Abstract. The main trends in the use of modern greases are analyzed and the most promising ones are identified. The properties and structure of sulfonate greases with different alkalinity and their application areas are considered. The technologies and equipment used for the production of sulfonate greases with thickeners obtained by various methods are presented. Sulfonate greases can become «universal», due to their operational and physico-chemical characteristics. It is noted that a large number of studies of sulfonate greases have been conducted, but they are mainly related to the study of their structure and water absorption capacity. In this regard, additional studies of the protective and low-temperature properties of sulfonate greases based on various dispersed media, as well as the study of their tribological parameters at high temperatures, are needed.
