AMSOIL’s SEVERE GEAR® 100% Synthetic Extreme-Pressure (EP) Gear Lube was developed by the company’s forward-thinking scientists to mitigate the effects of “thermal runaway,” the buildup of excessive heat and friction produced by an inadequate lubricant under extreme situations.

SEVERE GEAR® represents fifty years of research and development into the perfect synthetic gear oil. These heavy duty GL-5 gear lubricants use ingredients that are exclusive to AMSOIL. These additives help to produce an iron-sulfide barrier layer on gear surfaces, which provides the best possible protection against wear, scoring, and pitting.

AMSOIL 100% synthetic gear oils, in contrast to conventional gear oils, do not include the molecular abnormalities and contaminants that are intrinsic to conventional gear lubricants. AMSOIL’s SEVERE GEAR only utilizes 100% pure synthetic base lubricants with uniform molecular structures. These one-of-a-kind synthetic oils have qualities that traditional lubricants just cannot match, such as superior performance at very high temperatures, protection against wear, and increased fuel economy.
