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.

TYPICAL TECHNICAL PROPERTIES

AMSOIL Synthetic Gear Lubricant 80W-90 (AGL)
  NORMAL
SEVERE
Cars, SUV, Light & Medium
Duty Trucks
Drain at 100,000 miles of
service or according to the
owner’s manual, whichever is
longer
Drain at 50,000 miles of service
Heavy Duty Class 8 Line Haul
Follow the OEM drain interval (miles or hours) for synthetic oil up
to 250,000 miles or 3 years, whichever comes first. Otherwise,
drain at twice the OEM interval for conventional oil.
Heavy Duty Off-Road
Vocational
Follow the OEM drain interval (miles or hours) for synthetic oil up
to 120,000 miles or 1 year, whichever comes first. Otherwise,
drain at twice the OEM interval for conventional oil.
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 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.
