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 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 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.
