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, 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

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