How Do Oil Filters Work?

The Science and Purpose Behind Oil Filters Inside Vehicles

If you drive a vehicle that uses oil, you know that oil will get dirty eventually and require a change. However, did you know that your vehicle also has an oil filter to help keep that motor oil cleaner for longer? At U.S. Auto Sales, we will explore how oil filters work and the importance of these small gadgets.

What is an Oil Filter and What Does It Do?

An oil filter appear like a metal can that is placed on an engine matting surface. It includes a seal to help keep oil from leaking out of the system. Oil filters also have numerous small holes around the perimeter of the can with a large hole in its center. To send oil into the oil filter, the engine pumps the oil directly into the filter through the smaller holes. The filter material, often made from synthetic fiber, is on the inside of the can to collect debris. After the oil passes through the filter, it will re-enter the engine through the large central hole.

How Often Should I Change the Oil Filter?

Oil filters are vital components to vehicles that operate on oil. Without a good oil filter, dirty oil will continue to collect debris and can cause engine wear and damage as time goes on. So, how often should you change the oil filter, you may wonder? Since oil filters tend to last for around 3,000-5,000 miles, it’s recommended that the oil filter gets changed every time the vehicle gets an oil change to help ensure that the new oil stays clean until your next scheduled change.
