AMSOIL Recommended

AMSOIL Severe Gear
Synthetic Extreme Pressure (EP) Lubricants are premium grade lubricants
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 prevent
"thermal runaway" - a phenomenon caused by a lubricant's inability
to control friction and increased heat under high-stress conditions. By
preventing 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.
Use in differentials,
manual transmissions or other gear applications where one or more of the
following standards are specified: API GL-5 & MT-1, MIL-PRF-2105E, Dana
SHAES 234 (Formerly Eaton PS-037) for 250,000 miles, Mack GO-J, Arvin/Meritor
0-76N (75W-90) & 0-76M (75W-140), plus hypoid gear oil specifications from
all foreign and domestic manufacturers such as GM, Ford and Daimler Chrysler.
Can also be used in rear axles where API Service GL-4 lubricant is
recommended.
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, busses, heavy equipment, 4X4s,
tow trucks, race cars, tractors, and motorhomes.

Follow
the OEM drain interval (miles or hours) for synthetic oil up to 250,000
miles. Otherwise, drain at twice the OEM interval for conventional oil.

Follow
the OEM drain interval (miles or hours) for synthetic oil. Otherwise, drain

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.
AMSOIL SEVERE GEAR™ (75W-90) replaces competitors'
75W-90 and 80W-90 viscosity grades.
AMSOIL SEVERE GEAR™ is compatible with conventional
gear oils, however mixing oils reduces the benefits and nullifies the
extended service life recommendations.
AMSOIL SEVERE GEAR™ is compatible with most limited
slip differentials. If limited slip differential chatter occurs, add AMSOIL
Slip-Lock™ friction modifier additive.
Note: AMSOIL does not support extended
drain intervals where water contamination occurs. Check and service the gear
oil frequently when water contamination is possible.
