I am wondering if anyone knows about the summer gas formulation here in NJ. IS ethanol required as an additive or not? I bought some Shell the other day that has the sticker "may contain up to 10% ethanol" but so far doing 52MPG. I want to urge everyone to write their reps in congress and the senate to : 1- eliminate the ethanol mandate 2- kill the suspension of the gas tax that's being talked up. Every penny is needed to invest in transportation infrastructure. Plus we need to continue encourage conservation. Thanks Barbara
