A vehicle track test showed increased gasoline engine fuel economy under both cold start and warm engine conditions using combinations of selected engine oils and power train lubricants. The engine oils, automatic transmission fluids and rear axle lubricants were chosen based on engine dynamometer and road simulator screening test. Motored and fixed engine dynamometer test were used to evaluate engine oils on friction horsepower and fuel consumption. Other test were used to examine automatic transmission fluids and gear lubricants on fuel consumption, economy and efficiency. INTRODUCTION. SUMMARY OF RESULTS. ABSTRACT. DISCUSSION. Track Test.
