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 heavy duty 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.

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

Drain at 100,000 miles of service
or according to the owner's manual, whichever is

Drain at 50,000 miles of service
or according to the owner's manual, whichever is
longer |
Heavy Duty
Class 8 Line Haul |
Follow the OEM drain interval
(miles or hours) for synthetic oil up to 500,000
miles or three years, whichever comes first.
Otherwise, drain at twice the OEM interval for
petroleum oil. |
Heavy
Duty
Off-Road Vocational |
Follow the OEM drain interval
(miles or hours) for synthetic oil up to 120,000
miles or one year, whichever comes first.
Otherwise, drain at twice the OEM interval for
petroleum 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.
