Despite the fact that the shale oil industry in Estonia is a century old, there is still too little data about the thermodynamic and transport properties of the fuel. Information about these properties is important in producing and handling the fuel and in environmental and safety analyses. The current article addresses this problem by presenting experimental viscosity data for the lighter portion of kukersite shale oil, often called shale gasoline. The data is for 23 narrow boiling fractions, and also shows the change in viscosity for portions of the gasoline with different average boiling points. Viscosities were measured over a range of temperatures, and equations were fit to the data to describe the temperature dependence of the viscosity. Correlations are also presented which can be used for predicting the viscosity of kukersite shale gasoline if its density at 20 °C is known.
