The article is a review of ultrasonic influence on oil dispersions in order to improve their properties. The work discusses the mechanisms of acoustic influence, including its influence on the physical and chemical properties of oil. Particular attention is paid to the prospects of ultrasonic influence for improving the viscosity-temperature properties of oils, especially those with a high paraffin content. The mechanisms of the effect of ultrasound on oil dispersions and its influence on the structural and mechanical parameters of oils are also considered.
