What additives are in gasoline, and why are they in there?

Ethanol and methyl,t-butyl ether are common additives found in gasoline. These oxygenated additives are supposed to provide a "cleaner" burning gasoline -- that is, an exhaust that contains less Volatile Organic Compounds (VOC's). The significant efficacy of these additives has not been universally accepted, however. In addition, gasoline formulations containing these additives are not used nationwide. They are primarily found in areas designated by the Environmental Protection Agency as "high risk" atmospheric pollution areas. While difficult to quantify, the data one way or the other, in these areas is "mixed". This probably means that the pollution problem is much more complicated than simply the formulation of the fuel.
