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-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.
HEALTH & SAFETY
This product is not expected to cause health concerns when used
for the intended application and according to the recommendations
in the Material Safety Data Sheet (MSDS). An MSDS is available
upon request at 715-392-7101 or on the
AMSOIL website. Keep Out of Reach of Children. Don’t
pollute. Return used oil to collection centers.
