MB 236.8

MB 236.8 is the official Mercedes‑Benz technical specification for automatic transmission fluids, developed to ensure stable operation of modern multi‑speed gearboxes, including 7‑ and 9‑speed transmissions (7G‑Tronic, 9G‑Tronic) and DCT in passenger and commercial models. The specification requires high viscosity at low temperatures (V‑grade 6) and oxidation stability, which guarantees quick clutch engagement, long‑lasting wear protection and prevention of deposit formation in hydraulic channels. MB 236.8 provides low micro‑mechanical abrasiveness, high oxidation resistance and controlled thermal expansion, allowing optimal system pressure to be maintained during intensive loads and elevated temperatures. This approved fluid is compatible with Mercedes transmission electronic control systems, including adaptive shift algorithms, and does not require special SAPS additives, as it is not used in the engine. When choosing XENUM oil marked MB 236.8, you receive a product that meets all Daimler requirements for gear‑wheel, friction element and seal protection, delivering smooth gear shifts and extended transmission life.
