 SAE
Long Life Synthetic 80W-140 Gear Lube:
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.
Product
Code: FGO
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.

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
LONG LIFE SYNTHETIC GEAR LUBE 80W-140 replaces competitors'
80W-140 and 85W-140 viscosity grades.
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.
