Nowadays search of ways of obtainment new, more effective depressants for base oils is especially actual. Action of pour-point depressants is reduced to their influence on processes of crystallisation and structurizations of firm, first of all, paraffin hydrocarbons. In the given work we investigated depressants influence on some physical and chemical properties of oil distillates of the Kumkol deposit on the basis of the oil waste and a waste of oil-fatty industries. Concentration of entered additives and efficiency of their action depend on temperature of input of an additive, structure and quantity of paraffinic hydrocarbons, the asphaltenes and pitches maintenance, and also their ratio.
