Viscosity index calculators are used extensively in the petroleum industry to ensure that lubricants can perform consistently in a wide range of temperatures. This means that oils with a high VI will maintain their lubrication properties even at high temperatures. The higher the VI, the less the change in viscosity with temperature change. The VI calculator works by comparing the viscosity of the oil at two different temperatures, typically 40☌ and 100☌. It is an important parameter in determining the quality and performance of lubricants. Viscosity index (VI) calculator is a tool used to measure the rate of change in the viscosity of oil with changes in temperature.
