how will ethanol affect my fuel mileage ?

According to this

There's one store in the Spokane area selling E85. I'm about 50 miles from there, so "no."

The closest one to me in Idaho is in Lewiston, even further away. I'd use a whole tank just driving down there filling up and coming back, LOL

According to this, unless you are a tree hugger and "want to help th environment" the overall cost will be MORE not less than gas

My opinion? E85 is bullshit for street use. It is NOT evironmentally friendly as it takes more power and resources and GENERATES more pollution to produce it. Worse, especially now that vast areas of the U.S. are in a drought, growing bio mass for fuel takes resources AWAY from food production
