Hmm, I'm not sure but I bet my smart friend would knowViscosity of machine oil?
Viscosity indicates the ability to flow, the higher the viscosity number the slower is the flow rate and the oil is thicker. Automobile engines need fast slow rates on cold winter mornings to minimize wear due to friction.
It depends. Mechanical wristwatch oil is watery. Differential gear oil in your car is very thick. Crankcase oil changes viscosity with temperature.
