SEVERE GEAR is designed for those who demand the best. Engineered with high film strength for high-load demands. Reduces friction and provides the ultimate protection against wear. Excels in extreme temperatures. Helps maintain efficiency and outperforms conventional gear oils. Excellent for all cars and trucks, but especially well-suited for towing, hauling, racing, commercial use or other severe duty.

Specifically engineered for maximum performance in severe-duty applications.

Maintains viscosity for long-lasting protection against metal-to-metal contact.

Proprietary AMSOIL additives form an iron-sulfide barrier coating on gear surfaces, providing the ultimate line of defense against wear, pitting and scoring.

Helps prevent "thermal runaway," a phenomenon caused by a lubricant’s inability to control friction and increased heat under high-stress conditions.

Inhibits rapid lubricant degradation and component damage, helping equipment run better and last longer.

Delivers excellent performance in hot and cold temperature extremes.

Resists breakdown from high heat, preventing acids and carbon/varnish formation.

Wax-free construction improves cold-flow properties, improving fuel economy and cold-weather shifting.
