This paper discusses information relevant to the impact of the characteristics of gasoline on fuel economy of motor vehicles. In particular, the paper analyzes the impact of the density, volatility, octane rating, and cleanliness of gasoline, as well as the impact of its additives. It also studies the relationship between fuel characteristics, fuel metering, and fuel economy. Furthermore, the paper serves to help explain some of the differences that may be found between the results of the EPA fuel economy tests and the values observed by vehicle owners in normal service. /GMRL/
