Advanced Viscosity Calculator. Calculators The viscosity of oil changes with temperature, therefore multigrade oils were developed to provide protection across a range of operating temperatures. temperature %o viscosity tests were performed at one time, with two different viscometers. That’s why the viscosity grade on the oil … The difference between a 0W-30 and a 10W-30 is indicated by how well each flows at lower temperatures. 7 The interpolation calculator provided below is used to determine: Any mineral oil is supplied with the specification of kinematic viscosity values at two different temperatures, usually at 40°C and at 100°C (or at 100°F and at 210°F). For instance, an SAE 90 gear lube is comparable in viscosity to an SAE 50 or SAE 40 engine oil. Just put your values (either imperial or metrical) in the appropriate fields below and press ENTER. A fluid whose viscosity does not change much between these two temperatures will have a higher VI than a fluid whose viscosity change is greater. Variations in viscosity as a function of temperature … Eq. The main requirements for an engine oil are defined temperature-viscosity properties, protection against wear and corrosion, keeping the engine clean, holding particles like soot or abrasives in suspension, yield strength under compression and many more.
