The function and role of the oil filter.
2025-01-21

The main function of the oil filter is to remove impurities such as dust, metal particles, carbon deposits, soot, and water from the engine oil, keeping the oil clean and protecting the engine from the effects of these impurities, thereby extending its lifespan. During operation, the engine generates metal shavings, dust, and other impurities that continuously mix into the oil. The oil filter filters out these impurities, ensuring that all parts of the engine receive clean oil lubrication, serving the functions of lubrication, cooling, and cleaning, which helps to extend the lifespan of internal engine components such as the crankshaft, connecting rods, camshaft, turbocharger, and piston rings.
