1. Why Differential Fluid Is Important
The differential in your car plays a crucial role in distributing engine power to the wheels, especially when turning. The differential fluid lubricates its gears, reducing friction and wear. Over time, this fluid can become contaminated or break down, leading to increased wear, overheating, or even failure of the differential. Regularly changing your differential fluid is key to maintaining smooth and efficient vehicle operation.
