Severe Gear® Synthetic Off-Road and Drag Racing
Gear Lubricant SAE 190
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.
