Severe Gear® Synthetic Off-Road and Drag Racing
Gear Lubricant SAE 250
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). An MSDS is available upon
request at 715-392-7101. Keep out of reach of children.
Don’t pollute. Return used oil to collection
centers.
