I read in our local newspaper that the ethanol blended gasoline currently being sold is probably going to be increased to E-15. I know of only one gas station in my local area that sells pure gasoline. Is anyone on this site versed on the real facts associated with the use of E-10 AND E-15 ethanol blended gasoline. It looks like its going to be very difficult to find pure gasoline in the future. What are the real pro and con uses of the blend?
