Mann Filter oil filters reliably purify oils of dirt and solid particles such as dust, abraded metal, carbon deposits, soot particles, etc. Engine oil lubricates all the moving and functional engine parts. As a result of combustion, particles of dirt and combustible residue, such as soot, escape into the engine oil. They contaminate the oil and make it more viscous. This means that the oil supply is not adequate and protection from corrosion can no longer be ensured. As a result, engine performance is impaired and fuel consumption increases. In the worst case, the engine can be damaged. Mann Filters are used with engine oil, hydraulic oil and gear oil.
