Here is the data from my fuel usage since I picked up my 04. I

 

Um, what's up with your last two MPG entries?? 62 and 7mpg?

I'm getting around 220 miles a tank around town, which is inline with 20-21mpg. I haven't done too much highway driving from a full tank since buying the car.

This is roughly half highway miles. You can see my cumulative MPG is pretty much converging on 24 MPG.

 

I've been averaging 23/24 mpg for the last 2500 miles or so in mixed commuting and short trips.

I've been getting anywhere from 20-25mpg in mixed driving. All this in 1500 miles of driving.

 

The mileage does seem to depend heavily on the amount of driving in traffic you do. I commute every day about 15 miles usually in moderate traffic and have been averaging about 21mpg (which is still fine with me after like 14mpg with my RX-7 ). But when I took a driving trip into the countryside, I got about 27mpg (!) even with some pretty hard driving. I'm at about 2800 miles right now.
