MAN 3377

MAN 3377 is a technical approval developed by the German manufacturer of commercial vehicles MAN, which defines the requirements for engine oils intended for their medium‑ and heavy‑duty diesel engines. The specification calls for high oxidation resistance, wear and corrosion protection, as well as maintaining stable viscosity over a wide temperature range, ensuring long‑lasting operation of turbocharged engines in trucks, buses and tractors. Oils that meet MAN 3377 are formulated with low sulfate, aromatic and phosphorus compound content (low‑SAPS), making them compatible with after‑treatment systems (DPF) and catalysts without compromising their efficiency. This approved specification is targeted at MAN D08, D20 and other series engines that operate under high‑load conditions and require optimal protection during long‑haul trips. When selecting a lubricant on xenum.ua, for example XENUM DIESEL SYNTH 5W30 E4/E7, you receive a product that fully complies with MAN 3377 and guarantees reliability and cost‑effectiveness of your vehicle’s operation.
