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.

NORMAL |
SEVERE |
| Cars, SUV, Light &
Medium Duty Trucks |
Drain at 100,000 miles
of service or according to the owners
manual, whichever is longer |
Drain at 50,000 miles of
service or according to the owners
manual, whichever is longer |
| Heavy Duty Class 8 Line
Haul |
Follow the
OEM drain interval (miles or hours) for
synthetic oil up to 250,000 miles or 3 years,
whichever comes first. Otherwise, drain
at twice the OEM interval for conventional
oil. |
| Heavy Duty Off-Road
Vocational |
Follow the
OEM drain interval (miles or hours) for
synthetic oil up to 120,000 miles or 1 year,
whichever comes first. 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.
