I just came back from driving trip NY-Fla Keys and back. Would you believe me if I tell you I was averaging 50 MPG driving in the Keys? I did, without any dangerous nonsense like drafting or "feathering" the pedal. Due to traffic and cops I couldn't go much faster than 50-60 miles per hour, weather was perfect, so no AC with 3 people and full trunk. On the same trip, in cold weather and high highway speeds (80+) I had difficulty to get above 35 mpg. Cold weather, short trips (less than 10 miles), above speed limit cruising, racing from light to light will kill your mpg. Steady speed, 40-60 miles per hour, longer trips, warm weather will do wonders to your mpg. I know there are very few cars sold in US right now, that can give me similar mileage I get on my TCH and probably none of them is as big as TCH and that's good enough for me, everything else I don't care. If I'm in a hurry, I have no problem flooring the gas and get 30 mpg (I never ever got tank lower than 30 mpg), if I'm relaxed and cruising along with traffic I usually get great MPG, especially when I don't watch it at all . As the weather gets colder your MPG will drop even more , in the spring and summer it will go much higher, it's just the way it is and you can't do much about it. BTW, the computer in TCH is pretty accurate and it should be within 1 mpg (usually high by about 0.5 mpg) so if it tells you you're burning a lot of gas, you are.
