Without properly formulated automotive gear oils, limited-slip differentials can experience noise, vibration, and harshness, also called clutch chatter or squawking. When the clutch does not properly engage, it can cause gear grinding, shifter blocking, or a tendency for the car to creep forward, creating a safety concern. It can also create poor torque transfer, resulting in reduced power, increased friction, and potential component damage.
