MAN 341 Type Z-2

MAN 341 Type Z‑2 approval defines the requirements for engine oils intended for modern MAN medium- and heavy-duty diesel engines, in particular the TGL, TGM, TGX, L2000 series and their turbocharged variants with after‑treatment systems (DPF, SCR). Technically, this oil must provide high cylinder protection, stable oxidative stability, effective soot dissolution and low SAPS content, which guarantees compatibility with catalysts and soot filters without premature fouling. The specification calls for a minimum viscosity of 15 W‑40 (or equivalent) and compliance with wear, corrosion and thermal expansion requirements, allowing optimal power and fuel‑system efficiency. Oils that meet MAN 341 Type Z‑2 are also suitable for engines that previously required MAN 339 Type Z2 approval, ensuring uninterrupted operation under various load conditions. When selecting on xenum.ua you can use the “MAN” filter to find products that exactly match this approval, for example the transmission oil XENUM X‑TRAN 75W90 GL4/5.
