Analytical data for 2,433 samples of motor gasoline, from service stations throughout the country, were collected and analyzed under agreement between the Bartlesville Energy Technology Center and the American Petroleum Institute. The samples represent the products of 50 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 in this report. The antiknock (octane) index ((R + M)/2) averages of gasolines sold in this country were 88.5, 89.5 and 94.3 for unleaded, regular, and premium grades of gasolines, respectively.
