FORD WSS-M2C192-A

Specification FORD WSS‑M2C192‑A defines the requirements for transmission oil for heavy mechanical gearboxes installed in Ford trucks and off‑road models. It calls for a viscosity of 75W‑140, high oxidation resistance, wear protection under extreme loads, and ensures stable operation of synchronizers and gears across a wide temperature range. Oils that meet this standard have low mineral content, high anti‑wear (EP) and satisfy compatibility requirements with metal and synthetic bearings, without affecting DPF systems or catalysts. The specification is targeted at diesel and gasoline engines with manual gearboxes up to 7,5 л, including models F‑150, Ranger, Transit and heavy commercial platforms. Using oil approved under WSS‑M2C192‑A guarantees compliance with Ford warranty conditions and extends transmission service life, and is also compatible with newer Ford specifications that retain the same viscosity and EP‑additive requirements.
