On the way out from Philly, I got 39 something in my plain Civic with no batteries. It's a 2011. ( I hate electric.) My 2009 did 42. Crushing disappointment. However, since June 2012 the air conditioner has been blasting. Did so every mile of this trip. Maybe that accounts for the diff... Young Daniel (Banjok) got pissed off at my mileage discussions. Guess his van, stuffed with the objects of his cluttered mind, didn't fair as efficiently.
