Summary 1. Through the application of mathematical methods of experiment design and mathematical modeling in an investigation of the influence of calcium alkylsalicylate, calcium sulfonate, and a succinimide on the indices characterizing motor oil service properties, it has become possible to obtain a quantitative evaluation of the mutual influence of these additives on oil properties. 2. Of the additives investigated, the overbased calcium alkylsalicylate has the decisive influence on the thermal-oxidative stability of the oil. The predominant influence on oil dispersancy is that of the succinimide. 3. Mathematical methods have been used to demonstrate a rather high degree of correlation between the results on oil dispersancy as determined by means of the detergent potential and those based on the amounts of sediment on filters with different pore sizes. 4. Interactions among additives have a great influence on the relative viscosity change for the used oil in tests in the PZV unit. In the regions of additive concentrations represented by 0.8–1.5% SV, 4.4–5.6% PMSya, and 1–2.9% MASK, we observe a synergistic effect upon combining the calcium alkylsalicylate with the succinimide, and also on combining the calcium sulfonate with the succinimide.
