Around here, Marathon is the most common major brand. Their refinery is just 30 miles from here. All their products, at least around here, says 10% ethanol. Casey's is the most prevalent cut-rate station around here and all their products are 10% ethanol. Ethanol couldn't compete if it weren't for the incentives and breaks. As a fledgeling industry, they should get a break but they should be using this time to improve their product to be competitive on its own merit. If not, it will just be a failure and waste of taxpayers money. Formulate it to produce octane and mileage.
