Severe Gear® SAE 250
Severe Gear® SAE 250
Engineered to Protect Hard-driven Racing Differentials Recommended for racing applications that require heavier-viscosity gear lubricants. Engineered specifically for the demands of severe racing conditions. Provides improved flow over conventional oils, reducing viscous drag and power loss. The ultimate line of defense against wear, pitting and scoring. Extends gear life.
AMSOIL Severe Gear EP Synthetic Racing Gear Lube is a premium-grade, extreme-pressure lubricant engineered specifically for the demands of severe racing conditions. It is formulated with shear-stable, heavy synthetic base oils for high film strength and extra-heavy treatments of additives. Severe Gear's synthetic formulation provides improved flow over conventional oils, reducing viscous drag and power loss. It cushions metal surfaces and absorbs the impact of moving parts while proprietary extreme-pressure additives form an iron-sulfide barrier on gear surfaces for the ultimate line of defense against wear, pitting and scoring.
Performance
AMSOIL Severe Gear EP Synthetic Racing Gear Lube is specifically engineered
for high-horsepower, high-torque conditions where centrifugal gear lube sling-off is
encountered. This tenacious formulation clings to gears and bearings for maximum
protection during shock loading, high G-forces and where pinion gears are installed at
steep angles. Severe Gear provides 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
Service Life
AMSOIL Severe Gear EP Synthetic SAE 190 and SAE 250
Racing 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 EP Synthetic SAE 190 and SAE 250
Racing Gear Lubricants are compatible with conventional and
synthetic automotive gear oils. Mixing AMSOIL gear oils with
other oils, however, will shorten the oil’s 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.
APPLICATIONS
AMSOIL Severe Gear EP Synthetic Racing Gear Lube is 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. 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.
