whokilledthe jams: pump up your tires. 29psi is too low. It hurts more than 10%. Try 40psi if you don't want to go to max. 44psi. By the way, can you show me the picture of how you block the grille? Duct tape is only for temporary use.

I run at 42psi. You misread what I wrote before, or I wasn't clear. Either way, my point was that lots of people claim to regularly see 40mpg in unmodified xBs, though when asked how they do it, they claim they aren't doing anything, that's just how they drive-- while shifting at 3k with 29psi in their tires.
I made a post about my grille blocking adventure:

I gained ~1.5mpg or so from it. Not a bad return from about two hours of tinkering, and about $8 worth of fasteners. In a week or two, I'll see how it affected my in-town driving.
I still need a Scangauge.
