MB 236.5

Approval MB 236.5 is a technical requirement from Mercedes‑Benz for automatic transmission fluids, developed to ensure stable viscosity, high oxidation resistance and wear protection under high loads and frequent gear shifts. Fluid that meets MB 236.5 is intended for passenger and commercial Mercedes‑Benz vehicles equipped with 6‑, 7‑ and 9‑speed automatic gearboxes (e.g., 7G‑Tronic, 7G‑DCT, 9G‑Tronic) and torque‑controlled electronic transmissions. The specification requires a synthetic base with a low molecular solution level, guaranteeing rapid cooling, minimal deposit formation and optimal operation of hydraulic valves. Since MB 236.5 does not involve interaction with after‑treatment systems (DPF, SAPS), it is suitable for any engines connected to the listed transmissions, without restrictions regarding catalyst technologies. When selecting oil on xenum.ua, products with this marking, such as XA‑TRAN DX IIIH, XA‑TRAN DX VI or XA‑TRAN UNI, provide full compatibility and durability for your gearbox.
