This book reviews a draft report from the federal government that assesses the effects of oxygenated gasoline on public health, air quality, fuel economy, engine performance, and water quality. In addition to evaluating the scientific basis of the report, the book identifies research needed to better understand the impacts of oxygenated fuels. Methyl tertiary-butyl ether (MTBE), which is intended to reduce carbon monoxide pollution during winter, is the most commonly used additive in the federal oxygenated fuels program. MTBE has been implicated in complaints by the public of headaches, coughs, and nausea. Other questions have been raised about reduced fuel economy and engine performance and pollution of ground water due to the use of MTBE in gasoline. The book provides conclusions and recommendations about each major topic addressed in the government's report.
