Analytical data for 2,725 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 49 companies, large and small, which manufacture and supply gasoline. These data are tabulated by groups according to brands (unlabeled) and grades for 17 marketing areas and districts into which the country is divided. A map, included in this report, shows marketing areas, districts, and sampling locations. The report also includes charts indicating the trends of selected properties of motor fuels since 1946. Twelve octane-distribution-percent charts for areas 1, 2, 3, and 4 for unleaded, regular, and premium grades of gasoline are presented. The antiknock (octane) index ((R + M)/2) averages of gasolines sold in this country were 88.5, 89.6 and 95.0 for unleaded, regular, and premium grades of gasolines, respectively.
