SEVERE GEAR is designed for those who demand the best. Engineered with high film strength for high-load demands. Reduces friction and provides the ultimate protection against wear. Excels in extreme temperatures. Helps maintain efficiency and outperforms conventional gear oils. Excellent for all cars and trucks, but especially well-suited for towing, hauling, racing, commercial use or other severe duty.

See the product data sheet for full details.

EXCELS IN TEMPERATURE EXTREMES

  • Delivers excellent performance in hot and cold temperature extremes.
  • Resists breakdown from high heat, preventing acids and carbon/varnish formation.
  • Wax-free construction improves cold-flow properties, improving fuel economy and cold-weather shifting.

MAXIMUM WEAR PROTECTION

  • Specifically engineered for maximum performance in severe-duty applications.
  • Maintains viscosity for long-lasting protection against metal-to-metal contact.
  • Proprietary AMSOIL additives form an iron-sulfide barrier coating on gear surfaces, providing the ultimate line of defense against wear, pitting and scoring.
  • Helps prevent "thermal runaway," a phenomenon caused by a lubricant’s inability to control friction and increased heat under high-stress conditions.
  • Inhibits rapid lubricant degradation and component damage, helping equipment run better and last longer.

    50 hour service on Kioti CK2620 hst
    By  SCOT,  a  Verified Buyer  from  Northern California   on  May 30, 2025
    I used this on the front axel of a Kioti CK 2620hst compact tractor for the 50 hour service. I’m not sure what the Kioti factory uses for the front axel but I’ve read several forums that claim they use hydrolic oil instead of gear oil. This gear oil along with 15w40 synthetic motor oil has my tractor running much quieter than it ran with factory provided products.
    Bottom Line
    Yes, I would recommend this to a friend.

    Good stuff
    By  JOSH,  a  Verified Buyer  from  Wisconsin  on  May 29, 2025
    I change all my fluids every 75k miles on my 1500 silverado and every 50k on my ram 2500. Neither has givin me any issue since I made the switch to amsoil. My silverado would lock and unlock the rear dif going down the road and almost ass soon as I switched to amsoil it stopped locking unnecessarily. It has been quiet leak free and we'll protected with Amsoil
    Bottom Line
    Yes, I would recommend this to a friend.
