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
