The viscosity index, or VI, of lubricating oil is the main gauge of its performance. While lubricants reduce friction and wear between moving parts, their effectiveness mostly relies on maintaining an appropriate viscosity throughout a temperature range.The Viscosity ChallengeMost oils have changing viscosity with temperature. Heated, they thin out; cooled, they thicken. For machinery running in conditions with changing or extreme temperatures, this presents a problem. Should the oil thin too much, it might not provide enough lubri... more
