If viscosity of water is lower than that of oil, why is water not used as a lubricant instead of oil?

Expert Answer:

Since water is less viscous, so it will be too thin, and when the surfaces will rub, the friction will increase, whereas oil is more viscous than water so it is not that thin and hence when two surfaces rub, it reduces the friction.
