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.
