Product 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.

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

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).
