Mineral transmission lubricant. This product was specifically developed for mechanical transmissions, synchronized or non-synchronized gearboxes, gearboxes with differentials, transfer cases, and hypoid differentials without limited-slip systems, subjected to shocks, heavy loads, and low RPMs, or moderate loads and high RPMs. Recommended for noisy gearboxes and/or gearboxes subjected to stresses that require compliance with API GL-4/GL-5 and MIL-L-2105D standards. This product withstands heavy loads and reduces transmission noise. Its formulation offers very high lubricating power to reduce friction and wear. This extreme pressure lubricant provides efficient anti-wear protection, and its formula contains anti-corrosion and anti-foaming agents. Its high-temperature viscosity grade (SAE 90) provides excellent oil film strength. This product is suitable for gaskets and seals of all types, as well as for light alloys ("yellow metals") used in many gearboxes.
