New Amsoil Severe Gear Viscosities for Racing

Note: This article was recovered from an earlier version of Technilube.com and republished to preserve useful information and site history. Some details, links, product information, terminology, and availability may reflect the original publication date.

AMSOIL has announced the addition of SAE 190 and SAE 250 Severe Gear Synthetic Gear Lubes to its powerful line of AMSOIL Severe Gear Extreme Pressure Synthetic Gear Lubes.  AMSOIL gear lubes feature an exclusive blend of high viscosity, shear stable synthetic base oils and an extra treatment of high-performance additives. They are engineered to protect gears better than conventional gear oils, resisting acid, carbon and varnish formation, oxidative breakdown and thermal runaway.

These two new viscosities have been specially engineered for severe differential applications including off-road and drag racing, and rock crawling. Their tenacious formulation clings to gear surfaces to prevent gear wear in extreme conditions. Below are more specifics:

Severe Gear® Synthetic Off-Road and Drag Racing Gear Lubricants:
SAE 190 and SAE 250

Formulated for severe racing conditions and other applications subject to extreme shock loading and pressures.

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.
