After a few thousand miles on it, it consistently gets 37 mpg.

How fast do you accelerate and how much idling do you do?

I'm very careful not to idle (turn it off if I'll be sitting) and always creep up to stoplights and ease into resuming speed; also never exceed limit now... All my efforts aren't helping, and I did NONE of this with my former car (40 mpg).

Bad fuel filter? What else can I try???
