MAN M3271-1

MAN M3271‑1 is MAN’s technical approval for engine oils intended exclusively for their medium‑ and heavy‑duty diesel engines installed in trucks, buses and light commercial vehicles. Oil that meets this standard must provide a minimum viscosity in the range 10W‑40/15W‑40, high oxidation resistance, wear and corrosion protection, as well as effective dissolution and neutralization of deposits in the combustion chamber. The specification requires a low SAPS content, guaranteeing compatibility with after‑treatment systems (DPF) and catalysts, preventing their fouling. MAN M3271‑1 covers both turbocharged and supercharged engines with selective catalytic reduction (SCR) technology, ensuring stable operation under various load and temperature conditions. When selecting oil on xenum.ua, you should look for products marked with this approval, for example XENUM DIESEL SYNTH 10W40 E4/E6/E7/E9, which meet all the requirements of MAN M3271‑1.
