The possibilities of differential thermal analysis (DTA) in registering thermal conversions of organic compounds are such that this technique is quite suitable for use in the qualitative investigation of lubricating oils. Explains that based on the fact that the individual parameters of TG and DTG curves are subject to the additivity rule, an analogous tests was performed in application to DTA. Establishes that the basic parameters of the peaks of the DTA curves can be classed as additive indexes by using a methodological approach that includes successive thermal analysis of the original oil and its hydrocarbon groups obtained by liquid adsorption separation. Concludes that by correlating the parameters of the DTA peaks and indexes of hydrocarbon composition of lubricating oils, the development of new methodological variants that will expand the possibilities for the use of thermal analysis in qualitative characterization of oils can now be predicted.
