Differential oil is one of the important fluids used in modern cars for the lubrication of manual transmission and differentials. That’s why differential oil is also known as gear oil. As long as the gear oil is in good order, it allows the transmission to do its job safely and smoothly. Likewise, when it gets contaminated, it puts the differential components at risk and causes accelerated wear and tear. Since it is a vital lubrication fluid, so you need to be aware of the signs of a failing differential oil, so that you can replace the oil timely either on your own or by taking the help of a professional technician.
