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.

    Did a full replacement of fluids (drain and fill) with amsoil products. So diff, transfer case and atf on 2010 Toyota RAV4 V6. Products seem top notch. Everything running optimally. Very pleased in the performance of these products. If I don’t use factory fluid they have to be the best, hence Amsoil!
