Basic oils produced from oil or obtained by the synthesis of monomers are generally chemically neutral. To improve the service properties of base motor oils, additive packages and active ingredients are introduced into it. The presence of anti-seize, anti-wear, and dispersing-stabilizing additives in a composition of commercial oil of a certain concentration of compounds of alkali metal salts changes its chemical activity [1]. Based on this, as a measure of service properties (anti-seize, anti-wear and dispersion-stabilizing properties (DSP)) of commercial motor oils can be used hydrogen indicator - pH. In the work, as an invariant estimate of the concentration of resource additives and service properties of commercial motor oils, the use of pH is considered. Correlation dependences of pH on BSP and viscosity of the studied motor oil are given.
