Purpose and Specifications

MOTUL HD 80W90 GL5/4 1L is a tough mineral-based transmission oil built for heavy-duty gearboxes, differentials, and transfer cases. It handles high loads at low speeds or moderate loads at high speeds, protecting against wear in temperatures from -27°C startup to 210°C max operation.

Key benefits:
