AMSOIL Synthetic 80W-90
Gear Lube (AGL)
AMSOIL Synthetic 80W-90 Gear Lube is a high
quality replacement for applications specifying SAE 80W-90
conventional gear lube. Synthetic construction provides
improved cold flow properties, high viscosity index and
heat resistance. Contains an over treat of high quality
additives, exceeding the minimum standards. Provides
excellent wear protection and long equipment life.
Performance specifications include: API GL-5 & MT-1,
MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton PS-037) for
250,000 miles, Mack GO-J, 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.

PRODUCT
DESCRIPTION AMSOIL 80W-90 Synthetic Gear
Lube is a multi-functional product designed to surpass the
requirements of equipment and automotive applications calling
for an SAE 80W-90 viscosity grade. Formulated with wax-free
synthetic base oils and high quality additives, AMSOIL 80W-90
Synthetic Gear Lube resists thermal breakdown. Its naturally
high viscosity index and shear stable construction improves
film strength and viscosity retention. AMSOIL Synthetic 80W-90
Gear Lube prevents wear, resists heat, and protects gears. It
lasts longer in service than conventional gear oils and
increases equipment life.
AMSOIL Synthetic 80W-90 Gear Lube
provides:
- High Load Gear and Bearing Protection
- Longer Oil and Equipment Life
- Lower Maintenance Costs
- Compatibility With Conventional and Synthetic Gear
Lubes
- Multi-functional for Multiple Applications
APPLICATIONS AMSOIL Synthetic 80W-90
Synthetic Gear Lube is recommended for use under various
combinations of high-speed, shock loads, low speeds and high
torque conditions. It is recommended for use in all light and
heavy-duty, automotive, commercial or industrial applications
requiring SAE 80W-90 EP gear lube. AMSOIL Synthetic 80W-90 Gear
Lube replaces all conventional 80W-90 gear oils and exceeds the
lubrication and performance requirements of front and rear
differentials, transfer cases, transaxles, manual
transmissions, oil lubricated wheel bearings, and steering gear
boxes that require any of the following specifications:
- API GL-5 & MT-1
- MIL-PRF-2105E
- Dana SHAES 234 (Formerly Eaton PS-037) for 250,000
miles
- MACK GO-J
- Arvin/Meritor 0-76D plus hypoid gear oil specifications
from all foreign or domestic manufacturers such as GM, Ford
and Daimler Chrysler.
- Can also be used 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

| Heavy Duty Class 8 Truck,
Commercial Equipment |
Follow the OEM drain interval (miles
or hours) for synthetic oil up to 250,000
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.
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 SYNTHETIC 80W-90 GEAR LUBE is
compatible with synthetic and conventional gear oils, however
mixing oils reduces the benefits and nullifies the extended
service life recommendations.
AMSOIL 80W-90 SYNTHETIC GEAR LUBE is
compatible with most limited slip differentials. If limited
slip differential chatter occurs, add AMSOIL Slip-Lock™
friction modifier additive.

AMSOIL has optimized gear lube performance for
specific operating conditions. However, AMSOIL gear lubes are
multi-functional and may be used in many different
applications. This chart conveys the best AMSOIL recommendation
based on product design and operating environment.
First row product recommendations offer
superior performance in the respective applications. Second row
product recommendations offer excellent performance in the
respective applications. The third row is exclusive to SAE
80W-90 viscosity.
AMSOIL Severe Gear™ 75W-90 (SVG) and 75W-140
(SVO) synthetic gear lubes have a performance emphasis on the
extreme pressure and high heat of today’s vehicle
differentials.
AMSOIL Long Life 75W-90 (FGR) and 80W-140 (FGO)
synthetic gear lubes have a performance emphasis on 500,000
mile extended drain intervals associated with larger sumps and
lower operating temperatures of over-the-road truck
differentials.
AMSOIL 75W-90 synthetic gear lubes will
outperform conventional 80W-90 gear oils in all applications
and may be used as a replacement.AMSOIL offers 80W-90 (AGL)
synthetic gear lube for those customers requiring this specific
viscosity grade.
