CHARACTERIZATION OF LUBRICATING OILS BY DIFFERENTIAL SCANNING CALORIMETRY

The oxidative stability of formulated lubricating oils, and virgin and re-refined lubricating base stocks, have been determined by high pressure differential scanning calorimetry. Data on the response of re-refined and virgin base stocks to fixed quantities of an additive have been obtained. They are indicative of the wide diversity of the substances in question. The results of these studies indicate that the induction period measurements yield important information on the response of base stocks to additive treatment which could be used in quality control for formulating lubricating oils. Further studies are, however, needed to obtain more definite conclusions.
