As the motor oil runs through the engine, it slowly breaks down. As it breaks down, it leaves contaminants in the oil. It also picks up tiny metal particles as the engine wears. The more contaminants the oil accumulates, the muckier it gets. That can seriously damage the engine. That’s why Toyota designed your car to have an oil filter between the engine and the oil pan.

An oil filter is a cylinder-shaped part with a pleated filter inside. Its sole purpose is to filter the contaminants out of the oil to keep the oil clean until the next oil change.

How An Oil Filter Works

The spin-on oil filter is the most common type of oil filter. A spin-on oil filter contains several important components:

  • A metal housing
  • A cylinder-shaped centrifugal pleated filter
  • A bypass valve

The oil filter filters the oil that comes from the oil pan to the engine. As the oil enters the filter on one side, the centrifugal pleated filter spins as it filters the impurities out of the oil. The clean oil then exits the filter on the other side.

If the oil filter is too clogged up, the dirty oil will pass through the bypass valve without being filtered.
