This paper summarizes the study of the effects of oil formulation on fuel consumption using Japanese diesel engines and vehicles. Several test techniques are described for screening fuel-efficient diesel engine oils. A diesel engine oil formulated with the optimized combination of detergent-inhibitor package and friction modifier (borate), and multigraded to 10W-30, proved to exhibit the maximum fuel economy and to pass requirements for CD quality. The improvements demonstrated in dynamometer engine tests have been confirmed in extensive field testing.
