Specifically Engineered for
500,000-Mile Service Life in Over-The-Road Trucks. AMSOIL
Long Life Synthetic Gear Lubes are extended drain gear lubes engineered specifically to
last several times longer and protect gears better than all conventional gear oils. These exclusive AMSOIL formulations of premium synthetic base oils and high performance additives resist acid, carbon and varnish formation from oxidative breakdown. Components run cleaner and last longer. AMSOIL
Long Life Synthetic Gear Lubes are shear stable and friction reducing. They maintain their viscosity during extended service for maximum wear control and they are fuel-efficient. The superior cold temperature fluidity and high temperature stability properties of AMSOIL
Long Life Synthetic Gear Lubes make them excellent for all-season use. Equipment lasts longer and maintenance costs are reduced with AMSOIL
Long Life Synthetic Gear Lubes.
Applications
AMSOIL
Long Life Synthetic Gear Lubes, in the correct viscosity grades, are recommended for all domestic and foreign applications such as over-the-road trucks, light, medium and heavyduty trucks, off-road equipment, commercial vehicles, motorhomes, autos, SUVs, emergency vehicles, busses, delivery/utility vehicles and tractors. Use AMSOIL
Extended Drain Synthetic Gear oils in differentials, manual transmissions or other gear applications where one or more of the following standards are specified: API GL-5 & MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton PS 037) for 250,000 miles, Dana SHAES 256 (Formerly Eaton PS-163) for 500,000 miles, Mack GO-J & GO-J+, Meritor 0-76N (75W-90) & 0-80 (80W-140), and Navistar TMS 6816 plus hypoid gear oil specifications from all foreign and domestic manufacturers such as GM, Ford and Daimler Chrysler. Can also be used in rear axles where API Service GL-4 lubricant is recommended.
Quick Facts:

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