This link has been a life saver for me http://pure-gas.org/ They list, by state, every known station that sells Non-Ethanol fuel. They even have a KML file for google earth, which marks on the map the known Non-Ethanol fuel station in the U.S.
Scott - did you know about the Sunoco station @ 1805 Tamiami Trl S in Venice?
Bob you made me dig out my manual for my 97 and look,and it says(use of alcohol extended fuels is acceptable onlyif the alcohol content does not exceed 10% ethanol by volume)My2002 Yamaha kicker says the same,are you sure you read E15.
