The deviation of density and viscosity values of oil mixtures from those calculated according to the additivity rule has been examined. Mathematical models have been developed for determining the properties of mixtures with different compositions taking into account the group composition of the source components. Mixtures containing components with a high content of alkanes and a low content of arenes have been found to be characterized by extreme deviations of density towards the maximum and kinematic viscosity towards the minimum. The created models were validated and compared with existing methods of describing the oil physicochemical properties. An approach to the creation of optimal from a technological point of view formulation for compounding oil of different types is proposed.
