AMSOIL SEVERE GEAR Synthetic EP Gear Lube
AMSOIL SEVERE GEAR 100% Synthetic Extreme-Pressure Gear Lube is a premium-grade gear oil specifically engineered for maximum performance in severe-duty applications. It maintains its viscosity for long-lasting protection against metal-to-metal contact. Its proprietary AMSOIL additives form an iron-sulfide barrier coating on gear surfaces, providing the ultimate line of defense against wear, pitting and scoring.
SEVERE GEAR helps prevent thermal runaway — a phenomenon caused by a lubricant’s inability to control friction and increased heat under high-stress conditions. By controlling thermal runaway, it inhibits rapid lubricant degradation and component damage.
