    Since different fluids contribute to the smooth operation of the automobile, thus without understanding the fluid dynamics, it might be impossible to tell what is actually dripping from the vehicle. When your vehicle is leaking something, it tells us about its malfunction simply by leaving portentous spots on the ground. Sometimes, due to the lack of knowledge, you turn a blind eye to the indication.
