When I drive to and from work (lots of lights and stop signs), I get low 20 mpg's. I drove all interstate the other day at 78 or 79 mph and got 30 mpg. I'm not tuned and I've seen even better fuel economy with tunes (likely leans them out a bit).
Yes, my daily commute consists of both city driving (stop n go) and motorway driving, and I can't break 22mpg. Now if I am driving a long distance (over 150 miles or over 240km) and can hit 400 to 450 miles per tank or 27 miles per gallon.
