Gear oil is heavy oil, rated at 80 to 100 weight viscosity that is used in enclosed units containing gears. Industrial gear oils are multigrade lubricants containing sophisticated extreme pressure additives. The viscosity of the oil should be high enough to muffle gear teeth and protect against failure. The viscosity is selected based on the system's requirements. Viscosity is the most important property of gear oil. The rate of change of viscosity with temperature is called the viscosity index. The ability of oil to maintain a small viscosity differential over the operating range of gearbox provides a more consistent lubricating films to the gears and more predictable wear performance.

Gear oil performs a multitude of functions. They are designed to reduce friction and wear, act as heat transfer agents, and protect against corrosion and rust. They also contain additives to minimize oil oxidation, inhibit foaming and separate water readily.
