Severe Gear 75W90
& 75W110 & 75W140 Synthetic Extreme Pressure Lubricants:
Formulated for the severe operating conditions
of today’s pick-up trucks, SUVs, heavy equipment and other hard working vehicles are premium grade lubricants specifically
engineered for maximum performance in severe duty applications. These state-of-the-art AMSOIL formulations feature an exclusive
blend of high viscosity, shear stable synthetic base oils and an extra treatment of high-performance additives. AMSOIL Severe
Gear Synthetic EP Lubricants maintain their viscosity for long-lasting protection against metal-to-metal contact. The proprietary
AMSOIL additives form an iron-sulfide barrier coating on gear surfaces, providing the ultimate line of defense against wear,
pitting and scoring. AMSOIL Severe Gear lubricants help prevent “thermal runaway” — a phenomenon caused
by a lubricant’s inability to control friction and increased heat under high-stress conditions. By controlling thermal
runaway, AMSOIL Severe Gear Synthetic EP Lubricants inhibit rapid lubricant degradation and component damage. Equipment runs
better and lasts longer with AMSOIL Severe Gear Synthetic EP Lubricants.
Performance
AMSOIL SEVERE GEAR™
provides performance beyond that possible with conventional gear oil. These AMSOIL custom products offer superior gear and
bearing protection, better friction and heat reduction, increased efficiency and extended service life.

Temperature Extremes
AMSOIL SEVERE GEAR™
EP lubricants excel in hot and cold temperature extremes. By design, they resist breakdown from high heat, preventing acids
and carbon/varnish formation. Their waxfree construction also improves cold flow properties, improving fuel economy and cold
weather shifting.
Applications
AMSOIL SEVERE GEAR™ Synthetic EP Lubricants are excellent for severe
applications, such as towing, hauling, steep hill driving, commercial use, plowing, racing, off-road use, rapid acceleration,
frequent stop-and-go operation and high ambient temperatures.
Higher horsepower, towing and hauling capabilities
of modern vehicles make turbo diesel pick-ups, SUVs, vans and delivery/utility vehicles especially prone to severe service.
Other severe duty vehicles include light, medium and heavy-duty trucks, busses, heavy equipment, 4X4s, tow trucks, race cars,
tractors, and motorhomes.
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 or according to
the owner’s manual, whichever is longer
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 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.
Use in differentials, manual transmissions or other gear applications where one or more of the following standards are specified:
API GL-5 & MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton PS-037) for 250,000 miles, Mack GO-J, Arvin/Meritor 0-76N
(75W-90), plus hypoid gear oil specifications from all domestic and foreign manufacturers such as GM, Ford and Daimler Chrysler.
Can also be used in rear axles where API Service GL-4 lubricant is recommended.
AMSOIL SEVERE GEAR™ (75W-90)
replaces competitors’ 75W-90 and 80W-90 viscosity grades.
Aftermarket oil additives, other than those specified
by AMSOIL, are not recommended for use with AMSOIL gear oils.
AMSOIL SEVERE GEAR™ is compatible with most
limited slip differentials. If limited slip differential chatter occurs, add AMSOIL Slip-Lock™ friction modifier additive.

Long Life Synthetic Gear Lubes SAE 75W-90 & 80W140:
Specifically
engineered for extended drain intervals up to 500,000 miles as set by equipment manufacturers for over-the-road trucks and
heavy equipment. Prevents wear and improves equipment life. Excellent "All Season" summer and winter performance. Outperforms
all conventional gear oils. Also excellent for passenger cars and trucks. Compatible with most limited-slip differentials.
Performance specifications include: API GL-5 & MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton PS-037) for 250,000 miles,
Dana SHAES 256 (Formerly Eaton PS-163) for 500,000 miles, Mack GO-J & GO-J+, Meritor 0-76N, and Navistar TMS 6816 plus hypoid
gear oil specifications from all domestic and foreign manufacturers such as GM, Ford and Daimler Chrysler. Can also be used
in rear axles where API Service GL-4 lubricant is recommended.
AMSOIL Long Life Synthetic Gear Lubes are extended drain
gear lubes engineered specifically to last several times longer and protect gears better than all conventional gear oils.
These exclusive AMSOIL formulations of premium synthetic base oils and high performance additives resist acid, carbon and
varnish formation from oxidative breakdown. Components run cleaner and last longer. AMSOIL Long Life Synthetic Gear Lubes
are shear stable and friction reducing. They maintain their viscosity during extended service for maximum wear control and
they are fuel-efficient. The superior cold temperature fluidity and high temperature stability properties of AMSOIL Long Life
Synthetic Gear Lubes make them excellent for all-season use. Equipment lasts longer and maintenance costs are reduced with
AMSOIL Long Life Synthetic Gear Lubes.
Applications
AMSOIL Long Life Synthetic Gear Lubes, in the correct viscosity
grades, are recommended for all domestic and foreign applications such as over-the-road trucks, light, medium and heavyduty
trucks, off-road equipment, commercial vehicles, motorhomes, autos, SUVs, emergency vehicles, busses, delivery/utility vehicles
and tractors.
Use AMSOIL Extended Drain Synthetic Gear oils in differentials, manual transmissions or other gear applications
where one or more of the following standards are specified: API GL-5 & MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton
PS-037) for 250,000 miles, Dana SHAES 256 (Formerly Eaton PS-163) for 500,000 miles, Mack GO-J & GO-J+, Meritor 0-76N, and
Navistar TMS 6816 plus hypoid gear oil specifications from all domestic and foreign manufacturers such as GM, Ford and Daimler

Improved Seal Life
AMSOIL LONG LIFE SYNTHETIC
GEAR LUBES are compatible with conventional gear oils, however mixing oils reduces the benefits and nullifies the extended
service life recommendations.
AMSOIL LONG LIFE SYNTHETIC GEAR LUBES are compatible with most limited slip differentials.
If limited slip differential chatter occurs, add AMSOIL Slip-Lock™ friction modifier additive.
AMSOIL LONG LIFE SYNTHETIC
GEAR LUBE 75W-90 replaces competitors' 75W-90 and 80W-90 viscosity grades.
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.
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.
