Product Description
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 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.
- Superior Film Strength
- Controls Thermal Runaway
- Rust and Corrosion protection
- Reduced Operating Temperatures
- Improved Efficiency
- Longer Oil, Seal, & Equipment
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.
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 100,000 miles of

Drain at 50,000 miles of

| 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.
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.
AMSOIL SEVERE GEAR™ (75W-90)
replaces competitors’ 75W-90 and 80W-90 viscosity
grades.
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
