Oil filters have a very important function and if your oil filter has poor quality, it can shorten the life of your engine and cause other parts to fail as well. This small part of your car’s lubrication system plays an important role in protecting your engine from premature wear. All the moving parts in the engine need clean oil to properly lubricate them. Tiny bits of metal chip off of various engine parts while it’s running. If these bits of metal are allowed to recirculate through the oil, they could break off other bits of metal, which eventually will cause erosion in the engine. A quality oil filter helps prevent this erosion from taking place. The oil filter cleans the oil as it passes through the filter and prevents abrasive contaminants from damaging the parts in the engine.
