WebJul 27, 2024 · [0029] Viscosity Index (VI) is an empirical number used to measure the change in the base stock’s kinematic viscosity as a function of temperature. The higher the VI, the less relative change is in viscosity with temperature. High VI base stocks are desired for most of the lubricant applications, especially in multigrade automotive engine ...
