Boo!!! I hate ethanol with a burning passion. The stuff destroys marine engines too, not to mention wreaking havoc on Jeeps. I know that if you have an engine failure in a Honda marine engine, they will test the fuel. If the fuel shows any traces of ethanol, they will void your warrantee. Luckily I have a station with ethanol free gas less than a mile from my house. Last fill up in the YJ was $3.51/gallon.
According to Honda's own website and limited warranty details on their site you are just spreading lies. Your warranty would be voided if you dumped E85 into your fuel tank but not any ethanol blends being sold as regular unleaded. That is sort of along the same lines as running diesel in a gasoline engine and trying to claim warranty for fuel related damages.....

Yes, and they were non-computer controlled, carbureted engines with the jetting increased to compensate for the alcohol over gasoline. The same holds true for racing engines running alcohol. The jets in the carburetor have to be much bigger (flowing more alcohol into the engine) to allow the engine to run alcohol over gasoline.
