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.
|
NORMAL
|
SEVERE
|
|
| Cars, SUV, Light 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 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 75W-90 replaces competitors'
75W-90 and 80W-90 viscosity grades.
