When we removed the bowl, it had this clear hand sanitizer looking jelly formed and once it hit air, it evaporated and left little chunks of metal behind that it turned to liquid before and suspended. Nasty shit. the ONLY thing that was found to resist it, was chrome plated carb bodies, but the brass emulsion tubes and jetting still suffered.
It didnt do much to rubber or plastic part except dry them a bit.
Its a cheap alternative to race gas is about all its good for. More marketing assholes at work again with this product.
To expound on forrest's comment, 1 gallon of gasoline has about 124,000 BTU's of potential, where 1 gallon of E85 has about 96,000... Thats pretty drastic.
