Viscosity index vi is an arbitrary measure for the change of viscosity with variations in temperature. The lower the greater, The vi the change of viscosity of the infused oil featuring temperature and vice versa. It serves the goal of characterize viscosity changes with relation to temperature in lubricating oil. The thickness of liquids decreases as temperature increases. The viscosity of a lubricant has a strong connection to to the capability to reduce the least, Friction. Generally viscous lubricant which still forces the two moving surfaces apart is desired. If the lubricant is too viscous, It will require a large level of power to move as in honey, If it is too thin, The surfaces will come in contact and friction will increase.
