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.

    Slippery stuff!
    By  Books,  a  Verified Buyer  from  MD  on  April 27, 2021

    Describe the issue

    This has to be the easiest Diff fluid change ever. Pull fill plug, pull drain plug (yes, in that order) cut the top of the spout off and squeeze the bag to fill untill it's full. Simple, not messy, easy. Amsoil is the best.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best gear oil on the market. Not sold on the bag yet, the end cap would be the only thing I would change. It did not fit in the areas I needed (Can-Am outlander Gear box/Diff).
    Bottom Line
    Yes, I would recommend this to a friend.
