Development of a method for obtaining import-substituting greases based on regenerated synthetic motor oils of Uzbekistan

The purpose of the study is to increase the efficiency of using used engine oils as a dispersion medium for plastic lubricants. It has been established that the removal of resins, carbenes, carbides and asphaltenes from used synthetic motor oils makes it possible to obtain an oil base close to commercial base oils in terms of basic characteristics; refined oils also have a high margin of operational properties. The composition of lubricants for analogues of Lithol-24 and Solid oil-Zh based on refined used engine oils has been determined. Anticorrosive, adhesive and strength properties of lubricant compositions are considered
