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.
Product
Code: FGR
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:

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 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 Truck, Commercial Equipment |
Follow the
OEM drain interval (miles or hours) for synthetic
oil up to 500,000 miles. Otherwise, drain at twice
the OEM interval for conventional oil. |
Follow the
OEM drain interval (miles or hours) for synthetic
oil. 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.
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.

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. |
