FIELD: chemical industry. SUBSTANCE: lubricant comprises mineral and/or synthetic lubricating oil on hydrogenated substrate, fluoropolyether oil and organic or inorganic thickener. Weight ratio of lubricating oil to fluoropolyether oil to thickener is from 97:3 to 80:20, and weight ratio of fluoropolyether oil is from 95:5 to 60:40. Lubricant is prepared by mixing hydrogenated substrate with thickener and fluoropolyether oil, preferably in the form of fluorinated lubricant homogenizing the mixture at 20-50 C passing it through three-cylinder homonizer at least two times. EFFECT: prolonged service life and maximum working temperature of lubricant and improved lubricating properties of the lubricant. 14 cl, 1 dwg, 9 tbl
