    My GF drives a TC and it gets about 30 MPG mixed city/hwy. Anything bad would have a CEL but definitely make sure fuel system is good to go (fuel filter/injectors), and could also make sure the air pressure in the tires are a good 35-40 psi.

    "ecu pushing out too much fuel"?
    Well yea, if it's rich you'll notice poor mpgs but that's not the cause.
    It doesn't just do that, there has to be a reason for it to be rich. ie the vacuum leak barefoot suggested.

    It should be under a factory warranty no matter who owns it now. I would take it in, they might have a re-flash for it. Possibly better fuel mileage and better performance.

    I'd say o2 sensors would cause that much of a noticeable fuel lose. Unless there is something wrong with the fuel system.

    You need to get actual miles to the tank information for us to understand how severe of a situation it is. My girl's Altima gets worse gas mileage than my old Impala and her car is in great working order, it's just that she drives ITP and is pretty aggressive, so a 2.4L gets about 21mpg. Also, are these numbers achieved around the time when we were getting ice and snow, my mpg's dropped by about four because of the slow safe driving and defrosting of windows and stuff.
