Gear oil EP90 is a type of industrial lubricant specifically designed for use in heavy-duty gearboxes and differentials. The "EP" in the name stands for "extreme pressure," indicating that this oil has additives that help it withstand the high pressures and shock loads experienced by gears in these types of applications. EP90 protects bearings and gear teeth during demanding operations and guards against rust and corrosion, even when not in use.
