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 domestic and foreign manufacturers
such as GM, Ford and Daimler Chrysler.
- Can also be used rear axles where API Service
GL-4 lubricant is recommended.

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 owners 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), 75W-110 (SVT) and 75W-140 (SVO) synthetic gear
lubes have a performance emphasis on the extreme pressure
and high heat of todays 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.
