Gear Oils for Differentials and Transfer Cases

Gear oils for differentials and transfer cases are specialized lubricants designed for gear systems that transmit engine power to the vehicle's wheels. A differential is a mechanical device that allows the wheels on one axle to rotate at different speeds, which is necessary, for example, when turning. A transfer case is then a system that usually includes a differential and serves for final gearing and the distribution of torque to the wheels. In these devices, a so-called "hypoid gear set" is often used, whose gearing is designed in such a way that significant sliding friction and extreme pressures occur during engagement. Conventional gear oils would fail under such conditions and would not be able to prevent seizure and damage to the gear set. Therefore, these oils contain special additives, referred to as EP additives (from "Extreme Pressure"), which form a protective film on the tooth surface that resists high loads. When selecting oil, it is crucial to follow the vehicle manufacturer's specification, which determines both the viscosity grade according to the SAE standard (e.g., 75W-90) and the performance level, most commonly according to the API classification (e.g., API GL-5). This classification ensures that the oil contains a sufficient amount of EP additives for the protection of hypoid gears.
