This calculator will tell you the viscosity index of your oil so you can be sure it will. ASTM D2270 Viscosity index VI from free temperatures. Any mineral oil is supplied with the specification of kinematic viscosity values at two different temperatures usually at 40C and at 100C or at 100F and at 210F.Ĥ0C cSt mm²s Kin. You can determine the viscosity of water at a particular temperature using the water viscosity-to-temperature chart or by the interpolation method using the water viscosity. The viscosity of oils and base oils of lubricating greases from Klüber Lubrication can be determined by means of the known kinematic viscosity at 40 C and 100 C. Viscosity cSt mm²s 40C.Ī higher VI is important when your machine will experience a big change in operating temperatures. This information and all further technical advice is based. Viscosity changes with temperature and Viscosity Index VI tells you how much. The calculator on this site is for informative purposes only. You are trying to make 20W-50 oil I guess.
