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 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, 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.

Drain at

manual, whichever is longer |
Drain at

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-110) provides superior performance and replaces
competitors’ 75W-110, 75W- 90 and 80W-90 gear oils. It delivers
better viscosity protection than SEVERE GEAR 75W-90 and better
fuel efficiency than SEVERE GEAR 75W-140.
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.
