PRODUCT
DESCRIPTION AMSOIL Severe Gear
Synthetic SAE 190 and
SAE 250 Gear Lubricants are premium grade,
extreme pressure gear lubes engineered
specifically for the demands of severe racing
conditions. They are formulated with shear
stable, heavy synthetic base oils for “high
film strength” and extra heavy treatments of
additives. Their synthetic formulations provide
improved flow over conventional oils, reducing
viscous drag and power loss. Severe Gear SAE
190 and
SAE 250 Gear Lubes provide a barrier
cushion between metal surfaces that absorbs
impact. AMSOIL proprietary extreme pressure
additives form an iron-sulfide barrier coating
on gear surfaces for the ultimate line of
defense against wear, pitting and scoring.
PERFORMANCE
AMSOIL Severe Gear Synthetic SAE 190 and
SAE 250 Gear Lubricants are specifically
engineered for high horsepower, high torque
conditions where centrifugal gear lube
sling-off is encountered. These tenacious
formulations cling to gears and bearings for
the best possible protection during shock
loading, high G-forces and where pinion gears
are installed at steep angles. Custom Severe
Gear Synthetic Gear Lubricants provide
exceptional reliability and extended gear
life.
• Protects gears from shock
loading and tire shake
• Resists sling-off from G-forces and high
speeds
• Clings to gears - high pinion style and
at steep angles
• Promotes cooler operating
temperatures
• Protects against rust and corrosion
• Extends gear and bearing
life
APPLICATIONS
AMSOIL Severe Gear Synthetic
SAE 190 and SAE
250 Gear Lubricants are excellent for
severe differential applications, including
off-road truck racing, rock racing, rock
crawling, tractor pulling, funny car racing and
dragster racing. Other severe duty applications
include heavy duty trucks and equipment where
increased lubricant film is necessary. These
oils are recommended for use in hypoid gear
differentials and other applications requiring
a high viscosity, API GL-5 gear lube. Where
limited slip performance is required, use
AMSOIL Slip-Lock® limited slip additive.

Service Life
AMSOIL Severe Gear Synthetic SAE 190 and
SAE 250 Gear Lubricants are intended
for severe racing and other applications
where extended drain intervals are not
beneficial. AMSOIL recommends changing the
lubricant as conditions dictate. Where
extended drain intervals are desired,
AMSOIL recommends monitoring by oil
analysis.
Mixing
AMSOIL
AMSOIL Severe Gear Synthetic SAE 190 and
SAE 250 Gear Lubricants are compatible
with conventional and synthetic automotive
gear oils. Mixing AMSOIL gear oils with
other oils, however, will shorten the oil
life expectancy and reduce the performance
benefits. Aftermarket oil additives, other
than those specified by AMSOIL, are not
recommended for use with AMSOIL gear
oils.
