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.

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 longer |
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.
