“Formulated for severe racing conditions and other applications subject to extreme shock loading and pressures. AMSOIL Severe Gear® Synthetic SAE 250 Gear Lubricant is a premium grade, extreme pressure gear lube engineered specifically for the demands of the most severe racing conditions. It is formulated with shear stable, heavy synthetic base oils for “high film strength” and extra heavy treatments of additives. Its high performance synthetic formulation provides improved flow over conventional oils, reducing viscous drag and power loss. Severe Gear® SAE 250 Gear Lube provide a tough 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.
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”

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.
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.
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.
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.
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.
