In this chapter the term “alcohol/gasoline” refers to fuels that are composed of mixing methanol or ethanol with unleaded gasoline in various proportions. The resultant blends are suitable for use as alternative automotive fuels that address, to some extent, environmental concerns and regulatory requirements. They are sometimes referred to in abbreviations, e.g., E20 is a fuel consisting of a mixture of 20% ethanol and 80% gasoline by volume; M85 is a mixture of 85% methanol and 15% gasoline; and MEG refers to a mixture containing 33% methanol, 60% ethanol, and 7% gasoline. In addition, “gasohol” is marketed in Europe and North America as a mixture of up to 10% ethanol in gasoline.
