Abstract
Obtained results were compared to those determined by a variety of methods in order to check the reliability of pseudo-component approach. Comparison of D20 predictions show that pseudo-component mixing rule exhibits similar accuracy as the best of the methods tested for the studied lubricating oil mixtures. Regarding to n20 predictions, the use of a function of refractive index as pseudo-component property, instead of refractive index, clearly improves the prediction accuracy. This modification yields deviations similar to those obtained by the most accurate of the methods tested for the analyzed lubricating oil mixtures. Pseudo-component approach presents as main advantage over tested correlations, that experimental information on refractive index or density are not required.
