Oil Filters: How do they work?

Merriam-Webster defines a filter as a device that is used to remove something unwanted from a liquid or gas that passes through it. For the sake of this review, the fluid is oil -- conventional motor oil or synthetic motor oil. The device is the oil filter. And the unwanted “something” can be debris or even just tiny hard particles.

From what we know already about filters and their jobs, we can just build on that concept to understand how the oil filters work. An oil filter is basically a tiny can with a special screen inside, typically made of synthetic fiber, and a base plate with some sealing gaskets on one end. The base plate usually has small perforations around one central hole that is threaded to connect with the oil filter assembly. As your car is running, the oil pump forces the oil through the smaller holes in the sealing gasket and into the oil filter. The oil passes through the filter which catches the debris and is then pushed back into the engine.

Oil filters are pretty simple devices, yet they are so vital to a healthy engine. The best oil filter brands are reputable and will use these higher quality materials. Keep this in mind when selecting an oil filter.

Best oil filter

Some mechanics recommend changing your oil filter whenever you change your oil. It is so simple, you can do it on your own.

How to choose the right oil filter

All oil filters are slightly different. It is imperative to make sure you get the correct one when you are changing your oil. Small differences in the individual oil filters can cause a significant headache or even damaged parts. The main thing to look for is the thread size and gasket size. You must make sure your oil filter matches the dimensions on your vehicle. You should consult your car’s owner's manual or reference a parts catalog to find the best oil filter for your car. Be cautious, if you get the wrong oil filter, you could have anything from a slight oil leak to a significant leak -- or maybe the oil filter will just fall off. Obviously, these scenarios are horrible news for you and your engine.

What else do you need?

You’ve probably already referenced your vehicle’s owner's manual, or cross-checked a part catalog and chosen the right oil filter. You might need some other tools to get the job done. One device you want to consider is an oil filter wrench. There are a few different types and models of oil filter wrench, but choosing one shouldn’t be too difficult. Most are adjustable and will really help to grip the oil filter canister, especially if it's oily. Some look like a giant socket wrench and are designed to slip over the hexagonal shape on the bottom of the oil filter. Finally, you might find an oil filter wrench that it shaped like a giant claw. You will notice the benefit of using an oil filter wrench versus using oily hands to try and tighten the oil filter.

What good is an oil filter, and oil filter wrench if you don't have engine oil. You will definitely want to consult your owner's manual to find out what type of oil you should be putting in your car. You will also want to choose whether to use conventional motor oil or upgrade to synthetic motor oil. It is possible to upgrade from conventional to synthetic, but not so much downgrading from synthetic to conventional. Whatever route you go, double check that your new oil filter will support it.
