What Is An Oil Filter And Why Is It Important?
An oil filter is a part that looks like a soup can. Inside the oil filter is a pleated paper filter. An oil filter is necessary because your Subaru needs something to filter the oil as it cycles through the engine. As oil runs through the engine, it picks up a lot of dirt and debris the engine produces. The oil filter traps most of the dirt and debris in the oil. This helps to prevent the contaminants from causing engine wear.
