None of the CRXes had lean-burn engines.

Sounds like you're getting good suggestions so far. I would guess that the tires, the ELD, and the exhaust would each cost you a little bit. It might be enough to add up to what you're seeing, but I'm not sure.

Also note that colder weather will hurt your fuel economy--the colder, the worse it hurts.
