What Is the Purpose of an Oil Filter?

A vehicle's oil filter has two important functions: filter out contaminants and keep oil in the right place, at the right time. Your engine can’t perform efficiently without clean engine oil, and your motor oil can’t do its job without an oil filter. Operating your car with a clogged oil filter can do more than affect your oil quality, it can damage your engine and its surrounding components. Understanding what your oil filter is and how it functions can better your awareness of when it’s time for an oil change and filter replacement. 

The oil filter collects all the harmful debris, dirt, and metal fragments that it may have picked up along its flow. If these contaminants get into your lubricant, it can severely damage the engine.


How Often Does It Need to Be Replaced?

Every 3,000 miles you drive, your oil has gone through the oil filter 12,000 times! It not only means you need an oil change, but it means you need a filter change too. Many manufacturers recommend getting these two services at the same, so it's easier to remember. However, you should always make sure by checking with your vehicle's owner’s manual. If you fail to get your filter changed, your car may display the following signs:

  • Difficulties accelerating
  • Metallic clanking noises under the hood
  • Low oil pressure and its warning light comes on your dash
  • Changes in exhaust color
