Synthetic Performance Oil...AMSOIL Gear Lube Recommendation Chart

AMSOIL Gear Lube Recommendation Chart

The AMSOIL Online Product Application Guide gives you fast, easy access to more than 20 years of vehicle data.

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

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

	NORMAL	SEVERE
Cars, SUV, Light & Medium Duty Trucks	Drain at 100,000 miles of service or according to the owner's manual, whichever is longer	Drain at 50,000 miles of service or according to the owner's manual, whichever is longer
Heavy Duty Class 8 Truck, Commercial Equipment	Follow the OEM drain interval (miles or hours) for synthetic oil up to 500,000 miles. Otherwise, drain at twice the OEM interval for conventional oil.	Follow the OEM drain interval (miles or hours) for synthetic oil. Otherwise, drain at twice the OEM interval for conventional oil.

For product service life in non-differential applications, consult owner's 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.

AMSOIL LONG LIFE SYNTHETIC GEAR LUBES are compatible with conventional gear oils, however mixing oils reduces the benefits and nullifies the extended service life recommendations.

AMSOIL LONG LIFE SYNTHETIC GEAR LUBES are compatible with most limited slip differentials. If limited slip differential chatter occurs, add AMSOIL Slip-Lock™ friction modifier additive.

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) 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.
