Contaminants pose a threat to the health of your engine. Oil filters, are charged with sifting out any physical contaminants This is why you need to replace your oil filter, making sure your motor lasts as long as possible. If you on a regular basis or often find yourself on dirt roads, you may want to change your lubricants more often than required in your vehicle’s manual, which may, in fact, come with a heavy-duty replacement schedule.
A filter is only effective if it’s able to strain and store more grime. Once full, it no longer provides any protection from unwanted contamination. If left on too long, it’s also possible for certain designs to have their filter media disintegrate internally and then send all that’s been filtered out back into the motor. This can include dirt, dust or sludge that’s been loosened by the detergents in the lubricant. By removing and storing these particles, the filter prevents them from circulating through, reducing friction and prevents wear that can potentially damage your engine.
