Motor gasolines, winter 1978-79
Various refiners, motor manufacturers, and chemical companies collected 2,358 samples from service stations throughout the country. They analyzed the samples in their laboratories and submitted the data to the Bartlesville Energy Technology Center for study, necessary calculations, and compilation under a cooperative agreement between the Bartlesville Energy Technology Center (BETC) and the American Petroleum Institute (API). The samples represent the products of 52 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 gasoline sold in this country were 88.7, 89.6, and 94.2 unleaded, regular, and premium grades of gasolines, respectively.
