How can you measure viscosity
WebOil with a viscosity that does not change much between the temperatures of 40°C and 100°C has a higher VI than an oil with a relatively higher change in viscosity. The Viscosity Index Test (ASTM D 2270) is based on the kinematic viscosity of the oil at 40°C and 100°C, or 104°F and 212°F. Generally, a VI greater 95 is considered high.
