Engine oil is permanently contaminated — combustion residues, dust, oil carbon, soot, abrasion particles, and condensates accelerate the wear of the engine components.
Clean engine oil reduces friction, cools the engine parts, protects against corrosion, and seals the combustion chamber.
MAHLE oil filters reliably keep out the dirt particles. The stable pleat geometry assures cold-start stability, peak loads of up to 20 bar are compensated by the high pressure resistance of the housing.
