AMSOIL SAE 80W-90 Synthetic Gear Lube

* Abbreviated Version

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.

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 Severe Gear 75W-90 (SVG) and 75W-140 (SVO) synthetic gear lubes have a performance emphasis on the extreme pressure and high heat of todays vehicle differentials.

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 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.

AMSOIL 80W-90 SYNTHETIC GEAR LUBE is compatible with most limited slip differentials. If limited slip differential chatter occurs, add AMSOIL Slip-Lock friction modifier additive.

AMSOIL SYNTHETIC 80W-90 GEAR LUBE is compatible with synthetic and conventional gear oils, however mixing oils reduces the benefits and nullifies the extended service life recommendations.

Gear oils should be changed more frequently when operating vehicles or equipment in dusty or dirty conditions unless the gear system is properly sealed and equipped with membrane type breathers.

Note: AMSOIL does not support extended drain intervals where water contamination occurs. Check and service the gear oil frequently when water contamination is possible.

For product service life in non-differential applications, consult owners manual or the OEM for either normal or severe synthetic oil service intervals. Where service intervals are unavailable, drain at twice the interval for conventional oil.

For product service life in differentials, consult your owner's manual or the Original Equipment Manufacturer (OEM) to establish the application, NORMAL or SEVERE.
