The development of lubricants modified with geofillers based on non-oxidized and oxidized (oxidates) industrial oil I -40A and PN-6 petroleum plasticizer is studied. Serpentenites and manganese dioxide are used as geofillers. Based on the results, a high-temperature antifriction lubricant with repair and recovery properties was obtained, which is a lubricating composition based on PN-6 petroleum plasticizer oxidate with a geofiller - serpentinite and a crystallizer – manganese dioxide. The developed lubricant contains an optimal amount of serpentinite - 0.3%; manganese dioxide – 0.05%; oxidate -99.65%. High-temperature lubricants based on oxidized oils (oxidates) and geo-fillers are recommended for use in high-temperature and high-loaded friction units of machine-building equipment, in sliding bearings of steam engines, transport trolleys used in brick firing and other equipment. The lubricants obtained as a result of the research increase the service life of the equipment due to their good lubricating properties under conditions of high loads and temperatures in friction units.
