The When the internal combustion engine is operated on friction surfaces, the processes of oxidation, temperature destruction and chemical reactions of metals with their products and additives proceed simultaneously. However, the dominant influence of one of the processes on the physico-chemical and anti-wear properties of oils has not been adequately studied. Therefore, the purpose of the present studies is to search for a new criterion that takes into account the optical properties of thermostated oil, viscosity index and antiwear properties. The experimental results of the empirical test of the thermooxidative stability of motor oils of various base bases, determined by the ratio of the product of optical density to the decimal logarithm of the viscosity index to the arithmetic mean of the wear spot diameter, are presented. It has been established that the base base of engine oils and test temperature has a different effect on the empirical criterion of thermooxidative stability.
