Abstract: the study of the impact of products generated during the preliminary thermostating on the pro-cesses occurring during the oxidation of engine oil and on anti-wear properties has a scientific and practical importance. For this purpose, a set of instruments was used including: a device for testing the heat resistance of oils in the temperature range from 160 to 300°C; photometric device for direct photometry; a device for deter-mining thermal and oxidative stability; low-volume viscometer; a device for testing friction materials; digital microscope; laboratory scales, allowing to determine the optical properties, kinematic viscosity, evaporation and anti-wear properties of oxidized and thermostatically controlled oils. This paper presents the results of a study of the effect of the products of temperature decomposition and pre-liminary thermostating on the anti-wear properties of Lukoil Standard 10W-40 SF / CC mineral engine oil. The effect of preliminary thermostating on antiwear properties has been determined, optimal temperature values of preliminary thermostating have been selected at which there is an increase in anti-wear properties when compar-ing thermostated engine oils at certain temperatures and commercial oil that has not been exposed to temperature impact.5 figures. 11 sources
