MB 236.3

Approval MB 236.3 is a technical requirement from Mercedes‑Benz for automatic transmission fluids, developed to ensure stable viscosity, high oxidation resistance, low foaming, and effective wear protection under high‑temperature conditions. The specification is targeted at passenger and commercial Mercedes‑Benz vehicles equipped with 7G‑Tronic, 9G‑Tronic, as well as dual‑clutch (DCT) and conventional automatic transmissions that operate with gasoline and diesel engines. MB 236.3 requires a synthetic base with a viscosity of approximately 5.5 cSt at 100 °C and special friction additives that guarantee smooth and rapid gear shifts without excessive wear of valve and friction elements. The fluid is compatible with oil filters and transmission cooling systems, and also meets the requirements for seal protection and durability of hanging components. When you choose XENUM products bearing the MB 236.3 mark, you receive a fluid that complies with the original Mercedes‑Benz standards and provides optimal performance and reliability for your automatic gearbox.
