SuperC - looks like you've got initial break-in well underway, based on that recent segment. Good job...and yes, you will continue to see improvement as time / miles go by.
Your city / highway mirrors mine - about 33-35 on my daily commuter loops, and 42-44 on my rare forays on the interstate. BTW - I don't reset the trip / instantaneous mid-trip (it's reset when I start the car cold), and anything less than a full tank (or nearly so), I report as a 'segment'
Ericbecky - isn't it the truth ? Breaking 40 with the car, as you've done along with all of us, is a special feeling. Either Xcel or myself will be making an 'attempt' in the next few weeks, and I'm expecting 55+ for the tank, as a 'max attainable' (40+ seems to be easily achievable on the highway w/o pushing to extremes, as the posters in this thread attest to).
Tink - Indeed, I've come to that realization myself over the last few weeks. Most of the time, I run out of road before the indicator stops climbing; or, in other words, I haven't seen the best out of my car yet. That's how Xcel, Hot Georgia, some of the others do so well - their commutes are *so* long, that any minor snafus are absorbed more easily into their averages. When you have a shorter trip, any problems encountered during the drive affect the average that much more. That's why my tank avg is what it is, as well.
gonavy - outstanding mileage on a 33mi commute, given DC-ME-VA corridor traffic! If I might be so humble to suggest that you 'count' the cold mileage as well - it had to be traveled, so it's part of that commute segment. Otherwise, you wouldn't have such a delta between your segment and tank averages
