I am curious if anyone has tried E-85 yet?!? I want to make sure my engine is well broken in before I use it, but it is tempting when it is always 50-75 cents less/gallon!
E85 is not supported on the 2012 Focus, it's "late availablity" right now. Don't put E85 gas in a Ford vehicle unless it has the "yellow" ring around the fuel filler.
