MB 236.21

MB 236.21 is the official technical specification of Mercedes‑Benz for transmission oils, developed for automatic gearboxes, including 7‑speed DCT (PowerShift) and 9‑speed ATF, installed in passenger and light‑commercial models with gasoline and diesel engines of the C, E, S, V series. The specification requires viscosity stability at high temperatures, high oxidation resistance, wear protection and maintenance of a low friction coefficient, ensuring smooth operation of valve mechanisms and durability of friction elements. Oils that meet MB 236.21 have an appropriate SAPS range, allowing safe use in systems with catalytic converters and DPF without risk of contamination. When selecting a product on xenum.ua you receive a synthetic formula optimized to the requirements of MB 236.21, guaranteeing stable torque transmission, reduced fuel consumption and extended transmission service life.
