Engineered to Last Longer

AMSOIL synthetic gear oil is engineered to last longer, several times longer than conventional gear oils. With premium synthetic base oils and high-performance additives, gear oils resists acid, carbon and varnish formation from oxidative breakdown. The psi strength of non-synthetic gear lube is about 800-1000 lbs., but AMSOIL gear oils have a psi strength of 3000 lbs. virtually eliminated metal-to-metal gear contact. Components run with less heat buildup in normal and server operating environments.

These synthetic gear oils are shear-stable, reduce friction and run cleaner than conventional oils. They maintain viscosity during extended severe-service for maximum wear control and is fuel-efficient. The superior cold & high temperature stability makes AMSOIL gear oils are engineered to last longer and an excellent choice for all-season use. Excellent for all cars and trucks, but especially well-suited for towing, hauling, racing, commercial use or other severe duty.

Temperature Extremes

  • Excels in hot and cold temperature extremes.
  • Resists breakdown from high heat, preventing acids and carbon/varnish formation.
  • Wax-free construction also improves cold-flow properties, improving fuel economy and cold-weather shifting.
  • Delivers 20 percent more cold-temperature protection than required by the industry standard.

Customers choose AMSOIL Synthetic Gear Lubes for:

  • High Load gear and bearing protection
  • Protection from rust and corrosion
  • Better cold-weather shifting
  • Improved efficiency
  • Improved seal life
  • Extended service life applications
