Boy, I would be very interested in your findings on the e10 fuel experiment. My father moored his 21 foot runabout boat with a Honda 150 outboard on it and had this bad habit of topping off the tanks with e10. He was always having problems with that engine running well until he had the mechanic drain the fuel tank and what we found was not pretty. The gas and alcohol had separated looked just like oil and vinegar. He kept a sample in a mason jar to show us. You could shake it up and set the jar down and the fuel would never re-combine with the alcohol. By this time some of the fuel was a few years old and my Dad was too cheap to buy the non alky fuel from the marina or a bottle of stabilizer either.
