Yea 280 all city. My GF drives the 8 daily an her round trip with work is about 6 miles or less a day. I drove it around town a few times, but never saw any highway on that tank and the light JUST came on at 280 miles before filling it back up..
My GF also barely sees RPM higher than 5k from what I can tell though - I keep telling her to push the car more. Thats why I drive the hell out of it when I get a chance - keeps the carbon off
