An engine oil filter works by removing contaminants and impurities from the engine oil as it circulates through the engine, ensuring cleaner oil reaches critical engine components.

Signs of a clogged or malfunctioning engine oil filter can include reduced oil pressure, engine overheating, increased engine noise, poor performance, and the presence of metallic particles in the oil.
