The traffic jam and stop and go will kill that mileage in a heartbeat.
Next time you find yourself driving around and there isn't any traffic at all....fill it up. Get on the freeway. Drive 65-70mph for 20 miles or so, turn around and come back to the same pump and top it off.
Total mileage / gallons utilized = see what you get. That will let you know if you have a problem or not.
