Motul 80W-90 – Gearbox & Differential Oil 1L Motul’s 80W-90 is a high-quality extreme pressure gearbox and differential oil, suitable for a wide range of mechanical transmissions including synchronised and non-synchronised gearboxes, transfer cases, and hypoid diffs.

This product replaces and supersedes the former Motul HD 80W-90 formulation and packaging — the oil specification and compatibility remain the same, with an updated name and part number for improved market coverage.
