Crude Oil Viscosity vs. Gravity

Viscosity at 20°C/68°F and 50°C/122°F for more than 120 crudes is shown as function of specific gravity@15°C/60°F.

The figure is based on information from more than 120 crude oil assays from BP, ExxonMobile and Statoil (2008 - 2017). The crudes are produced all over the world.
