The invention relates to lubricating oil for Dieselmotorenoele with a performance level API CC, mainly suitable for use in engines of long-bound vehicles. According to the invention, such an OEI consists of a mixture of lubricating oil refiners with known additives and a special detergent-inhibitor composition in which the equivalence ratio of sulfonate and phenolic groups plays a decisive role. This composition provides very good high temperature performance and minimizes wear from acidic combustion products.
