Performance of an ethanol-gasoline blend in automobiles and light trucks

A description is given of a two million mile road test program, now being conducted, to evaluate the use of a 10 percent anhydrous ethanol--90 percent unleaded gasoline mixture as an automotive fuel. The testing also includes unleaded gasoline as a control fuel. The objectives of the program are to obtain quantitative data on fuel consumption, cylinder wear, and exhaust gas composition; and qualitative information on the condition of valves and valve seats, spark plugs, and the exhaust system. Some initial results are presented. (PMA)
