We arent buying all that much from them anyway. They are only our 3rd highest supplier, Canada and Mexico give us most of our gas. IIRC, we only get something like 17% from the middle east. We watched some documentary on it in Econ during school.
People dont run E85 to be cheaper, they run it to lessen our dependance on foriegn oil and be cleaner on the environment. A few of them would be doing it so they can run much higher boost levels everyday without worrying about knock
