PRODUCT DESCRIPTION
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.
AMSOIL Long Life Synthetic Gear Lubes provide:
- High Load Gear and Bearing Protection
- Reduced Operating Temperatures
- Rust and Corrosion Protection
- Better Cold Weather Shifting
- Improved Efficiency
- Improved Seal Life

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

| 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.
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.
AMSOIL LONG LIFE SYNTHETIC GEAR LUBE 75W-90 replaces
competitors' 75W-90 and 80W-90 viscosity grades. |
