AMSOIL Synthetic 75W-90 Severe Gear Lube delivers unbeatable protection and fuel economy. It has the film strength required to deliver all the protection heavy-duty and high-stress applications need in a fuel-saving viscosity grade. Recommended for use in all passenger vehicles, commercial trucks and race vehicles.

Provides superior lubrication, protection, and fuel economy in racing and commercial applications.

Be learly of buying oil from oil manufacturers who do not post their technical performance properties of their oil the way AMSOIL does! See below!


AMSOIL Synthetic Severe Gear Oil is a race-proven extreme pressure lubricant engineered to meet the severe high-load and high-temperature demands of contemporary race and commercial vehicle differentials and gear-oil equipped transmissions. It provides the superior friction, heat and load control demanded by race drivers, the superior fuel economy required by commercial vehicle operators and the superior performance sought by all motorists.

Friction Reduction and Fuel Economy

AMSOIL Synthetic Severe Gear Oil offers an exceptionally low coefficient of friction for superior power transfer, heat control and fuel economy.

In fact, independent testing shows class 8 vehicles with AMSOIL Series 2000 Synthetic 75W-90 Gear Oil in the differentials obtained up to 4.83 percent more mpg than vehicles equipped with another popular gear oil.

High Load and Extreme Pressure Performance

AMSOIL Synthetic Severe Gear Oil promotes long life for gears, including those subject to high loads and severe service. The superior film strength of its synthetic basestock ensures protection from wear for gears operating with full-film lubrication. Top-quality extreme pressure agents ensure protection from wear for gears operating without full-film lubrication.

High Temperature Performance

AMSOIL Synthetic Severe Gear Oil offer the thermal stability and durability, oxidation resistance and shear stability required for optimal protection in the hot environments in which race and commercial vehicle gears operate. Thermal stability and oxidation resistance keep gears and seals clean by inhibiting the heat-induced formation of sludge and deposits. Thermal durability protects gears from physical damage by preventing heat-induced failure of anti-wear chemistry. Shear stability helps prevent metal-to-metal contact and wear in high-temperature operations.

Low Temperature Protection

AMSOIL Synthetic Severe Gear Oil is ideally suited for low temperature applications. Its low temperature fluidity ensures excellent low temperature performance, protection and fuel economy.

Seal Compatibility and Rust and Foam Inhibition

AMSOIL Synthetic Severe Gear Oil forms a barrier on gear surfaces that seals out water to inhibit rust and corrosion. Foam inhibitors ensure protection in conditions that favor lubricant foaming and consequent metal-to-metal contact and wear.

AMSOIL Severe Synthetic Gear Oil has been shown to help seals perform better and last longer.


AMSOIL Synthetic Severe Gear Oil is Recommended for Applications Requiring the Following Specifications:

  • MIL-PRF-2105E
  • Dana Shaes 234 (formerly Eaton PS-037)
  • Mack GO-J

AMSOIL Severe Synthetic Gear Oil provides limited slip performance. Although generally not necessary, original equipment manufacturers' limited slip additives may be used in conjunction with AMSOIL Severe Synthetic Gear Oil.

NOTE: Most vehicle manufacturers recommend driving a vehicle in tight figure "8" patterns eight to ten times after changing limited slip lubricants.


AMSOIL Severe Synthetic Gear Oil is fully compatible with other fluids used in geared applications. To install AMSOIL Severe Synthetic Gear Oil, drain the fluid in the system and install the AMSOIL Series 2000 Synthetic Gear Oil.
