MB 235.8

Approval MB 235.8 is a Mercedes‑Benz technical requirement for hydraulic fluids intended for electronic power steering (EPS) systems, automatic transmissions and other hydraulic components of the brand’s vehicles. The fluid must have low viscosity, high oxidation stability, wear protection and compatibility with seals and filters, ensuring long‑term operation without deposit formation. The specification covers passenger and commercial Mercedes‑Benz models, including new generations with electronically controlled power steering and multi‑stage automatic transmissions. A fluid that meets MB 235.8 contains no harmful SAPS and operates safely in catalyst‑equipped systems, however its primary role is to maintain hydraulic integrity, not DPF protection. When selecting XENUM products, such as the transmission oil X‑TRAN 75W90 GL5, you obtain full compliance with this approval, guaranteeing optimal steering response and smooth gear shifts under any operating conditions.
