    My DIC is usually off by about 7/10's of a gallon per 12 gallons it says I use, in the bad direction. In the winter I'm getting about 14 city and 26 highway, summer 16 city and maybe 30 highway. My mpg dropped quite a bit when I went from stock alloy wheels to heavy 18's.

    A little off topic from the OP question, but, with everybody noticing such a loss in MPG when switching to larger wheels (as mentioned above), I think I will keep the little 16's on for a while. Stout new BFG tires will help out the looks and traction, and maintain MPG, because my Michelins are dead.

    I've got 235/55/17 '05+ Bullitts...and they are heavy wheels. You can click the link in my signature for mods...I get anywhere from 28-32 MPG's on the highway constantly...mixed city/highway I'll see about 22-24. In the city...if I'm nice to it...about 15-17...but most of the time about 12-14 in the city...because hammering on it from 40 or under is fun...and just leaves 2 nice black marks

    What link goes to your mods? Not either of the two I see. I'm sure the cam doesn't help. Aren't you on 3.29's?

    ^ Maybe you drove with one foot on the brake, or some hawt heavies in the back seat?

    But seriously, as been stated, it all depends. Were those 100 miles accumulated making 1/4 mile passes at the local dragstrip?

    ^ Oh yes, if your cat is clogged you will be getting low MPG, and lacking a lot of power. Best to get that fixed soon.

    If the converter is clogged...beating on a car would be the last thing I'd be doing.
