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,

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