Due to the need to reduce environmental pollution caused by used petroleum products, sources for increasing the efficiency of their use are being sought. The simplest source of savings is extending the service life of lubricants. The article presents the directions of ongoing research in terms of the impact of the proposed solutions on the technical condition of the lubricated internal combustion engine.Proper oil selection should ensure adequate reliability and cost-effectiveness of the device’s operation, while a technically justified service life of the oil in the device should ensure maximum utilization of the oil’s quality potential, thereby reducing the demand for new lubricants and the burden on the environment from used oil products. Assessing the quality of lubricating oils involves the ability to determine the level to which the oil fulfills its basic functions in the device. It is also important to be able to predict changes in oil quality during operation depending on the initial quality of the oil and the spectrum of stresses acting upon it. For this, knowledge of the kinetics of lubricating oil aging and the values of limit state parameters during operation in the device is essential. (…)
