Thanks for the realistic A-MPG report. I swear the mileage some here report makes me think they drive down hill all the time...I tend to use 91 or 93 interchangeably. Really its just what is available at the gas station when I stop. Anyway, I get roughly 18-20 in mostly city driving (woo D.C. traffic). On the highway on road trips I normally get about 32/33.
My '12 EX does a little better around town that what you state, but not by much.
L.A. and surrounding not much better traffic wise...
