236.93

Specification 236.93 – this is the official approval from Allison Transmission for automatic transmissions, which defines a comprehensive set of requirements for viscosity, thermal stability, wear and oxidation protection. Oil that meets 236.93 must have a kinematic viscosity at 100 °C in the range of 7.5‑9.5 cSt, high shear stability, low foam, and effective protection of friction elements, including brake discs and torque converter. This specification is aimed at heavy commercial and specialized vehicles – trucks, buses and construction equipment equipped with Allison automatic gearboxes (series 2000, 3000, 4000 and others). Since 236.93 contains no SAPS restrictions, it is suitable for transmissions without post‑catalytic systems, providing long‑lasting stable operation even under intensive loads.
