As clean air and clean fuel issues become the focal point for state implementation plans, the issue of fuel quality and composition is now being addressed by the nation's automakers, environmentalists and state regulators. A review of the 1995 model year warranty statements from the nation's top three automakers reveals that all now recommend the use of reformulated gasoline and fuels containing oxygenates such as MTBE and ETBE. | ||

"Many gasolines are now blended that contribute to cleaner air, especially in those areas of the country where pollution levels are high. These new blends provide a cleaner burning fuel and some are referred to as reformulated gasoline. In areas of the country where carbon monoxide levels are high, gasolines are being treated with oxygenated materials such as MTBE, ETBE and ethanol. The use of gasoline blended with these materials also contributes to cleaner air. Chrysler Corporation supports these efforts toward cleaner air and recommends that you use these gasolines as they become available." | ||

"Several petroleum companies have announced the availability of reformulated fuels. These fuels are specially designed to further reduce the emissions from today's automobiles. More and more reformulated fuels will become available as refiners move to meet the new Clean Air Act requirements for 1995. We encourage our customers to use these fuels." | ||

"Many gasolines are now blended with materials called oxygenates. General Motors recommends that you use gasolines with these blending materials, such as MTBE and ethanol. By doing so, you can help clean the air, especially those parts of the country that have high carbon monoxide levels. In addition, some gasoline suppliers are now producing reformulated gasolines. These gasolines are specially designed to reduce vehicle emissions. General Motors recommends that you use reformulated gasoline. By doing so, you can help clean the air, especially in those parts of the country that have high ozone levels." | ||
