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 Synthetic 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
MSOIL 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
