Product Overview

SEVERE GEAR® SAE 250



Use in API GL-5, hypoid gear applications that require higher-viscosity oil, including off-road race trucks, rock racers and crawlers, competition tractors, funny cars, dragsters and heavy equipment. Where limited-slip performance is required, use AMSOIL Slip Lock® limited-slip additive.

See the product data sheet for details.

PROTECTS AGAINST WEAR

  • Extra-heavy treatment of additives and shear-stable, heavy synthetic base oils promote increased film strength for maximum wear protection.
  • Cushions metal surfaces and absorbs impact of moving parts.
  • Proprietary extreme-pressure additives form an iron-sulfide barrier on gear surfaces for the ultimate line of defense against wear, pitting and scoring.

PROVIDES FAST PROTECTION

  • Does not contain waxes that solidify in the cold inherent to conventional oils, meaning it provides excellent fluidity despite its high viscosity to quickly reach gears and bearings at startup.
  • Superior fluidity reduces viscous drag and energy loss, helping drivers put maximum power to the ground.

CLINGS TENACIOUSLY TO PARTS

  • Specifically engineered for high-horsepower, high-torque conditions where centrifugal gear lube sling-off is encountered.
  • Tenacious formulation clings to gears and bearings for maximum protection during shock loading, high G-forces and when ring and pinion gears are run at steep angles.
  • Provides excellent reliability and helps extend gear life.

    SAE 250
    By  DUANE,  a  Verified Buyer  from  Oklahoma  on  April 23, 2023
    used this in a 2016 TRD 4x4 Tundra 5.7 Supercharged 100,000 miles on the motor There are a number of other things I have done to the Engine,Exhaust, suppression. I have used other Amsoil product in the gear box on my 2016 Tundra with no problem. I just wanted to try the new SAE 250 I also used this product in my transfer case. The one thing I noticed is both front & Rear differential along with the Transfer case are a lot quitter. And by the way anything the gear grease touch it won't come off. Thank you Amsoil
    Bottom Line
    Yes, I would recommend this to a friend.

    Good Stuff
    By  Paul,  a  Verified Buyer  from  Arkansas  on  April 07, 2022
    I've used Amsoil Severe Gear in race cars for a long time and have never had a failure due to lubrication (and believe that this product has actually made differentials last longer than standard lubes would have). So, when the differential in my Kia Sorento began humming a tune I figured that Severe Gear might help make the costly repair a little further off in the future. It's been a couple of months now and the noise had dramatically diminished. I'm confident that my differential's life has been extended...maybe even saved.
    Bottom Line
    Yes, I would recommend this to a friend.
