Years ago I heard that E10 would dry up and prematurely ruin all neoprene seals, diaphrams, hoses, etc.
Interesting to see what a slight difference in BTUs means in terms of MPG.
The hose and gasket thing is no longer a problem since modern trucks and automobiles are now designed to run on alcohol blended fuel up 85% (E-85) so the components are designed with that in mind. My new F-150 has a Flex Fuel engine that can use E-85 but the owners manual states there is a drop in power and fuel economy by using the stuff. Keep in mind that an engine specifically designed to run on alcohol can produce significantly more power than a gasoline fueled engine of the same displacement, recall the alcohol dragsters from the mid 1960's until the 1990's.
Alky is here to stay so if you want to run it in a gas engine on an RC model you need to raise the compression ratio slightly by milling the head. Also, change the fuel air mixture to get the most power out of it. Doing this will actually soup it up.
