All fuel injected cars manufactured since 1982 have been Federally required to have Oxygen sensors. The University of Denver did a study that found Oxygenated fuels on average increase pollution, not reduce it, and the ratio of card that benefit from Oxygenated fuels have been dropping steadily, ever since Oxygen sensors were introduced, as older cars are retired. Oxygenated fuels _never_ helped carbuerated vehicles to burn cleaner. > MTBE causes more harm than good.

MTBE is actually a waste chemical from other chemical plant processing; it's strange that it (like fluoride, in toothpaste, a waste product of aluminum processing) was ever incorporated. There was a joke going around a while back that the Japanese had solved the emissions problem totally, and that the emissions we see from cards today are actually them disposing of their remaining atmospheric pollution by shipping it over in cannisters as part of new vehicles, to release it slowly over the lifetime of the otherwise completely clean-burning vehicle. 8-) 8-).
