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.
- 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,
buses, heavy equipment, 4X4s, tow trucks, race cars,
tractors, and motor homes.

oil up to 250,000 miles or
three years, whichever comes first. |

oil up to 120,000 miles or
three years, whichever comes first. |
Heavy Duty Off-Road |
Follow the OEM
drain interval (miles or hours) for synthetic

years, whichever comes first. |
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.
