IGH 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.
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.
For product service life in differentials, consult your owner’s manual or the Original Equipment Manufacturer (OEM) to establish the application, NORMAL or SEVERE.

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), 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.
