In article the way of fractional division of oil on five fractions by means of installation of a columnar chromatography with two consistently applied difficult eluents is carried out. The carried-out analysis a method of a gas chromatography and research by means of luminescent spectroscopy showed that the fractions separated by means of a columnar chromatography studied in work oils have various component structure. It allows to speak about efficiency of the way of division applied in work with use corrected eluents.
