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.
