Ive got 1000 miles and I've seen about 13 mpg in mostly city driving and stop and go. When highway its up in the 17's. Been keeping out of the revs because of breakin for the most part but everyday I step into it a little. My E70 4.8 got about 14 for the same type of driving with 20.5 in freeway driving.
