Myths About Engine Oil

Mechanic Adding Oil to an Engine

Getting your oil changed regularly is just part of being a car owner. It’s not the most fun thing in the world, but it is necessary. Your engine needs oil to run properly and efficiently. With that being said, there are a lot of misconceptions about your engine oil. Today in the Thompson Sales blog, we’re going to be clearing up some of those misconceptions.

You Have to Change Your Oil Every 3,000 Miles

This myth may have been true in the old days, but engine oils and engines themselves have advanced a lot since then. Modern engine oil works much better than it did back when 3,000 miles was the rule, and engines have been engineered to be much better at efficiently using oil. It depends on your vehicle and the oil you use, but many vehicles can go 5,000-7,000 miles before they need an oil change. You should also check your manufacturer recommendations to be sure!

Dark Motor Oil Means Dirty Motor Oil

Many people assume when they check their dipstick and find that the oil is dark, instead of the light amber color, that the oil is dirty. Dirty oil can muck up your engine and cause issues, but just because the oil is dark doesn’t mean it isn’t good anymore. Modern oil will turn dark in between oil changes because it’s catching the contaminants and preventing them from building up in the engine. If you changed your oil a few thousand miles ago and found the oil to be dark, it’s not necessarily something you have to worry about. You’re more than likely fine until your next scheduled oil change.

I Don’t Have to Change My Oil Filter Every Time

Sometimes people change their oil, but they don’t change the oil filter. This is definitely not recommended. The old filter is likely dirty, and you don’t want to pour your new clean oil through a dirty filter. Make sure you’re switching out your oil filter every time you get an oil change.
