Get exceptional protection against spalling under extreme heat, pressure and torque operation.


Gears, differentials and their applications are more demanding now than ever before. On- and off-road trucks experience severe loading, whether it's carrying more freight or moving more. This is complicated by more powerful engines, higher operating temperatures and extended service intervals.

MAG 1® High Performance Gear Oils are specially formulated with the finest quality, hydrotreated, high viscosity index, paraffinic base oils and the most advanced and rigorously-tested additive system to deliver unsurpassed protection and performance.


  • 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
  • Extra resistance to thermal degradation provides superior protection against oxidation and deposit formation and significantly prolongs seal life
