Sure, you know that your car has an oil filter, but do you know what it actually does? And do you ever wonder why your mechanic keeps replacing it? If you were to think back to all of the vehicle maintenance lessons you were taught growing up, none of them really addressed your oil filter much more than to tell you that it ‘needs to be replaced once it gets full’. And while this makes sense in general terms, it doesn’t really teach you anything about how your oil filter works or why you are actually replacing it.

Learn About Your Oil Filter and Why It Needs to Be Replaced

To help you learn more about why you are paying your mechanic to replace your oil filter every time that you take your car in for a service, Synthetics Northwest has a great post below.

Let's Start With Why Your Engine Needs Oil

The best place to start is with a basic explanation of why your engine needs oil. But don’t worry, you won’t need to take notes. If you were to imagine what the insides of your engine looked like, there would be any number of engine parts tightly packed into their space where they provide a range of functions from simply moving up and down to facilitate the ignition process. What they are all there to do, however, is keep your engine going. To do this, the majority of these parts are required to interact with each other. In the terms of your engine, this means sliding, grinding, and scraping against each other at high speed and at extreme temperatures. To prevent your engine from building up so much friction that it eventually ceases to operate, also known as seizing, your car’s engine oil coats each part with a protective barrier. Additionally, it also flows through your engine facilitating smooth interactions between each of the parts.

That Makes Sense. But If It Goes In Clean, Why Does It Need to Be Filtered?

While the oil that goes into your engine is clean, your engine certainly isn’t. In addition to any contaminants which are currently sitting in your engine, as the oil starts to come to its end life it can break down and cause contaminants to flow through your oil lines and accumulate where they can cause serious damage. It’s the role of your oil filter to make sure that these minuscule contaminants are picked up and not left to keep circulating through your engine. In fact, if you have ever heard the term 'general engine wear' then there is a good chance that a dirty oil filter had a solid part in allowing the wear to occur.

Got It! So How Does It Work?

To keep it as simple as possible, think of your oil filter as a soda can. At the top of the can is a hole where you oil makes it way in. At the bottom is another hole where your oil comes out. In the middle of the can is a thick fibrous sponge. While you are driving, oil is pushed through the top hole at such a high level of pressure that it is forced through the sponge and out of the bottom. As the oil is pushed through the sponge, the contaminants are captured and prevented from exiting the oil filter and, in turn, prevented from returning to your engine.

I Think I Might Know What You Are About to Say

If you have been following then you likely know what comes next. Just like any type of filter, the one inside your oil filter casing can and will become too clogged to function. When this happens, a switch is triggered and your dirty oil bypasses the filter and it allowed to continue to circulate through your engine.
