Watch yourself. There are only 8 states that require pumps to be labeled that ethanol is used as an addative and Maryland is not one of them:Most stations will have stickers on the pumps if they are using E10 however it will vary from area to area depending on I believe population density. I live in PA and a number of pumps I've seen do not indicate E10 and it is still fairly rural where I'm at. I have seen one station that had a pump indicating E85 but that is usually for vehicles designed ast Flex fuel vehicles.
With the current setup of motor's I don't see how E anything will reduce emissions when you figure in you need to burn more of it to get the same distance and all the fossil fuels used to produce then transport ethanol.Not a whole lot of E85 stations out there. One in Annapolis and one in Rockville.
I would think the point is less emmisions not mileage..
