Motor gasolines, winter 1985-1986
Samples for this report were collected from service stations throughout the country and were analyzed in laboratories of various refiners, engine manufacturers, chemical companies, and research institutes. Analytical data for the 1516 motor gasoline and 189 motor gasoline/alcohol blend samples were submitted to the National Institute for Petroleum and Energy Research (NIPER), Bartlesville, Oklahoma, for reporting. This work is jointly funded by the American Petroleum Institute (API) and the United States Department of Energy (DOE), Bartlesville Project Office. The data are representative of the products of 64 marketers, large and small, which manufacture and supply gasoline. They are tabulated by groups according to brands (unlabeled) and grades for 17 marketing districts into which the country is divided. A map shows the marketing areas, districts, and sampling locations. The report includes trend charts of selected properties of motor fuels over the last fifteen years. Twelve octane distribution graphs for leaded and unleaded grades of gasoline are presented for areas 1, 2, 3, and 4. The average antiknock (octane) index (R + M)/2 of gasoline sold in the United States during December 1985, and January and February 1986 was 87.3 for unleaded below 90.0, 91.8 for unleaded 90.0 and above, and 88.8 for leaded below 93.0 grades of gasoline. Analyses of motor gasolines containing various alcohols are reported in separate tables. The average antiknock (octane) index (R + M)/2 of gasoline containing alcohols was 88.4 for unleaded below 90.0, 91.6 for unleaded 90.0 and above, and 90.0 for leaded below 93.0 grades of gasoline. 16 figs., 5 tabs.
