How Oil Filters Work and Why They’re Important

It’s Important to Understand How Your Oil Filter Works

Most drivers understand the importance of consistent oil changes. Motor oil keeps your car’s engine lubricated and prevents it from overheating. But did you know that in addition to the oil itself, your oil filter also plays an important role in your car’s health?

The auto repair professionals at MJ Brothers Auto & Truck Repair in Raleigh, North Carolina, are here to explain everything you need to know about oil filters.

What is an Oil Filter and How Does It Work?

An oil filter is literally what the name implies: it filters out contaminants from your engine’s oil.

The outside of the oil filter is made of a metal can with a sealing gasket that holds it securely against the engine’s mating surface or two parts of the engine that contact each other. The can’s base plate is perforated with small holes, and a central hole is threaded to connect with the oil filter assembly on the engine block. Inside the metal can is the filter material. Motor oil is moved via the engine’s oil pump directly into the filter, where it enters from the holes on the perimeter of the base plate.

The dirty oil passes through the filter material and then back through the central hole, re-entering the engine.

Why Are Oil Filters Important?

Over time, gunk and debris can build up in your engine oil. If left unfiltered, the dirty oil can wear down the surfaces of your engine, leading to engine damage and even failure.

Ideally, it would be best if you were getting your oil filter replaced during every other oil change. For instance, if your oil gets changed every 7,000 miles, you should replace the filter every 14,000 miles.
