Analytical data for 3,695 samples of motor gasoline, from service stations throughout the country, were collected and analyzed under agreement between the Bartlesville Energy Research Center and the American Petroleum Institute. The samples represent the products of 53 companies, large and small, who manufacture and supply gasoline. These data are tabulated by groups according to brands (unlabeled) and grades for 17 marketing areas (districts) into which the country is divided. A map, included in this report, shows marketing areas and sampling locations. The report also includes charts indicating the trends of selected properties of motor fuels since 1946 and three bar graphs illustrating the variations of octane numbers in the present survey by frequency for all samples represented. The average antiknock (octane) index ((R + M)/2) of gasolines sold in this country were 89.8, 95.3, and 88.2 for regular, premium, and unleaded grades of gasolines, respectively.
