MB 236.12

MB 236.12 is a Mercedes‑Benz technical specification that defines the requirements for hydraulic fluids for automatic and dual‑clutch transmissions (ATF/DSG) in the brand’s passenger and commercial vehicles. A fluid that meets MB 236.12 must have stable viscosity over a wide temperature range, high resistance to oxidation, protection against wear and corrosion, and a specific friction coefficient that ensures smooth operation of hydraulic systems, torque converters and braking elements. The specification is targeted at 7G‑Tronic, 9G‑Tronic, 5G‑Tronic, 6‑speed and 7‑speed DCT transmissions installed in C‑Class, E‑Class, S‑Class, GLE, Sprinter and other models. MB 236.12 does not impose special SAPS limits, so it is compatible with modern catalysts and DPF systems that are often used in Mercedes‑Benz diesel power units. When choosing XENUM oil that carries this approval, you get a product that meets all MB 236.12 requirements and at the same time satisfies newer requirements such as MB 236.14, without risking loss of compatibility.
