For the first five tanks of gas in the GS, it’s been mostly city driving, and I’ve been averaging 9.76L/100km, or 24 mpg — 3 mpg better than the EPA number in the U.S., but 1 mpg less than the Canadian rating.
However, with the latest tank I managed to get in a little more highway driving than usual, and had my best “score” yet:

(9.0L/100km translates into 26.1 mpg.)
