had a gas station open up about 1/2 mile from my house last fall and it has ethanol free 90 octane. I've filled up my gas cans with it, so no everything small motor I run is using ethanol free. Its cost almost as much as premium though which kinda sucks
would gas companies even put ethanol in their gas if they weren't pushed to do by the government?
Since much of annual corn production in the U.S. is sold for ethanol distillation,
my guess is it's probably a pretty big benefit for grain farmers and no doubt has been a farm saver for some.
