FIELD: chemistry.
SUBSTANCE: invention relates to a lubricating oil composition containing base oil with sulphur content not higher than 300 ppm, an aspartic acid derivative and expoxidated ester compound, in which the amount of the aspartic acid derivative and epoxidated ester compound is each equal to 0.01-5 wt % in terms of the entire composition. The invention also relates to use of said lubricating composition as engine oil, turbine oil, compressor oil, hydraulic oil, transmission oil, oil for sliding friction units, bearing oil and calibration oil. The invention also relates to a method of improving lubrication by using the lubricating oil composition.
EFFECT: obtaining a lubricating oil composition which can inhibit corrosion and sludge formation, capable of saving a large amount of energy and characterised by high operating efficiency.
