Unfortunately, chemists are less adept at keeping their literature indexed and on line than computer scientists. Here is the public page for the place that has this and similar papers archived, but their search engine is currently broken: http://www.cutr.eng.usf.edu/research/afitc/public.htm Here is what it does to your hoses and seals: http://cartalk.cars.com/Info/Cyberchumps/Questions/q242.html Using queries for "+denver +oxygenated" on Altavista, you can get about 566 hits, and search them down. Wes probably remembers the Denver study from the radio in Utah from around that time. > > Oxygenated fuel only works well with carb'd cars. > > After all I said above, I'd love a cite for this too. Aren't the > majority of new vehicles pretty much all fuel injected. My car, which gets 64 miles a gallon, is carbuerated, as was the Honda CRX-HF, which got 72 miles a gallon. Both have higher pollution output with Oxygenated fuels; I have the Dynamometer results (required in Pima County, Arizona) which prove this, as they are on a six month Oxygenation cycle, and my car was borderline, then it had a clean bill of health (my registration renewal straddled the Oxygenation period).
