I think 34 mpg is way too low, my worst tank ever (I own TCH for 1.5 years and drove 41k so far ) was 30 mpg and that particular tank included driving in a snow storm traffic at 5 miles per hour for few hours, following driving on ice and very cold weather. I usually average 36-38mpg in winter and 39-41 mpg summer, much closer to the old EPA rating and I do not use any hypermiling tricks, if anything just the opposite. I think the new EPA rating had some political pressures behind as well and I totally disregard it as not representing my own real life experience, of course YDMV. BTW I totally envy Florida drivers, on my most recent trip to Fla I was averaging 50 mpg driving in the Keys, totally blew me away, I didn't even think the car was capable of such high mileage in normal driving, the best I could get around NY area was 45 mpg and usually that never lasted too long. But in the Keys with steady traffic, keeping you honest close to 45-50 miles per hour speed limit and perfect weather the car was very efficient. Now I can see how some drivers can get really high MPG numbers.
