Do you think you know oil changes? Think again. Despite being a routine automotive task, there are numerous myths circulating that could potentially harm your engine. Let's explore some prevalent misconceptions surrounding oil changes to ensure your engine remains in top condition.

Myth #1: Change Your Oil Every 3,000 Miles

It's time to debunk the myth that you need an oil change every 3,000 miles like clockwork. While this was once the norm, modern vehicles and advancements in oil technology have extended oil change intervals. Most cars today can safely go between 5,000 to 10,000 miles before needing fresh oil, as many manufacturers recommend.

Myth #2: Thicker Oil Equals Better Protection

Contrary to popular belief, thicker oil isn't always better for your engine. 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.
