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 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.

    A superior gear lubricant
    By  Grease Monkey,  a  Verified Buyer  from  Grand Haven, MI  on  October 27, 2024
    I've used Amsoil in every one of my rear differentials since MY 2000. I have changed each of my vehicles rear axles into limited slip axles using an Eaton Truetrac and Amsoil severe gear has performed flawlessly in each one with no excessive slippage or grabbing. This differential oil is superior to any I've used in the past. I've used it in vehicles that were driven over 3500 mikes a month tomy current vehicle that rarely gets driven 3000 miles in 6 months and it's performed flawlessly.
    Bottom Line
    Yes, I would recommend this to a friend.

    I've always used Amsoil oil , spend a little more for exceptional products. Will always use Amsoil in all my vehicles. When you go to dealer and or mechanic they use basic oils, that's why I change my own, I know what's going in the engine

    Yes, I would recommend this to a friend.

    Not For 2020 or Newer GM Trucks.
    By  CORY,  a  Verified Buyer  on  July 30, 2024
    This product is not compatible with GM limited slip rear differentials. Change the rear end fluid in my 2021 GMC 2500 HD and used Amsoils 75w-90. It ruined the limited slip clutch in my rear end. Do not risk it, you must use the limited slip additive with this gear oil. Very disappointed.
    Bottom Line
    No, I would not recommend this to a friend.

    Amsoil marine oil
    By  JOHN,  a  Verified Buyer  from  Canada  on  June 23, 2024
    I hardly ever write reviews, but this one has been earned. I have used amsoil marine engine oil and gear lube since new in my 2011 Yamaha f40. It’s on a 20 ft work boat and if it’s not hulling materials to islands or pushing a barge with landscape materials and excavators the kids would be using it for waterskiing. It has had a tough life and still runs flawlessly after 14 years day in and day out all summer long. Engine and gear oils still come out clean after all these years I’d highly recommend amsoil marine oils.
    Bottom Line
    Yes, I would recommend this to a friend.
