I've been watching mine closely, and where I should be able to go 150mi between fill-ups, I usually fill up somewhere between 90 and 110mi because "hoofing it" is something I would much rather have in the recesses of the memories of my teen years.
BTW, I am averaging 46MPG over the last four fill-ups. Is this what you guys are seeing?
