I don't know the money trail on this stuff, but if the farmers are so up on it, let them run it exclusively. Next, 2 cents per gallon savings. If someone is such a tightwad, they will pump the E15, they deserve the consequences. 2 cents/gal at 20 gallons, saves 40 cents, really. I am going to get the gasoline shoppers also, drive 10 miles to save a penny a gallon????, buy 15 gallons, 15 cents. I had better step off the soapbox. My mind is going on a politcal rant and this is not the place. On a positive note, I add a shot of Marine Stabil to all my small engine gas, my older vehicles and any stored gasoline. I tried Sea Foam, but it turns too much trash loose, in the old engines.
