BMW 320i Oil Filters

The engine powering your BMW 320i needs clean motor oil running through it to operate at its best. Unfortunately, even the freshest motor oil still contains impurities left over following the refinement process. That's why your car has an oil filter in place.

How Oil Filters Work

An oil filter serves the same role as an air filter or fuel filter. It prevents contaminants from getting into your essential engine parts, stopping them from accumulating and cause issues. It does that first by removing any pollutants from the motor oil that's heading to your engine. Since the oil also gathers impurities as it passes through your engine, the filter removes those as well before the oil heads back to the engine to repeat the process.

Unfortunately, oil filters don't last forever. If they don’t get clogged up, they eventually degrade with age. In either case, you'll want to replace yours to ensure optimal engine performance.
