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.
