.

What Are the Benefits of Using Synthetic Oil?

Thu, 31 Oct 2024 16:00:00 GMT

Taking care of your vehicle goes beyond washing it regularly and keeping the gas tank full. One of the most important aspects of vehicle maintenance is choosing the right kind of oil. While conventional oil has long been a go-to choice for many drivers, synthetic oil is quickly becoming the preferred option due to its numerous benefits. But what exactly sets synthetic oil apart, and why should you consider it?

What Is Synthetic Oil

Before we jump into the benefits, let’s clarify what synthetic oil actually is. Unlike conventional oil, which is derived from crude oil, synthetic oil is man-made through a chemical process. It’s specifically engineered to provide superior lubrication and performance under various conditions, making it more effective in protecting your engine . Synthetic oil is designed to last longer and perform better, especially in extreme temperatures, which brings us many benefits.

1. Better Performance in Extreme Temperatures

One of the standout advantages of synthetic oil is how it handles both hot and cold temperatures. In cold weather, conventional oil tends to thicken, which can make it harder for your engine to start. Synthetic oil, however, maintains its viscosity, meaning it flows more easily, even in freezing temperatures. On the flip side, during the summer months or when driving in particularly hot climates, synthetic oil resists breaking down, ensuring your engine stays well-lubricated and protected, even under high heat.

This temperature stability means your engine experiences less wear and tear, leading to a longer engine life and fewer breakdowns. So, whether you’re facing a frigid winter or scorching summer heat, synthetic oil has your back.

2. Longer Oil Change Intervals

Nobody enjoys making frequent trips to the shop for an oil change, and with synthetic oil, you won’t have to. One of its biggest selling points is that it lasts longer than conventional oil. Traditional oil typically needs to be changed every 3,000 to 5,000 miles, depending on your driving habits. Synthetic oil, on the other hand, can go anywhere from 7,500 to 10,000 miles or more between changes.

This means fewer oil changes, less time spent in the shop, and ultimately, money saved in the long run. Plus, the extended life of synthetic oil helps reduce waste, making it a more environmentally friendly option.

3. Superior Engine Protection and Wear Reduction

Engines contain moving parts that constantly rub against each other, causing friction. Over time, this friction can lead to wear and tear on your engine, reducing its lifespan. Synthetic oil is specially formulated to provide better lubrication, which reduces friction and protects your engine from damage.

It also leaves fewer deposits on engine components, keeping them cleaner and functioning more efficiently. The reduction in engine sludge buildup ensures that your engine runs smoother for longer, without the risk of overheating or damage. This level of protection can be especially important if you drive in stop-and-go traffic or tow heavy loads, which put extra strain on your engine.

4. Increased Fuel Efficiency

Did you know that using synthetic oil can improve your car’s fuel efficiency? Because synthetic oil is designed to flow more easily through your engine, it reduces the amount of energy your engine needs to use to pump the oil. Less resistance means your engine can operate more efficiently, which in turn helps to improve your vehicle’s fuel economy.

While the fuel savings may not seem dramatic at first, over time, the improved efficiency can add up, saving you money at the pump. For drivers who spend a lot of time on the road, this added fuel efficiency can make a noticeable difference in overall costs.

5. Fewer Emissions and Environmental Benefits

Synthetic oil is often regarded as a more environmentally friendly choice for a few reasons. First, its longer lifespan means you’ll use less oil over time, which reduces oil waste. Second, synthetic oil burns cleaner than conventional oil, producing fewer harmful emissions that contribute to air pollution.

Because synthetic oil reduces engine friction and allows your engine to run more efficiently, it helps decrease the amount of carbon dioxide your vehicle emits. By making the switch to synthetic oil, you’re not just protecting your engine—you’re also doing your part to protect the environment.

Should You Switch to Synthetic Oil

If you’re still wondering whether switching to synthetic oil is worth it, consider the benefits we’ve discussed. With improved engine performance, longer intervals between oil changes, better fuel efficiency, and increased protection against wear and tear, synthetic oil offers a host of advantages that conventional oil simply can’t match. While it may come at a higher upfront cost, the long-term savings and extended engine life can make it a worthwhile investment for most drivers.

Whether you drive long distances every day, live in extreme climates, or just want to protect your engine as much as possible, synthetic oil is a smart choice for keeping your vehicle running smoothly.

Let’s look into the most common causes and why addressing them promptly is important.

Unbalanced Tires

One of the most common reasons for vehicle vibrations at high speeds is unbalanced tires. When the tires are not properly balanced, the weight distribution around the wheel becomes uneven. This imbalance is usually felt through the steering wheel, making the drive uncomfortable and potentially dangerous over time.

Tire imbalance can happen gradually due to normal wear and tear or suddenly after hitting a pothole or curb. This is why regular tire balancing is crucial to maintaining a smooth ride. Ignoring this can lead to uneven tire wear, which only exacerbates the issue and can result in costly repairs down the line.

Worn Suspension Components

Your vehicle’s suspension system plays a crucial role in absorbing the shocks from the road and providing a smooth ride. However, when components like shocks, struts, or bushings wear out, they can lead to vibrations, especially at higher speeds. Worn suspension parts struggle to keep the tires in f irm contact with the road , leading to a bumpy and unstable driving experience.

If you notice that the vibrations are more pronounced when driving over rough roads or at highway speeds, it might be time to have your suspension system inspected. Addressing these issues promptly can prevent further damage and ensure a safer, more comfortable ride.

Wheel Alignment Issues

Proper wheel alignment is essential for smooth and safe driving. Misaligned wheels can cause your vehicle to pull to one side and may also lead to vibrations, particularly at higher speeds. This happens because misaligned wheels create uneven resistance against the road surface, leading to friction and instability.

Wheel alignment can be thrown off by everyday driving conditions, such as hitting a pothole or curb. Regular alignment checks are vital to prevent these vibrations, prolong the life of your tires, and improve overall vehicle handling.

Tire Wear and Damage

Tires are the only part of your vehicle that touches the road, so their condition is critical to a smooth ride. Uneven tire wear is a significant cause of vibrations at high speeds. When your tires wear unevenly, they create an imbalance, leading to a bumpy ride. Common causes of uneven wear include improper tire inflation, misalignment, and neglecting regular tire rotations.

Furthermore, any visible damage to your tires, such as cuts, bubbles, or cracks, can cause vibrations. Driving on damaged tires not only makes your ride uncomfortable but also poses a safety risk, as it increases the likelihood of tire failure. Regularly inspecting your tires and replacing them when necessary is key to maintaining a smooth, safe driving experience.

Brake System Issues

Brake system problems can also cause vibrations , particularly at high speeds. Warped brake rotors are a common issue where the rotor surface becomes uneven due to excessive heat and wear. This uneven surface causes the brake pads to make inconsistent contact with the rotors, leading to vibrations that can be felt even when you're not actively braking.

If you suspect that your brake system is causing vibrations, it's crucial to have it checked immediately. Driving with compromised brakes not only affects your comfort but also your safety, as it can significantly reduce your vehicle's ability to stop effectively.

Drivetrain Problems

The drivetrain, which includes components like the driveshaft, axles, and joints, is responsible for transferring power from the engine to the wheels . If any of these components are worn or damaged, it can lead to vibrations, especially at higher speeds. For example, a worn or damaged universal joint (U-joint) in the driveshaft can cause the vehicle to shake as speed increases.

Drivetrain issues often come with additional symptoms, such as clunking noises or difficulty when turning. If you suspect a drivetrain problem, it’s important to have it inspected and repaired as soon as possible to prevent further damage and ensure a smooth ride.

What Is Traction Control and How Does It Work?

Mon, 29 Jul 2024 12:03:00 GMT

When driving on a slick, rainy road, your tires often struggle for grip, and your car can start sliding at any time. This is where traction control comes in to save the day. Traction control is an essential safety feature in modern vehicles, designed to prevent wheel slip and maintain optimal traction on various driving surfaces. But how does it work?

Vehicle's Traction Control

Traction control is a system integrated into your vehicle's stability control and anti-lock braking system (ABS). Its primary purpose is to monitor the speed of each wheel and prevent them from spinning too quickly when a wheel loses grip and starts to spin faster than the others, traction control steps in to reduce power to that wheel, helping to regain traction and maintain control of the vehicle.

The system utilizes sensors placed on each wheel to continuously monitor their speed. If the sensors detect that one wheel is spinning significantly faster than the others, indicating a loss of traction, the traction control system takes action. This action can involve reducing engine power, applying the brakes to the slipping wheel, or a combination of both. By doing so, the system helps ensure that all wheels maintain equal grip on the road surface.

How Does Traction Control Work?

At its core, traction control works by detecting and correcting wheel slip. Here's a step-by-step breakdown of how the system operates:

Detection
Wheel speed sensors constantly monitor the rotation speed of each wheel. These sensors send data to the vehicle's onboard computer.

Analysis
The onboard computer analyzes the data to determine if any wheel is spinning faster than the others. If it detects a significant speed difference, it interprets this as wheel slip.

Intervention
Once wheel slip is detected, the system intervenes by either reducing engine power or applying the brakes to the slipping wheel. This intervention helps the wheel regain traction.

Correction
By reducing power or braking, the system slows down the spinning wheel, allowing it to regain grip on the road. This process happens in milliseconds, ensuring that the driver maintains control of the vehicle.

Continuous Monitoring
Traction control monitors wheel speeds and adjusts as needed to prevent slip and maintain optimal traction.

Benefits of Traction Control

Traction control offers several significant benefits, making it a crucial safety feature in modern vehicles:

Improved Stability
By preventing wheel slip, traction control helps maintain vehicle stability , especially in slippery or uneven road conditions. This is particularly beneficial during inclement weather, such as rain, snow, or ice.

Enhanced Safety
Traction control reduces the risk of skidding and loss of control, providing an extra layer of safety for drivers and passengers. It helps prevent accidents that could occur due to sudden loss of traction.

Increased Confidence
Knowing that your vehicle is equipped with traction control can give you added confidence when driving in challenging conditions. You can trust that the system will assist in maintaining control, allowing you to focus on driving safely.

When Is Traction Control Most Effective?

Wet or Icy Roads
Traction control shines on wet or icy surfaces where the risk of wheel slip is high. By preventing wheels from spinning excessively, it helps maintain control and reduces the likelihood of skidding.

Gravel or Loose Surfaces
On gravel or loose dirt roads, traction control helps prevent wheel spin, ensuring that your vehicle maintains forward momentum and stability.

Sharp Turns
During sharp turns, especially at higher speeds, traction control helps manage the distribution of power to the wheels, preventing slip and ensuring a smooth, controlled turn.

Common Misconceptions About Traction Control

Despite its benefits, there are some common misconceptions about traction control:

It's Not a Substitute for Safe Driving
Traction control is a helpful tool, but it's not a substitute for cautious and responsible driving. Drivers should still adjust their speed and driving habits according to road conditions.

It Can't Prevent All Accidents
While traction control can significantly reduce the risk of certain types of accidents, it can't prevent all accidents. Drivers should always remain vigilant and avoid relying solely on electronic aids.

It's Not Just for High-Performance Cars
Traction control is a standard feature in many modern vehicles, not just high-performance or luxury cars. It's a valuable safety feature for all types of vehicles and drivers.

Maintaining Your Traction Control System

To ensure your traction control system functions properly, regular maintenance is necessary. Here are some tips to keep it in top condition:

Regular Inspections: Have your vehicle's traction control system inspected during routine maintenance checks . Ensure that wheel speed sensors and other components are functioning correctly.

How Does Tread Depth Affect Vehicle Safety And Stability?

Thu, 30 May 2024 18:00:00 GMT

Have you wondered why those grooves on your tires are so important? Tread depth might seem like a minor detail, but it plays a crucial role in your vehicle's safety and stability. The condition of your tires can be the difference between a smooth, safe ride and a hazardous journey. Learn the importance of tread depth and how it impacts your driving experience.

The Importance of Tread Depth

Tread depth refers to the vertical measurement between the top of the tire tread and the bottom of the tire's deepest grooves. These grooves maintain traction on the road, especially in adverse weather conditions. When your tire treads are deep enough, they help channel water, snow, and debris away from the tire's contact patch, ensuring better grip and control.

Proper tread depth is crucial for effective braking and acceleration. When your tire treads are shallow or worn out, your vehicle's ability to maintain traction decreases significantly. This can lead to longer stopping distances and reduced handling, both of which are major safety concerns. Regularly checking your tire tread depth and ensuring it's within safe limits is an easy yet vital maintenance task.

How Tread Depth Affects Vehicle Safety

One of the most significant ways tread depth affects vehicle safety is through its impact on stopping distance. Tires with sufficient tread depth can effectively grip the road, reducing the distance it takes for your car to come to a complete stop. This is particularly important in wet or icy conditions, where the risk of skidding and hydroplaning increases.

Hydroplaning occurs when a layer of water builds up between the road surface and your tires, causing a loss of traction. Adequate tread depth helps prevent this by channeling water away from the tire, allowing it to maintain contact with the road. Without sufficient tread depth, your vehicle is more likely to hydroplane, leading to a dangerous loss of control.

The condition of the tires also affects your vehicle's handling and stability. Tires with deeper treads provide better traction, improving cornering and overall stability. This is especially important during high-speed driving or when navigating sharp turns. Worn-out tires, on the other hand, can cause your vehicle to feel unsteady and less responsive, increasing the likelihood of accidents.

Legal Requirements and Recommendations

Different regions have specific legal requirements for minimum tread depth. In most places, the minimum legal tread depth for passenger vehicles is 2/32 of an inch. However, the safety experts recommend replacing your tires when the tread depth reaches 4/32 of an inch (about 3.2 millimeters) to maintain optimal safety and performance.

You can use a tread depth gauge or the penny test to measure your tread depth. Insert a penny into the tire tread with Lincoln's head facing down. If you can see the top of Lincoln's head, it's time to replace your tires. Regularly inspecting your tires for uneven wear, cuts, or punctures is also crucial for maintaining vehicle safety.

Tips for Maintaining Optimal Tread Depth

Maintaining optimal tread depth is essential for ensuring vehicle safety and performance. Here are some tips to help you keep your tires in top condition:

Regular Inspections: Check your tire tread depth at least once a month and before long trips. Look for signs of uneven wear, cuts, or punctures.
Rotate Your Tires: Regularly rotating your tires helps ensure even wear and extends their lifespan. Follow your vehicle manufacturer's recommendations for rotation intervals.
Proper Inflation: Keeping your tires properly inflated helps maintain even tread wear and improves fuel efficiency. Check your tire pressure regularly and adjust it according to your vehicle's specifications.

While it may offer increased viscosity, which can provide better protection, using too thick oil can hinder engine performance, particularly in colder temperatures. Sticking to the viscosity recommended by your vehicle's manufacturer is essential to ensure optimal engine function.

Myth #3: Additives Can Prolong Oil Change Intervals

Don't be swayed by products claiming to extend oil change intervals with magical additives. While some additives may offer temporary benefits, relying on them to prolong oil life is risky. In truth, additives can compromise oil performance and ultimately harm your engine. Stick to high-quality oils and follow manufacturer recommendations for peace of mind.

Myth #4: You Can Skip Oil Changes If You Don't Drive Much

Do you think you can skip oil changes because you don't drive much? Think again. Even if your car spends more time parked than on the road, oil still degrades over time due to factors like moisture buildup and temperature fluctuations. Adhering to both mileage- and time-based oil change intervals is crucial to maintaining engine health. One year is the recommended oil change interval for most vehicles and most oil brands.

Myth #5: All Oils Are Created Equal

Believing that all oils are created equal is a dangerous misconception. Different engines have different requirements, and using the wrong oil can spell disaster for your engine . Whether synthetic or conventional, the key is to use the oil type and viscosity recommended by your vehicle's manufacturer to ensure optimal performance and longevity.

Should I Change All Brake Pads at Once?

Wed, 28 Feb 2024 22:25:00 GMT

You're cruising down the road when you notice that telltale squealing sound every time you hit the brakes. It's time for a brake pad replacement. Here's the dilemma - should you change all the brake pads or just the ones that seem worn out?

Assessing Wear and Tear

Before deciding whether to replace all brake pads or just one pair, it's essential to assess the condition of your current brake pads. Inspect each pad carefully for signs of wear, such as uneven thickness or excessive damage. If one pair appears significantly more worn than the others, it may be tempting to replace only those pads to save money. However, this approach could compromise your braking performance and safety on the road.

Maintaining Symmetry and Balance

Brake systems are designed to operate with a certain level of symmetry and balance. Replacing only one pair of brake pads disrupts this balance, potentially leading to uneven braking and increased wear on other components. Replacing all brake pads simultaneously ensures that your braking system remains properly balanced, maximizing performance and longevity.

Considering Driving Conditions

Your driving habits and typical driving conditions also play a significant role in determining whether to replace all brake pads or just one pair. If you frequently drive in stop-and-go traffic or navigate hilly terrain, your brake pads may wear out more quickly than those of a casual commuter. In such cases, replacing all brake pads ensures consistent braking performance and reduces the risk of unexpected issues on the road.

Cost-Effectiveness vs. Safety

One of the primary reasons drivers hesitate to replace all brake pads is the perceived cost-effectiveness of replacing only what appears worn. While this approach may seem financially prudent in the short term, it could compromise your safety and lead to more significant expenses down the line. Investing in a complete brake pad replacement not only ensures optimal safety but also minimizes the risk of future r epairs and maintenance .

3 Commonly Asked Questions

What Does ABS Mean? Is It Important?

Tue, 30 Jan 2024 16:57:00 GMT

Have you ever wondered what keeps you safe during a sudden braking scenario on a slippery road? The answer lies in a vehicle's Anti-lock Braking System, commonly known as ABS. This system is more than just an automotive buzzword, as you will learn below.

What Does ABS Mean

ABS stands for Anti-lock Braking System. It's an advanced safety feature designed to help drivers maintain control of their vehicle during emergency braking situations. When you brake hard , the ABS prevents the wheels from locking up, which can lead to skidding.

This system uses speed sensors on each wheel and a control unit to modulate the braking pressure. It rapidly pulses the brakes, allowing the wheels to continue rotating and enabling the driver to maintain steering control.

Components Of The ABS

The Anti-lock Braking System (ABS) consists of the following components:

Wheel speed sensors
ABS control module
Hydraulic control unit
Brake lines and hoses
Pump with valves
ABS warning light
Brake pedal and master cylinder

Why is ABS Important

Enhanced Control

ABS plays a pivotal role in enhancing driver control during emergencies. Imagine you're driving fast and suddenly need to stop to avoid a collision. With ABS, when you hit the brakes hard, it prevents the wheels from locking up, thereby maintaining traction with the road. This functionality is crucial because it allows you to steer around obstacles while braking.

Without ABS, the wheels could lock, causing the vehicle to skid uncontrollably, making it impossible to steer. ABS thus offers you the ability to maneuver even in extreme situations, potentially avoiding accidents.

Prevents Skidding

Wheel lock-up during hard braking can lead to skidding, where the driver loses control over the vehicle. ABS prevents this by ensuring the wheels continue to rotate and maintain grip with the road surface. This is particularly important in adverse conditions like wet or icy roads, where the risk of skidding is high. By modulating the brake pressure to each wheel, ABS allows for more controlled and stable braking, significantly reducing the chances of skidding.

Improved Safety

ABS contributes significantly to road safety. In unpredictable driving conditions, such as wet, slippery, or uneven surfaces, the risk of losing control of the vehicle increases. ABS enhances vehicle stability and reduces the likelihood of crashes that can occur due to skidding. This system is especially beneficial in reducing rear-end collisions and accidents on slippery roads, making it a critical feature for safe driving.

Shorter Stopping Distances

In many cases, ABS can help in achieving shorter stopping distances. While it's a common misconception that ABS always reduces stopping distances, its real advantage lies in allowing the driver to maintain control while braking. In certain road conditions, especially where traction is variable, ABS optimizes the braking performance of each wheel, potentially leading to a shorter overall stopping distance compared to locked wheels.

What Happens If The ABS Is Not Working

Loss of Skid Protection

The primary function of ABS is to prevent skidding by avoiding wheel lock-up. If the ABS is not working, this safety net disappears. During hard braking, the wheels can lock, causing the vehicle to skid uncontrollably. This skidding not only makes it difficult to steer the vehicle but also significantly increases the risk of leaving the road or colliding with obstacles or other vehicles. The loss of skid protection is particularly dangerous in wet or slippery conditions, where control over the vehicle is paramount.

Longer Stopping Distances

Without ABS, a driver may face longer stopping distances. ABS allows for the maximum braking force to be applied while maintaining traction, but without it, drivers may have to brake less aggressively to avoid skidding, leading to longer stopping times. This increase in stopping distance can be critical in emergency situations where every inch can make a difference between a safe stop and a collision.

Increased Accident Risk

The lack of ABS functionality heightens the risk of accidents, especially in emergency braking scenarios. The inability to steer away from hazards while braking hard, coupled with increased stopping distances, can make certain driving situations more dangerous. For example, on highways or in heavy urban traffic where sudden stops are more common, the absence of ABS can significantly increase the likelihood of rear-end collisions or losing control of the vehicle.

Immediate inspection and replacement are essential to prevent further harm.

Clicking Sound

A rhythmic clicking sound while braking might be linked to a loose or damaged brake caliper. The caliper, responsible for holding the brake pads in place, can develop issues that result in this distinctive clicking sound. Ignoring it might lead to uneven braking and decreased stopping efficiency.

FAQs for Brakes

1. Why do my brakes squeak sometimes, even if they seem fine?

Brake pads contain a small metal indicator that produces a squeak when they are worn down. Squeaking doesn't always indicate an emergency, but it's a signal that it's time to consider replacing the brake pads.

2. Can I continue driving if my brakes are making a grinding noise?

It's strongly advised against driving with grinding brakes. This sound usually signifies metal-to-metal contact, indicating severely worn brake pads. Continuing to drive in this condition can lead to extensive damage to the brake components and compromise your safety.

3. What causes a clicking noise when I brake?

Clicking sounds are often associated with issues in the brake caliper. It could be due to loose caliper bolts, worn-out hardware, or damaged caliper brackets. It's essential to address this promptly to avoid further damage.

4. Do all brake sounds indicate a problem?

Not necessarily. While some sounds, like squeaking, may be normal wear indicators, others, like grinding or clicking, usually point to underlying issues. Regular brake inspections can help differentiate between routine sounds and those signaling potential problems.

5. How often should I have my brakes inspected?

Regular brake inspections are crucial for the early detection of issues. It's recommended to have your brakes checked during routine maintenance or sooner if you notice any unusual sounds or changes in braking performance.

Giant Air Bag Recall - What's the Deal??

Thu, 14 Nov 2019 14:29:00 GMT

Giant Air Bag Recall

What’s the Deal??

A Japanese company, Takata, is one of the world’s leading manufacturers of automotive safety products, including the air bags supplied to a huge number of cars. Cars and trucks manufactured by BMW, Chrysler, Ford, GM (non-GM made cars only), Honda, Mazda, Mitsubishi, Nissan, Subaru, and Toyota are included. Most models affected were manufactured between 2000 and 2008. For a complete list and to see if there is a current recall on the air bag in your car, see nhtsa.gov and use their “vin search” function to check your car. Right now the list may be incomplete, so please check again in a month or two.

So what’s the deal? Right now (November 21, 2014) the best information suggests that the explosive material that deploys the bag is affected by high humidity, and over time it can absorb enough moisture to change the chemical properties of the propellant. Instead of deploying in a controlled , timed release, inflating the airbag just in time to slow you body as it accelerates forward in a frontal collision, the air bag apparently just explodes instantaneously, not only popping the bag, but hurling pieces of the mechanism towards the driver or passenger. Cars that live in southern states that have year around high humidity are most affected. It is possible that as time goes on, a wider geographic area may be found to be affected as well.

What’s the risk? Graphic news descriptions of “shrapnel” blowing all over the interior of the car in even a minor accident might cause you to consider riding a bike instead of driving (always a good idea anyway). However, the probability of it happening to you, specifically, and your being injured by shrapnel as well, is somewhat lower than your winning the Mega Millions lottery. Basically, if the car you are driving has spent its life out west, it is probably safe. Personally, I would not disable either the passenger side or my own air bag, particularly when I consider that the likelihood of my being in an accident and being saved by the air bag is far greater than being injured by it! If I won the lottery more often, I might reconsider, but as you can probably guess, since I am not writing this from my cottage on the beach in Hawaii, that’s not happenin’.

For more information, see http://www.safercar.gov/Vehicle+Owners/vin-lookup-sites , NHTSA.gov , http://www.nhtsa.gov/About+NHTSA/Press+Releases/Vehicle-owners-with-defective-airbags-urged-to-take-immediate-action

If you bought your car used, be sure and make use of the page in the owner’s manual that informs the manufacturer of your ownership and how to get a hold of you so that if you vehicle is involved in a recall, you will hear about it.

Driving Green in 2019

Thu, 14 Nov 2019 14:28:00 GMT

Driving Green - strategies for buying, driving, and maintaining a motor vehicle with minimal environmental impact.

Most people don’t really consider the lifetime costs of owning a car, let alone its effect on the environment. The purchase price comes out of your pocket, but many of the other costs are shared by everyone, especially the effect they have on our environment. In this article I am trying to provide you a roadmap with different routes selected with a common goal in mind: getting from place to place with the least impact on our environment.

The environmental penalty for driving a conventional car reads like some sort of existential horror story. Burning one gallon of gas consumes all the oxygen in 11,000 gallons of air and produces 20 pounds of CO2. (That’ll tell you how hard your air filter works!) The average passenger car in the US generates 5.26 tons of CO2 driving 11,500 miles in one year. The numbers become stupefying when one considers that there are one billion cars worldwide on the road today!

If you are buying a new car and live in an area where electricity comes from renewable sources like sun, wind and water, you should consider buying an all electric or plug-in hybrid.

If your electricity comes from coal, it’s a wash. The coal burning penalty is so great that it overcomes any CO2 savings from driving a plug in electric, which is why coal has such a bad reputation. In that case, a straight hybrid is the best choice. It makes its own electricity and generates a smaller amount of CO2 than charging a fully electric car with coal or a straight gas engine car.

If those choices don’t work for your dream machine, fuel economy is a reliable predictor of CO2 emissions. The less gas consumed, the less CO2 is pumped into the atmosphere. But of course the reality of getting around looks a lot different. Ideally we live close enough to walk or cycle to our jobs, school, and the store, or we are able to take advantage of public transportation (which is a joke around here if you have ever traveled to Europe). These are the most environmentally friendly ways to get around.

And then there’s money. If you ask your accountant, he will tell you that the least expensive car you can own is the one you are driving right now. Chances are it’s paid for. Its value takes a dive the moment it’s driven off the lot, and doesn’t come back. But if it is running well and passing its biennial smog inspection, there are some compelling reasons to keep driving it, even if the tailpipe emissions are greater that a hybrid or electric car.

The biggest reasons revolve around a car’s overall carbon footprint . The tail pipe emissions are only part of the story. The manufacturing processes used to make a vehicle, while far more efficient than twenty or thirty years ago, still consume plenty of power and generate their own sort of hazardous wastes. And then when our cars finally pass on to that highway in the sky (San Luis Auto Salvage), they generate a whole different and more difficult to control waste stream. (For an interesting discussion of the European Union’s recycling attempts and problems, see https://www.politico.eu/article/europes-ghost-car-fleet-undermines-eu-recycling-targets-illegal-scrappers-commission-circular-economy/ )

So here’s the bottom line: walk or ride a bike if you can. If you can’t, because California generates a substantial amount of power from renewable, a fully electric vehicle is the greenest car you can drive, with huge points if you have solar on the roof of your house. A plug-in hybrid is choice number two and a conventional hybrid number three. For those of us who are not in the market for a new car, a good part of your current cars carbon footprint is water under the bridge, so if it is serving your needs well, best to just take care of it and keep driving it. If you need to replace it, the better the fuel economy, the lower a cars lifetime carbon footprint.

One strong consideration in choosing a car should be the manufacturing and disposal costs to the environment. For example, Subaru’s plant here in the US and it’s two Japanese plants have not sent any waste at all to a landfill in 12 years, with Toyota and General Motors close behind ( https://www.rubiconglobal.com/blog-companies-zero-waste/ ) So even though Subaru doesn’t make a hybrid or electric car right now, it is overall a very green product.

Lots to think about. Writing this article reminded me that I was going to order some grocery bag size panniers for my “town” bike.

Takata Air Bag and Seat Belt Recalls

Wed, 30 Jan 2019 08:34:00 GMT

SAAB Takata Air Bag and Seat Belt Recalls – Morin Brothers Has Them in Stock!

The list of automobiles and trucks fitted with Takata Air Bags that are being recalled continues to grow, with many Saab and a few Saturn autos added to the list. Saab 9-3 models from 2003 – 2011 and Saab 9-5 from 2008 – 2011 are now a part of the giant recall that includes literally millions of cars and light trucks fitted with the Japanese air bags. To see if your car is included in this or any other recall, go to https://www.nhtsa.gov/recalls . Have your vehicle identification number handy, as it makes the query a lot more precise and faser.

Because Saab’s dealership network is pretty much gone, Saab of North America has contracted with Morin Brothers Automotive to take care of recalled Saabs still on the road. Saab provides us with the parts and then reimburses us for the labor to install them. We typically have a dozen or more air bag assemblies in stock, as well as several seat belts for the Saab 9-3 convertible. We can almost always replace the air bag while you wait, but the seat belt assembly take several hours. Call Jesse or Elena at 805-541-2407 to book an appointment.

Engine Oil Takes on New Roles in Engine Management

Mon, 19 Jun 2017 18:28:00 GMT

Engine oil now operates camshaft timing and other vital functions effecting power, fuel economy, and emissions. Car manufacturers have been trying to vary the camshaft timing of the intake and exhaust valve openings for years. While it became common place on racing car engines in the 70’s and 80’s no major manufacturer had been able to reliably incorporate it into production engines until Alfa Romeo introduced it on its fabled two liter twin cam four in 1982. Even then, its performance was unreliable at best.

The breakthrough came with the convergence of several improvements and changes in engine design. Firstly, the thinner lubricants, such as 0/10 weight engine oil, used to lower emissions and improve fuel economy came out, along with the improved machining technology needed to maintain the close tolerances required to use such thin oil. Secondly, increasingly sophisticated engine management computers became capable of improved multitasking, and thirdly, intelligent CAD programs allowed engineers to design and test different cam control configurations before putting them into production in millions of cars and trucks.

The results all come together when you step on the gas in your late model car or truck. The interface between foot and road is so transparent that it is almost impossible to tell if you have a turbocharged 1.4 liter engine or a normally aspirated 2 liter. But there is a catch 22. Because the engine oil no longer merely lubricates rotating engine parts, the quality and cleanliness of the oil is more important than ever. Extended oil change intervals combined with higher temperatures from turbo charging conspire to degrade oil much faster than in the past. Short trips around town exacerbate the situation.

We recently replaced the timing chains, cam timing regulators and the solenoids that control them in a 2015 Mazda. The bill was over $3,000. When we looked at his service history (not a car WE serviced), we found that he had changed the oil exactly twice since he bought the car, once every 15,000 miles, just like the owner’s manual told him to. Our recommendation is to change the oil at least once a year, or more often, no matter what the manual says. And if you typically drive the car on short trips around town combined with occasional freeway blasts to LA or San Francisco, consider changing it more often. Our service advisors, Jesse and Elena, can tell you how often is best for your use, but the bottom line is change your oil!

Ford recalls 230,000 2013 to 2015 vehicles with the 1.6 L GTDI (Gasoline Turbocharged Direct Injection) engines

Tue, 11 Apr 2017 05:00:00 GMT

Affected vehicles equipped with 1.6-liter GTDI engines include:

2014 Escape – Louisville Assembly Plant, Feb. 12, 2013 to Sept. 2, 2014
2014-15 Fiesta ST – Cuautitlan Assembly Plant, Jan. 22, 2013 to May 27, 2014
2013-14 Fusion – Hermosillo Assembly Plant, Feb. 15, 2012 to June 6, 2014
2013-15 Transit Connect – Valencia Assembly Plant, June 13, 2013 to Dec. 14, 2014

Apparently these cars and trucks are prone to coolant leaks, and in spite of the fact they have a temperature gauge to alert drivers that the engine is overheating, if the coolant gets low it will stop circulating and the engine will get hot enough to crack the cylinder head. The crack exposes a pressurized oil galley that sprays hot engine oil onto the hot exhaust with predictably disastrous consequences. Ford’s fix is to install a “Low Coolant Level” sensor in the reservoir and a light on the dash.

This same engine, made by a German manufacturer, is also fitted to a number of Volvo automobiles made from 2010 through 2012.

The bottom line is to learn how to check your coolant (and oil) yourself and keep an eye on the temperature gauge.

Here at Morin Brothers Automotive we check the coolant every time your car is in for an oil change or other service under the hood, but for many of our customers that turns out to be once a year! These engines are running right at the ragged edge, putting out up to 200 horsepower in some models. We strongly recommend using synthetic oil and checking it often.

Bicycling as Transportation

Mon, 06 Feb 2017 09:00:00 GMT

The greenest form of transportation is attached to the bottom of your legs- your feet! The ‘carbon footprint’ of walking is about as small as it gets and it has the additional benefit of being healthy as well. However it takes time, and unless you only have a mile or less to go, getting around by foot can consume a large part of your day. Riding a bicycle, on the other hand, is a lot more efficient. Its’ carbon footprint is equally modest, and in small, relatively level cities like we have here in San Luis Obispo county, you can easily run errands and ride to work in less time than it takes to find a parking space. I began riding a bicycle regularly in my early forties, and have been a member of the San Luis Obispo Bicycle Club (www.slobc.org) as well as several national cycling related organizations ever since. At first I learned a lot about cycling through trial and error, but when I began riding with more experienced riders I gained confidence, greater skill, and achieved a level of fitness that I had not felt since I was 20! If you are new to cycling, or are attracted to the idea of human powered transportation but not sure about how to get started, I would like to share my experience.

First of all, buy a quality bike that fits you from a store that only sells bicycles. You will spend more than you would at Walmart or Costgo, but you will get a bike that is more durable, lighter, and built with higher quality, longer lasting components, as well as one that has been assembled and adjusted by a trained bicycle mechanic. When you buy from a local bike shop the sales person will also make sure that the bike fits you. Nothing will spoil a ride faster than trying to learn on a bike that is too small or too large for you, or is designed for a type of riding you will never engage in.
In addition to a decent bicycle, you will want a helmet, gloves, and, if you find yourself riding a lot, padded bike shorts. Again, your local bike shop can supply you with the proper size of helmet and adjust it correctly. One option for the budget minded is to look at new bikes, find out what size fits you best, and then look for that size in a used bike. I admit to doing exactly that when I first began to ride. However, when I bought my first new bike and had it fitted to me at the bike shop, it was a real revelation. I enjoyed riding more, was more comfortable and rode further with less stress on my body than with the “close enough” used bike I bought at a garage sale for $75.
Once you have a bicycle you like, I recommend that you get some training. When I began riding close to twenty years ago, you got on the bike and hoped for the best. I learned a lot more when I began riding with the San Luis Bicycle Club members, experienced riders all, but nowadays you can actually take classes put on by the City of San Luis and San Luis County Bicycle Coalition (http://slobikelane.org). In the classes trained instructors will help you learn such skills as proper lane positioning, dealing with traffic, and approaching intersections. There is also a more advanced class that teaches you how to deal with a flat tire (it will happen!) and make basic adjustments to the brakes and gears.

There is one thought I would like to leave you with: besides being an efficient means of transportation, bicycling can be a source of fun and adventure. My bicycles have taken me places and allowed me to do things I could only dream about, with people and friends I will treasure all my life. Everyone should have a bike and ride it!

Intensive Electronic Engine Managements Yields Lower Emissions, Greater Reliability, and Superior Fuel Economy

Mon, 06 Feb 2017 09:00:00 GMT

I replaced a Mass Air Flow sensor on a Volvo 850 yesterday. The diagnostic protocol I completed before condemning a $350 part reminded me once again how computers have taken over every aspect of engine management, up to and including “drive-by-wire” systems that actually control the throttle in response to inputs from the gas pedal, engine speed, gear range, etc. In other words, when you press on the gas, there is only an electrical connection to the engine from the pedal. Instead of a cable, there are two range sensors and a single redundant sensor to tell the computer how far down you have pushed the gas. The computer refers to its ‘look up’ tables and decides how much to open the throttle plate. Luckily for us there are redundant sensors and a ‘limp home’ mode that allows the car to be driven in event of a failure caused by an errant 44oz Coke.

The Mass Air Flow sensor I replaced in the Volvo uses a precisely heated wire to tell the computer how much air is flowing into the engine. As outside air flows over the wire, it cools it down slightly, providing an extremely precise varying voltage signal to the computer. Using this information the computer adjusts the amount of time it holds the injectors open, making sure you have good acceleration combined with low emissions and good fuel economy. What normally fails in one of these technological miracles is the “hot wire”. If the voltage signal is off, the computer thinks you are going down the road with the throttle whacked wide open, when in fact you are maneuvering in the parking lot. All of a sudden you are stalling, your fuel economy is down, and the car is hard to start.

Ironically, to meet the needs of the catalytic converter, the fuel mixture needs to be slightly richer than a fuel mixture that would provide the best fuel economy. You can see the tightrope the engineers and designers are walking. If they build a car with great fuel economy, it will be harder to control emissions (as well as being small). If they build a car with great fuel economy and low emissions, it is likely to be expensive, and small like the Toyota Pruis. The great thing about the intensive computer control of every aspect of the engine and transmissions operation is just how well they can make the cars run and still get decent fuel economy and low emissions. Those of you old enough to remember the early emission controlled cars of the ‘70’s will also remember how poorly they ran and what lousy fuel economy they got, especially the big American cars. My son is driving a full sized 2015 Dodge pickup that gets and an average of 18-19 miles per gallon, approximately twice the fuel economy of the ’75 pickup he drove for several years. Not only does it get good fuel economy, but it is extremely reliable as well, and had the same truck been built several years ago, it would have qualified as a ULEV or Ultra Low Emissions Vehicle!

What the future will bring is up in the air, or still on designer and engineers desks. All we can say for sure is that intensive electronic control of automotive systems is here to stay.

Really, Really, Green Cars

Thu, 28 Feb 2013 20:07:00 GMT

In my last article I promised to reveal my choice of “really, really, green cars, and when we will get them”. The good news is that they are here now. The bad news is that they are called ‘bicycles’ and use a form of “biofuel” that includes sweat in the equation. There are several runners up, however, that require more money but less sweat. Some, like the hybrid and diesel cars, are here now, others, like the hydrogen fuel cell and hydrogen fueled cars are still in the making. Each of these options comes with environmental trade offs.

All the major car manufacturers are making gasoline/electric hybrid cars. Some are small and among the most fuel-efficient cars made. Others are larger and even more powerful than their non-hybrid brethren. Their biggest drawback is complexity and the unknown (so far) life expectancy of the batteries. They all still use gasoline and contribute to global warming and pollution, just less so than non-hybrid cars.

Diesel powered cars and trucks also emit their share of pollutants, including hydrocarbons, carbon monoxide, and particulates, but they are more efficient, using less fuel per mile than gasoline powered cars. In addition to the drawbacks of pollution, emissions, global warming, etc. of both diesel and gasoline powered cars is their fuel’s limited supply. Sooner or later we will run out!

Alternative fuels: Not the miracle cure, but definitely an improvement. Biodiesel is so far the “greenest” fuel available today. Energy costs involved in production are low, and efficiency, the available energy per gallon, is relatively high. Ethanol is being touted (especially by Midwest farmers) as the ideal replacement for gasoline, but the energy costs in production are high and its efficiency is low. Biodiesel has the same drawback in so far as production costs are concerned, however it’s efficiency helps it outweigh that disadvantage. The famous Country Western singer Willie Nelson has even come out with his own brand of biodiesel and hopes that it will be marketed along side conventional diesel in truck stops. Right now biodiesel users have to rely on independent producers and suppliers. Locally biodiesel is available at J.B.Dewar on Prado Rd, San Luis Obispo. It is only available in 55 and 5-gallon quantities but they plan to install a conventional pump in the near future.

To sum up, human power is still the greenest way to get around, but bio diesel is a close second and hybrids third, with fuel cell and ethanol power an unknown quantity at this time

Driver Safety

Safety Before Turning the Key

A new study shows that Americans need to be re-educated about proper car safety standards. A public opinion survey, conducted by Public Opinion Strategies for the National Safety Council (NSC) and Castrol GTX Start Up, reveals that 93 percent of Americans are hitting the roads ill prepared - therefore increasing their chances of a road accident. Through this first ever conducted survey on motorists' pre-start inspections and behaviors, it was found that 9 out of 10 respondents admitted to not following the recommended safety guidelines.

The following is the NSC pre-start checklist:

Buckle seat belts and make sure they're properly fastened. In the last 20 years, an estimated 157,500 lives have been saved by safety belts.
Adjust the mirrors. Three out of 10 survey respondents do not adjust their mirrors before short trips (two hours or less), when it is more likely you will get in a crash.
Position the seat and head restraints. Correctly positioned head restraints reduce whiplash injuries resulting from crashes by 28.3 percent.
Secure loose objects Only 34 percent of survey respondents regularly secure loose objects in their cars, even though, on average loose items from luggage to soda pop cans are responsible for 13,000 injuries in accidents nationwide in just one year.
Turn off cell phones In the last five years alone, nearly 300,000 drivers have been involved in crashes attributed to cell phone use.
Look for engine warning lights Three out of four respondents said they always check to see if their light is on; however many admitted to checking the light while already driving.
Check your fuel level In preparing for a trip - large or small - it's necessary to ensure you have enough gasoline in your tank to get there and back. Twenty-five percent of survey respondents said they do not check their gas level.
Allow enough time to avoid speeding and aggressive driving.

Engine Oil – A Necessary Evil

Fri, 15 Feb 2013 13:44:00 GMT

The oil that lives inside the engine of your car or truck is indeed a petroleum product and comes out of one of those sixty-six dollar barrels just like gasoline. It’s origin, use, and disposal has contributed to world wide environmental degradation just like it cousin, gasoline, and, like its’ cousin, it is a necessary part of daily driving. Inside your engine it lubricates in all temperatures, from Alaska to Death Valley, it prevents corrosion and oxidation, and carries away harmful by products of combustion including water, soot, particulates, and raw gas, all the while allowing itself to be ignored by everyone but the most conscientious driver.

Recommended replacement intervals for this hard-working substance are all over the map. Car manufacturers are typically recommending intervals of 7500 to 10,000 miles. Click and Clack of “Car Talk” fame recommend 5000 miles. We at Morin Brothers and most “quick lube” franchises recommend 3000 miles. So who is right? The best answer is “it depends”. The dependent variables are distance, time, and foot pressure on the go pedal. Trips of less than ten miles, stop and go driving, and rapid acceleration force the oil to store far more contaminants than steady state driving (Pizza delivery comes to mind, though having four kids in school may be a close second). Commutes of 20 miles or more and long trips are very easy on the oil. The engine is right up to temperature, the car rarely experiences cooling cycles, and heavy acceleration is unusual. So for one driver, the oil could be overdue at 3000 miles, and for another, a 3000-mile oil change would be too soon. Recommending a 3000-mile interval is a conservative approach. We’d rather be safe than sorry. The manufacturer’s recommendation is not based on ‘best practices”, but on a hypothetical “average driver” that drives 15,000 miles a year at speeds above 35 miles per hour and doesn’t want to spend more that $50 a year in maintenance. Not exactly your real life driver.

A more reasonable guideline might be time, not miles. If you are driving 16,000 miles a year and change your oil every three or four months you will be servicing your car between 4,000 and 5,000 miles - about right. If you are driving 6,000 miles a year and change your oil twice a year, at 3,000 miles between services, you are at a very reasonable interval.

The bottom line is that it is better to change your oil than not. In spite of the environmental impact, keeping your oil clean keeps your engine in good health, which extends the potential life of the car. The longer your can keep your car on the road, the longer you can postpone the much greater impact of disposing of it and manufacturing a replacement.

Priorities in choosing a new car

Fri, 15 Feb 2013 13:43:00 GMT

I’m a car guy, so automotive related stuff always catches me eye. New Times "man in the street" question last week was "If you could purchase a new car today, what would your number one priority be?" Two out of five said "Power, definitely power". One said style, one economy, and one (if I recall correctly) was happy if it just started every time. This gives us a pretty good idea why many of the car ads feature bigger engines and more horsepower and only a few promote their economy. We also get a quick lesson as to why fuel efficiency has been such a hard sell and why many of the new hybrids are actually more powerful than the cars they are meant to replace. Despite the huge jump in fuel prices and the environmental penalty, drivers are still opting for style and power over economy.

Short of a huge shift in the American psyche, what can we do as individuals to "drive green"? First off, if we have a car we depend on, we should keep it in the best running order possible and keep it as long as is economically feasible. The economics of replacing an automobile that is running well and reliably, unless it is so old that even when running well it is a gross polluter, can be calculated just like calculating the payback time for installing an energy efficient heater or dual glazed windows. Even if you buy the cheapest gas sipper you can find, it is still going to cost you $4,000 a year or more for three years. During that time it will lose up to one third of its’ value. The car you are driving now is already paid for. Another reason to keep a car that runs well on the road is the environmental penalty imposed in the manufacture of the replacement car. Even though manufacturing efficiencies are vastly greater than they were just ten years ago, building even a modestly sized car consumes huge amounts of materials and energy, and creates a fair amount of environmental pollution and degradation in the process.

If your treasured vehicle has reached the end of its’ life, by all means replace it. Take a really close look at the kind of driving you do. If you are alone or with one other person in your car most of the time, chose a small hybrid sedan or coupe. If you regularly haul half the soccer team, consider one of the mini vans before looking at that Suburban. Many of the new mini vans can get close to 30mpg on the highway and are capable of hauling up to nine people and gear! If you really need to haul stuff, take a look at diesel power in trucks. Despite the initial added expense of opting for a diesel engine, as well as the more expensive fuel (here in CA), diesel powered trucks can get more that twice miles per gallon and potentially last twice as long as gas powered trucks.

To sum up, the car you drive right now may be the cheapest car you can own, but if you have to replace it, think green.

Next month: Really, really, green cars, and when we are going to get them.

Competency and Trust

Auto Repair - Competency and Trust

Establishing a good relationship with a repair shop you can trust provides peace of mind throughout the life of your car. It's a proven fact that motorists who build such a relationship, along with learning more about proper maintenance, typically enjoy a more satisfactory vehicle repair experience.

Finding a competent auto technician need not be a matter of chance. Much of the guesswork has been eliminated, thanks to national program conducted by the non-profit National Institute for Automotive Service Excellence (ASE).

ASE tests and certifies automotive professionals in all major technical areas of repair and service. With nearly 400,000 currently certified professionals, the ASE program is national in scope and has industry-wide acceptance and recognition. ASE-certified professionals can be found at every type of repair facility, from dealerships, service stations, and franchises to parts stores, independent garages, and even municipal fleets.
