have been used to undersaturated oil. The accuracy of models for investigated viscosity were applied to the acquired data set and a comprehensive error analysis was performed based on a comparison of the predicted value with the experimental value. The results obtained indicate, that modified Kartoatmodjo model is the best and accurate for saturated oil viscosity, while Beal's model is the best for undersaturated oils. The less AARE % was calculated 23.9% for saturated oil, and 21.9 % for
