SEVERE GEAR® 75W-140



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 Bulletin for full details.

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.
SEVERE GEAR 75W-90 Synthetic Extreme-Pressure (EP) Gear Lube

Some gear lubes fail to meet basic low-temperature requirements. Mobil 1 75W-140 Gear Oil, for example, failed to meet the requirements of the industry standard2. SEVERE GEAR, on the other hand, delivers 20 percent more cold-temperature protection than the standard requires.



See the Product Data Bulletin for full details.

2Based upon results of samples of Mobil 1 75W-140 and Valvoline SynPower 75W-140 purchased in 2018 and tested in ASTM D2983 by an independent testing facility in May 2018. Samples sent blind to eliminate bias.

    Topping Off
    By  JEFF,  a  Verified Buyer  from  Oakford, IL  on  April 01, 2021

    Describe the issue

    I had put a Banks Diff cover on the rear end of my 2018 GMC 3500. I originally purchased 4 quart as that is what AMSoil said I needed. It was not quiet enough so I had to purchase an extra quart to top off my rear end fill. This is a great product and the love the packaging

    What a difference
    By  AUSTIN,  a  Verified Buyer  from  Upstate New York  on  March 31, 2021

    Describe the issue

    After reading all the positive reviews about amsoil products I decided to give some a try myself. I am frequently towing well over my trucks factory capacity. Severe gear was a must try! Immediately after changing my rear differential oil I noticed my 1 ton pick up seemed to roll down the road with less drag. I also noticed half a mile to the gallon improvement in fuel economy. Doesn't sound like much but boy does it add up with fuel prices the way they are today.
    Bottom Line
    Yes, I would recommend this to a friend.
