It took about 3000 miles before I started to see #'s over 30MPG. After I got north of 5000, the mileage improved to the mid 30's. Obviously how one drives greatly factors in. Took a road trip to NY in our Odyessy this summer. When I drove I was averaging 26-27 MPG. When my wife drove, that average per tank dropped to 24. Go figure.
