Before cars came equipped with oil filters, oil changes were frequent as engine combustion contaminants quickly mucked up the motor oil. A crucial part of routine maintenance, it is now recommended to change your filter every time you change your oil. It used to be time for a change every 5,000 miles, but now there are many types of oil filters, including extended life oil filters which can last 10,000 miles or more. New filters ensure filtering efficiency to keep your oil clean and your engine properly lubricated.

Bad oil filter symptoms can include dirty exhaust, low oil pressure from oil leaking, or metallic sounds and sputtering from the engine. These symptoms only get worse as the oil filter gets older. Don’t set yourself up for engine damage down the road, get the parts you need today.

On the outside, the oil filter looks like a metal can with a sealing gasket on top to hold the filter flush to the engine’s mating surface. Oil is taken from the engine to pass through the filter media. The media is the part inside the filter which looks like paper. In fact, media were traditionally made of paper and often still are, although some filters now use synthetic filter media which are better for trapping small contaminants over more miles.

Full flow filters contain primary media which stops particles as small as 25 microns, and lower oil flow filters also include a secondary media capable of stopping particles between 5-10 microns. Oil enters through the series of small holes just inside the sealing gasket. After soaking through the media, the oil leaves through the big hole at the center of the filter’s top.
