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.
Health & Safety
This product is not expected to cause health concerns when used for
the intended application and according to the recommendations in the
Material Safety Data Sheet (MSDS). Keep out of
reach of children. Don’t pollute. Return used oil to collection centers.
