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 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.

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.
