IMHO, running E-85 in a 'regular' gas engine modified to run Ethanol is a 'functional misapplication'. It 'works', but isn't optimal.

The engine in the article appears to be designed for Ethanol, with the capability to run gasoline,,, If it can bridge the '33% Delta' mentioned in the article, it would be a game changer.

Multiple locations sell E-85 here in Houston. Best price I've seen is $2.50/gal at Kroger. 87 is around $3, Diesel $3.50+
