How Does an Oil Filter Work?

Shaped similarly to a metal can, the oil filter is a component that helps filter debris from oil. It works by being inserted onto an engine matting surface and including a seal to prevent oil leaks. Small holes around the perimeter of the filter allow oil to enter, which then passes through its filtering internal system often made out of synthetic fiber. After filtering, the oil will be forced out of the filter through one large center hole directly back into the engine. After passing through the engine, the cycle will repeat.

It’s important to make sure that your vehicle maintains a clean oil filter. As the filter collects debris, its ability to continue collecting debris will falter, causing your oil to get dirty quicker than usual. Since dirty oil can cause wear and tear to the engine, it’s crucial to change your oil filter once in a while to prolong the engine life and save yourself money later on.

When Should I Replace My Oil Filter?

Now that you know how important it is to change your oil filter, when should you replace it? It’s recommended that you replace your oil filter with every oil change as the filter will last about 3,000-5,000 miles. However, you could replace it during every other change. Thankfully, the oil filter replacement is relatively cheap and shouldn’t put a big dent in your wallet.
