Most drivers know how important engine oil is, but what distinguishes modern engine oil from those of the past may not be common knowledge. It can be easy to assume that issues affecting older engines still apply today. Before performing a DIY oil change or visiting a mechanic for scheduled maintenance, learn about these four modern engine oil myths and the truth behind them.
Myth #1: Mixing in Additives Will Improve Your Vehicle’s Performance
It’s true that oil additives can improve your vehicle’s performance, but you probably don’t need to add them yourself. The misconception is that you need to add additional material to your vehicle’s recommended oil to get the promised performance results.
Check your owner’s manual. Unless you have a high-performance engine or other unique need, the oils recommended there will be all that’s necessary to achieve optimal performance. This is because many modern oils already have the additives needed to boost your car’s performance by optimizing the oil’s viscosity index or keeping the engine sludge-free. Yes, additives will improve your vehicle’s performance. No, you shouldn’t need to mix them in yourself.
Myth #2: Synthetic Oils Cause Leaks
Some drivers may want to work exclusively with petroleum-based oils because they think that synthetic oils will cause leaks. Although it’s true that synthetic oils affected engine seals in vehicles circa 1970, this is no longer a concern with newer cars and modern oils. Again, check your owner’s manual to confirm which oils will work with your engine. Synthetics are perfectly safe if appropriate for your vehicle.
Myth #3: You Must Change Your Oil Every 3,000 Miles
This is a popular misconception that’s absolutely incorrect given the technological strides that have been made with modern oils and engines. Vehicles do not need an oil change every 3,000 miles. Instead, you should consult your owner’s manual for more information about ideal change intervals. Note that today’s engines and oils can go without a change for approximately 8,000 miles, though this will vary depending on use and other factors.
Myth #4: If the Oil Is Dirty, It Needs to Be Changed
Early one morning, you perform a quick engine check in your garage. You pull out the dipstick, and, as you clean the gauge, you notice that the oil is very dark. Do you need an oil change? Nope! Though dark or even black oil indicates use, it doesn’t tell a driver much more than that. Yet again, you should follow the oil change interval requirements listed in your owner’s manual. Your oil should have no problem hitting that mark regardless of its transparency.
Change Your Oil the Right Way
Using the incorrect oil will obviously not be good for your car, so it’s important to check your owner’s manual and conduct research as needed. You can also take your car to a local dealership in South Carolina for more information. There you can speak with a mechanic, get answers to any questions you have, and schedule an oil change if one is due.
