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.
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 )-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.

manual or the Original Equipment Manufacturer (OEM) to establish
the application, NORMAL or SEVERE.

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.
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.
