A method is presented for determining the optimum composition of engine oil formulations that consists of laboratory test methods appropriate for the characterization of the detergent-dispersant efficiency and a mathematical model for the evaluation of the data. The chosen mathematical correlation was found to be suited for determining the detergent dispersant efficiencies as a function of the composition of formulations consisting of alkenyl sucinimide, overbased Mg solphonate, overbased Ca sulphonate and zinc-dithiophosphate additives. The applicability of the method was proven by engine tests.
