Mineral oil viscosity temperature chart
WebTo determine the viscosity index of engine oils, the kinematic viscosity is measured at 40°C and 100°C, and these metrics are then compared to those of two reference oils. For example, traditional mineral oils have a viscosity index in the 95 - 100 range, while the VI of highly refined (hydrotreated) mineral oils typically go up to 120.

WebConventional industrial greases made with mineral oils in the order of 100 cSt viscosity at 40°C (104°F) can be used down to -25°F to -30°F (where viscosity of the oil phase reaches about 100,000 cSt) in most industrial … WebViscosity index. The viscosity index ( VI) is an arbitrary, unit-less measure of a fluid's change in viscosity relative to temperature change. It is mostly used to characterize the viscosity-temperature behavior of lubricating oils. The lower the VI, the more the viscosity is affected by changes in temperature.
WebFurthermore, the mineral oils' permittivity ranges from 2.1-2.5 [39] and dynamic viscosity in the range of approximately 80-100 cP [40]-both in room temperature.
