Ahhhh....I figured it out.
Bucees is selling isobutanol (ethanol free) gas from Gevo. Since they are using corn to produce it the EPA has certified it as renewable source like ethanol gas. The stated benefit of isobutanol is it does not have an affinity to water (hydroscopic) like ethanol. I agree it is less hydroscopic but all alcohol attract water to some extent more than plain old dinosaur fart carbon compounds. The other stated benefit is it produces more power than ethanol gas but still less than dinosaur fart gas. I figured it would still have some concerns with destorying fuel lines, seals, etc but it appears several airlines have used it already. With that being the case Im sure numerous studies have been done to prove there is no issues there.http://ir.gevo.com/mobile.view?c=238618 ... id=2221415
My final thought...definetly better than ethanol gas for boat motors, small engines, etc but not as good as the old stuff.
