MAHLE Oil Filters

MAHLE has long been manufacturing high-quality oil filters for many large automobile and engine manufacturers—and of course the same machines produce identical filters for the aftermarket. This high level of quality has clear advantages: it ensures reliable function, good engine protection, and satisfied customers. The diversity of types is constantly increasing, however, as new engine architectures allow less and less space in the engine bay. Areas of application range from petrol and diesel engines for passenger cars and commercial vehicles to motorcycles and small engines. Because optimal lubrication of the bearings is extremely critical in all of these engines, all vehicle manufacturers require that oil filters be changed regularly.

MAHLE oil filters reliably prevent contaminants from entering the lubrication system and maintain oil quality as well as the performance and efficiency of the engine. Thanks to stable pleat geometry, cold start stability is assured. Load peaks up to 20 bar are compensated due to the high pressure resistance of the housing. A pressure relief valve guarantees the oil supply under all conditions – for viscous oil encountered during cold starts or at low temperatures, for extremely contaminated filter elements, or when the replacement intervals have been exceeded. A non-return flow valve prevents the draining of the filter when the engine is switched off and ensures adequate oil supply when the engine is started. High-grade sealing materials and custom-fit connecting pieces assure reliable separation of contaminated and filtered oil.

However, an important consideration for optimum functioning of oil filters is that filters are replaced within the maintenance intervals stipulated by the automobile manufacturers
