I drive an average round trip of about 12 miles. The first and last 2 miles are jumping on and off 50-60 mph roads. Everything else is stop and go in small city traffic. I usually get around the upper 13s and low 14s. I'm still running the stock 235/70-17 street tires with 8 inch rims which makes them squish a little bit more than usual. When I'm staying at a set speed this is what my mileage is usually like(keep in mind I live in hilly country where there is no strait or flat road):
50's=18-22
60's=16-19(I'll probably to do some data logging to find a trend to explain this)
70's=17-21
80's=17-20
