I drive pretty spirited... as possible and safely of course... 45 everywhere, but I dony go into Virginia's reckless driving range. (already got off easy once...) So 55 almost everywhere (given the space, and a good spot; feeling up that powerband, ya feel?), stop n' go with all the traffic and a full tank of 93 equates to usually 296 miles on a tank purely city driving ... maybe that'll change in the winter. Math makes it scary.. haha...........
smiles per gallon.
I know with the drive back from BPC I filled up once for safe measure, and when I was crusing at 75 or whatever through NC, I was in the low 400s for a full tank? Cloudy memory, sorry! But this is purely my experience... no catalytic converters in my exhaust. IDK what you're running... Also a 6M/T.
