It sounds funny but my oldest daughter lives SE of Houston and I went for a visit. Before I came back I filled up at a Shell station and it had a sticker on the pump saying this fuel "may" contain up to 10% ethanol. OK no problem '05 Chevy 2500HD w/6.0L normally lousy mileage, 14 mpg on the way down but 16 mpg on the way back. Is this a bad thing???
