MAN 3775

MAN 3775 is a technical approval developed by the German commercial vehicle manufacturer MAN for engine oils used in their medium‑ and heavy‑duty diesel engines. The specification requires high oxidation resistance, effective cylinder wear protection and deposit reduction, as well as stable performance over a wide range of temperatures and loads, including turbocharged units. Oils that meet MAN 3775 are suitable for engines of series D08, D20, D38, D286 and similar, installed in trucks, buses and specialized fleets. When equipped with after‑treatment systems (DPF) they ensure compatibility and do not cause excessive sulfate deposit buildup, maintaining filter efficiency. By choosing XENUM products bearing the MAN 3775 label, such as DIESEL POWER 10W40 or 15W40, you receive an oil that meets MAN requirements and guarantees engine durability and reliability.
