MAN 339 Type Z1

MAN 339 Type Z1 is a technical approval that defines the requirements for engine oils for medium‑ and heavy‑duty MAN diesel engines, in particular the D08, D20, D26, D38 and D45 series installed in trucks, buses and special equipment. Oil that meets this standard must provide high oxidation resistance, wear protection at high temperatures, viscosity control of 10 W‑40 or 20 W‑50 and effective lubrication of turbocharged systems. The specification includes compatibility with after‑treatment systems (DPF) and catalysts, allowing low emission levels in accordance with European environmental regulations. It is an extension of the MAN 339 Type V1 requirements, so oils approved under Z1 also satisfy the earlier requirements of this group, simplifying the choice for service centers updating their technical base. When purchasing on xenum.ua you can use the “MAN” filter and find products such as XENUM DIESEL POWER 20W50 E7 or XENUM DIESEL SYNTH 10W40 E4/E6/E7/E9, which precisely meet MAN 339 Type Z1.
