An oil filter is an important part of keeping your vehicle running efficiently, however it’s not always something you’d pay much attention to unless you’re having it replaced. Choosing the best car oil filter depends on a number of factors, so we will look at some important aspects such as; what an oil filter actually is, how oil filters work, what to consider when choosing an oil filter for you vehicle, how often you should change your oil filter and then look at some of the best oil filters there are to choose from and the benefits and features of each of those oil filters.

Overall, oil filters are an important component of your vehicle and it would benefit from knowing you have chosen the best one for you vehicle and maybe a little information as to how they actually work.

What Is An Oil Filter?

Simply put, an oil filter does as the name would suggest – it filters your vehicle’s oil, getting rid of any impurities and contaminating substances that might be found in your oil. Think of it as a water filter if that helps. The device is typically the size of a tin can and without a fully functioning oil filter, damaging substances or even solid substances get into the fuel and can wear down integral parts of the engine faster or even stop pistons and valves from working, which can result in a very expensive fix. So, as you can see, an oil filter is a very important piece of the system and needs to be part of every tune up.

How Do Oil Filters Work?

The outside of the filter is essentially a metal can which has a sealing gasket on it which allows the filter to be tightly fixed onto the engine’s surface. The base plate of the can holds the gasket in place and is pierced with holes just inside the gasket. There is also a hole that runs straight through the center to connect with the oil filter assembly on the engine block. Inside the can is the actual filter material, which is commonly made from a synthetic fiber.

The oil pump moves the oil directly to the filter where it enters the holes in the base plate. The dirty oil is pushed, under pressure, through the filter material and back through the central hole. Typically the filter is able to stop particles as small as 25-30 microns, human hair being around 70 microns.

Choosing The Right Oil Filter For You Vehicle

Choosing the correct oil filter for your vehicle is extremely important, while they may look very similar, choosing one that is not compatible with your vehicle could result in catastrophe. The minute differences in the gasket and/or thread size can be the difference as to whether your filter works or not. The best way to determine what sort of filter will or will not work on your vehicle is to consult your owner’s manual. It is best to be certain, as a filter that doesn’t work with your vehicle can lead to serious engine damage.

How Often Should You Change Your Oil Filter?

More often than not, this particular question being asked can result in a myriad of answers and it really depends on exactly who you are asking. While car manufacturers advise that you only change your oil filter every other time you change your oil, the oil manufacturers themselves strongly advise that people should be changing their filters every single time they change their oil which typically occurs around every few months depending on your vehicle. While other say that it should be changed as soon as the service engine light comes one and some say that if you drive in stop-and-go traffic regularly then you should be changing your oil filter even more often. So, as you can see, it definitely varies. Your mechanic will generally advise on the right time to chance your filter when they are servicing your vehicle.
