All About Engine Oil Filters

Most of us know how important clean oil is for a healthy car engine. The oil keeps all engine components properly lubricated and prevents them from overheating. But what is an oil filter and what role does it play?

The automotive service experts at Campus Automotive in Blacksburg, Virginia are here to explain how an oil filter works and why it’s so critical for your car.

What’s an Oil Filter?

As its name suggests, an oil filter filters out debris and other contaminants from your car’s engine oil. Without an oil filter, your engine oil would quickly become saturated with gunk and not be able to optimally function.

How Does an Oil Filter Work?

The outside of an oil filter is a metal can that has a sealing gasket. This holds it securely in place against the mating surface of the engine. The base of the can holds the gasket and has small holes near the inside of the gasket. A central hole leads to the oil filter assembly. Inside of the can is the filter material, typically made from synthetic fiber.

The oil enters the filter through the small holes on the base plate. “Dirty” oil passes through the filter material where it’s “cleaned.” The clean oil then passes through the central hole and returns back into the oil passages of the engine.

When Should I Change My Oil Filter?

You should change your oil filter with every oil change. As a general rule of thumb, you should get an oil change every 7,500 miles or so. Consult your driver’s manual for recommendations for your vehicle’s unique needs.

If your oil filter needs to be changed, you may experience:

• Premature engine wear
• Low oil pressure
• Less engine lubrication

To keep your engine in excellent condition, never skip getting an oil filter change. The oil change experts at Campus Automotive in Blacksburg, Virginia can perform a swift oil change and get you back on the road in no time at all.
