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 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.

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

| Heavy Duty Class 8 Line

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.
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-140) provides superior performance and
replaces competitors’ 75W-140, 80W- 140 and 85W-140 gear oils. Use where these viscosities are
required by OEMs and where maximum viscosity protection is needed for extreme severe-duty
applications.
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.
