AMSOIL 80W-90 Synthetic Gear Lube is a multi-functional product designed to surpass the requirements of equipment and automotive applications calling for an SAE 80W-90 viscosity grade. Formulated with wax-free synthetic base oils and high quality additives, AMSOIL 80W-90 Synthetic Gear Lube resists thermal breakdown. Its naturally high viscosity index and shear stable construction improves film strength and viscosity retention.

AMSOIL Synthetic 80W-90 Gear Lube prevents wear, resists heat, and protects gears. It lasts longer in service than conventional gear oils and increases equipment life.

AMSOIL Synthetic 80W-90 Gear Lube provides:

  • High Load Gear and Bearing Protection
  • Longer Oil and Equipment Life
  • Lower Maintenance Costs
  • Compatibility With Conventional and Synthetic Gear Lubes
  • Multi-functional for Multiple Applications

AMSOIL Synthetic 80W-90 Synthetic Gear Lube is recommended for use under various combinations of high-speed, shock loads, low speeds and high torque conditions. It is recommended for use in all light and heavy-duty, automotive, commercial or industrial applications requiring SAE 80W-90 EP gear lube. AMSOIL Synthetic 80W-90 Gear Lube replaces all conventional 80W-90 gear oils and exceeds the lubrication and performance requirements of front and rear differentials, transfer cases, transaxles, manual transmissions, oil lubricated wheel bearings, and steering gear boxes that require any of the following specifications:

  • API GL-5 & MT-1
  • MIL-PRF-2105E
  • Dana SHAES 234 (Formerly Eaton PS-037) for 250,000 miles
  • Arvin/Meritor 0-76D plus hypoid gear oil specifications from all domestic and foreign manufacturers such as GM, Ford and Daimler Chrysler.
  • Can also be used rear axles where API Service GL-4 lubricant is recommended.


AMSOIL has optimized gear lube performance for specific operating conditions. However, AMSOIL gear lubes are multi-functional and may be used in many different applications. This chart conveys the best AMSOIL recommendation based on product design and operating environment.

First row product recommendations offer superior performance in the respective applications. Second row product recommendations offer excellent performance in the respective applications. The third row is exclusive to SAE 80W-90 viscosity.

AMSOIL Severe Gear® 75W-90 (SVG), 75W-110 (SVT) and 75W-140 (SVO) synthetic gear lubes have a performance emphasis on the extreme pressure and high heat of today’s vehicle differentials.

AMSOIL Long Life 75W-90 (FGR) and 80W-140 (FGO) synthetic gear lubes have a performance emphasis on 500,000 mile extended drain intervals associated with larger sumps and lower operating temperatures of over-the-road truck differentials.

AMSOIL 75W-90 synthetic gear lubes will outperform conventional 80W-90 gear oils in all applications and may be used as a replacement.AMSOIL offers 80W-90 (AGL) synthetic gear lube for those customers requiring this specific viscosity grade.
