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 rspective applications. The third row is exclusive to SAE 80W-90 viscosity.

AMSOIL Severe Gear 75W-90 (SVO) 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 convential 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.

AMSOIL Severe Gear Synthetic Off-Road and Drag Racing Gear Lubricant SAE 190 (SRN) & SAE 250 (SRT) are formulated for severe racing conditions and other applications subject to extreme shock loading and pressures.
