The other thing that could be causing the drop is that some of us new members just don't drive long commutes to work. I just bought mine last night and haven't had any time to "learn" it yet - but my commute is under 3 miles - I am going to be bringing down the averages I suspect. The engine won't even get warm before I get to work most days. Hopefully the weekend highway trips will keep my mileage above 40!
