Abstract: There are no qualified applications of the extracts oil distillate selective treatment, wherein the extracts contain surface active agents, which show antiwear, antioxidant and adhesive properties. The possibility of using solvent refining extracts oil distillate selective treatment as a component of lubricants dispersion medium was investigated. Rheological, low-temperature, oxidation and surface properties of solvent-refined extracts oil distillate selective treatment and its mixtures of mineral base oils were determined. It was established that at concentration 40 % by weight of the extract in a mixture of industrial oil tensile strength, oil separation characteristic, oxidation stability, low temperature properties, adhesion to metal surfaces and lubricity are increased. Greases based on the extracts have a lower cost in comparison with conventional lubricants based on oil mixtures
