The study objective is to analyze the effect of the performance properties of engine oils on reducing the wear of machine parts. The paper discusses the issues of changing the viscosity of oils, friction factor, mass and composition of wear micro particles during operation. Special attention is paid to the comparative analysis of the viscosity before and after oil operation, as well as to the study of the elemental composition of wear products. The work uses modern methods of tribological testing, spectral analysis and gravimetric control. The novelty of the research is in an integrated approach to assessing the performance characteristics of oils in real engine operating conditions and identifying a correlation between the physical and chemical properties of the oil and wear intensity. As a result, it is found out that the use of modern additives, as well as control of the viscosity and composition of oils, can significantly reduce the formation of wear particles and increase the service life of parts.
