MAG 1 high performance gear oil is specially formulated with only the finest quality, hydrotreated, high viscosity index, paraffinic base oils and the most advanced and rigorously-tested additive system to deliver top protection and performance. Protects better in the following critical performance areas exceptional protection against spalling, maintenance of viscosity, prevention of acid formation, resistance to thermal degradation, reduced foaming and reliable performance. Recommended for multi-purpose, extreme pressure applications including conventional differentials, gearboxes, limited slip rear axles, manual transmissions and hypoid gears in two- and four-wheel drive tractors, combines and other farm equipment, as well as four-wheel drive off-road vehicles and construction equipment. U.S.A. Only available for sale in the continental United States. Exceptional protection against spalling and other wear, especially under extreme heat, pressure and torque operation, ensures long equipment life Maintains viscosity , even under extreme operating temperatures, resulting in longer fluid life and reduced operating costs Prevents acid formation for superior protection against rust and corrosion Extra resistance to thermal degradation provides superior protection against oxidation and deposit formation and significantly prolongs seal life Reduced foaming ensures smooth, efficient operation and proper lubrication Highly reliable performance over a wide range of temperatures.
