MB 236.9

MB 236.9 is a Mercedes‑Benz technical specification for automatic transmission fluids that defines requirements for viscosity, oxidation stability, wear protection and seal compatibility. A fluid that meets MB 236.9 must have a high viscosity index (VI ≈ 150), low volatility, excellent oxidation resistance and anti‑foam properties, ensuring stable operation under high loads and temperature ranges. The specification is targeted at Mercedes‑Benz automatic gearboxes with 5‑, 7‑ and 9‑speed variants (e.g., 5G‑Tronic, 7G‑Tronic, 9G‑Tronic), installed in both gasoline and diesel engines, including turbocharged models. MB 236.9 does not impose special requirements for SAPS, DPF or catalysts, as it concerns only the transmission system, but the fluid is compatible with typical particulate filters in gearboxes. When selecting oil on xenum.ua, products marked MB 236.9 provide smooth gear shifts, minimal wear of hydraulic components and long‑lasting protection under intensive service conditions.
