Product Description
AMSOIL SEVERE GEAR® Synthetic Extreme Pressure (EP) Lubricants are premium grade gear oils
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
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, buses, heavy equipment, 4X4s, tow trucks,
race cars, tractors, and motorhomes.

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

	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.

normal or severe synthetic oil service intervals. Where service intervals are unavailable, drain at
twice the interval for conventional oil.

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.

Note: AMSOIL does not support extended drain intervals where water contamination occurs. Check
and service the gear oil frequently when water contamination is possible.

Recommended for use in differentials, manual transmissions and other gear applications requiring
any of the following specifications: API GL-5, MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly
Eaton PS-037), Mack GO-J, or the differential (hypoid) gear oil specifications from all domestic and
foreign manufacturers such as GM, Ford and Daimler Chrysler. Can also be used in axles where an
API GL-4 lubricant is recommended.

AMSOIL SEVERE GEAR® (75W-90) provides superior performance and replaces competitors’ 75W-
90 and 80W-90 gear oils. It delivers the best fuel efficiency and cold temperature performance of the
SEVERE GEAR oils.

AMSOIL SEVERE GEAR® is compatible with conventional and synthetic gear oils. Mixing AMSOIL
gear oils with other oils, however, will shorten the oil life expectancy and reduce the performance
benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
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.
