Alcohol makes for a sorry street fuel but a great racing fuel because it will handle up to 17/1 compression. It will make more power but requires twice the fuel to do it.

I would be more concerned with using high quality synthetic oil than what gas I'm using. The plating on these engines can be destroyed quick with cheap oil.
What kind of engine do you have?
