The results of testing partially synthetic Total Quartz 10W-40 SL/CF motor oil for thermo-oxidative stability in terms of optical density, volatility and coefficient of thermo- oxidative stability are presented taking into account the thermal energy absorbed by the products of oxidation and evaporation. The linear dependences of the decimal logarithm of thermal energy absorbed by the products of oxidation and evaporation and the total thermal energy absorbed by these products from the decimal logarithm of the test time in the temperature range from 160 to 190 ° C are established. A graphical and analytical model is proposed for predicting the indicators of thermo-oxidative stability, determined by the dependence of the decimal logarithm of the thermal energy absorbed by the products of oxidation and evaporation on the temperature of thermostating.
