Freeway about 12-14.Basically this ^ what Daniel said though I actually seem to do a little better around town. But maybe he engages the full 6.9 effect more than I do. Best I ever did on the highway was 15 mpg. That was with a tailwind and constant-but-gentle continental downslope from Colorado to Iowa.
