Vast majority city driving, I get a steady 25MPG, or about 350 miles on 14ish gallons. I've never ran it beyond 15 gallons, just because I'm a poon, and two days on the gas light is long enough.
One tank I ran 33MPG with about 200 highway miles and the other 200 or so in heavy city traffic.
Now, when I drive 1200 miles round trip to FOO FIGHTERS in Nashville, I'm shooting for less than 3 full tanks round trip.
