Not that I'm complaining but it was pointed out in another thread that the max mileage for 300Es is about 25mpg (consensus determined). I have hit 30 mpg before, and consistently get between 25-30 mpg highway. I don't normally keep a log (I mainly just do it for S&Gs), but I did do a post a little while ago with results from a trip. The two that I logged on my last trip between Philadelphia and Hartford were (note: distances are all GPS tracked, not odometer):

29 mpg:

209 miles total trip
61mph average, 86.5 max
7.2 gal to fill up (and overflow)

Coming back down, 27.5 mpg:
225 miles total
48mph average, 78.1 max (hit traffic pretty bad in CT and NY...)
8.1 gal to fill up (w/overflow)

I do know that my fuel pumps are pretty well worn and due for replacement. WOuld this contribute to increased mileage if they don't pump as much? I'd imagine the engine would run like crap and be leaned out--but I don't know enough about CIS to know if it would compensate and just have less throttle.
