Particularly recommended for recent mechanical gearboxes.All mechanical transmissions, synchronized or non-synchronized gearboxes, gearbox/axle, transfer case or hypoid axles without limited slip operating with shocks, under heavy loads and low rotation speeds or moderate loads and high rotation speeds, requiring an API GL-4 and SAE 75W gear oil. Also suitable for some “hard” or noisy gearboxes. Some manual gearboxes are not designed to use this type of low-viscosity transmission lubricant, before use, always consult the vehicle maintenance manual.
