AMSOIL SEVERE GEAR¨ Synthetic Extreme Pressure (EP) Lubricants are premium grade gear oils specifically engineered for maximum performance in severe duty applications. These state-of-the-art AMSOIL formulations feature an exclusive blend of high viscosity, shear stable synthetic base oils and an extra treatment of high-performance additives. AMSOIL SEVERE GEAR¨ Synthetic EP Lubricants maintain their viscosity for long-lasting protection against metal-to-metal contact. The proprietary AMSOIL additives form an iron-sulfide barrier coating on gear surfaces, providing the ultimate line of defense against wear, pitting and scoring. AMSOIL SEVERE GEAR¨ lubricants help prevent Òthermal runawayÓ Ñ a phenomenon caused by a lubricantÕs inability to control friction and increased heat under high-stress conditions. By controlling thermal runaway, AMSOIL SEVERE GEAR¨ Synthetic EP Lubricants inhibit rapid lubricant degradation and component damage. Equipment runs better and lasts longer with AMSOIL SEVERE GEAR¨ Synthetic EP Lubricants.
