If you own a car, have ever owned a car, talked about cars, or been around people who own cars, chances are you’ve heard about checking and changing your motor oil. It’s at the top of the maintenance to-do list and it’s a bad idea to procrastinate doing it. But we’re rarely told why changing oil is so important. So we’ll tell you!
Oil has a lot of uses. The first is reducing friction. The more friction an engine generates with its moving parts, the more heat it produces and the quicker it wears down, both of which are bad and can lead to engine failure. On the other hand, a smooth-working engine will be more efficient both in terms of power and fuel economy.
Oil can also further reduce heat simply because it draws it away from the combustion chamber as it moves out of it. It also helps prevent carbon and varnishes from accumulating in the engine. In other words, oil keeps your engine smooth, cool, and clean. But motor oil doesn’t stay in pristine condition throughout its whole life. Eventually, the additive breaks down, particles build up too much, and it can start being more trouble than it’s worth.
So now that you understand why changing oil is so important, how often should you do it? Well, that’s something everyone disagrees about, because it depends on make and model, the kind of oil you use, and the kind of driving you do. Your best bet is to check your owner’s manual and, if you’re still not sure, aim for every 3,000 miles or 3 months, whichever comes first.
