i would love to hear your findings pete, but there must be a downside, no? like eating seals or something? i'm pretty sure that it's not good to run alcohol fuel in an engine designed for gasoline. there's some modification that has to occur within the engine in order to facilitate longevity. i'd love to give it a try, but worry that i'd spend more in the long run than if i just put gas in. i have noticed that different gas stations produce better and worse gas milage. hess gas, for instance, smells like crap when i'm pumping and doesn't get me very far. sunoco on the other hand seems to give me the best bang or my buck. there is a certain amount of impurity that retail gas suppliers are allowd, and i wonder that sunoco as an example might dabble in acetone etc where hess seems to like sulfur.
