I just got around 60mpg out of my first tank. I've yet to check the tire pressure and the car still has factory oil in it. The single biggest thing that you can do to raise mileage is drive different, IMO. I believe the reason I'm doing so good is that my HCH is the 3rd car I've owned with a "game gauge". I've had lots of practice. A non rush hour second shift job helps a lot as well. My numbers are real, have posted a picture of the dash gauges in the file area for non believers.
