Calculating the viscosity curve

The values shown are typical. You can fill in the names and viscosities (at 40°C y 100° C) for. When you press "Calculate" the graph will modify to show the curve for the four oils you have added. This will give you a general idea of the viscosity at your local temperatures.

The data you need should be available in the technical sheets of the oils you are considering.

Click here if you only know the viscosity of the oil at 40 (ISO viscosity grade) and the viscosity index.

Click here if you need to convert the oils from other viscosity systems (SUS, Engler, Redwood, etc.)

This is now working in all browsers, but you may have to adjust your zoom level or reset it to the default value to see the lower part.

Since the Ipad and other mobil devices do not run Flash applications, this tool will not work with them.
