FYI, I just received my car back after the second recall + oil change and my first two tanks have been 35mpg by true mile/gal calc (no JbD, but some spirited driving, avg speed: 36mph). Second was 32mpg with JBD (and heavier foot, avg speed: 32mph). My OBC seems to be further off though,but it will probably adjust over time.
Is it possible that some service centers may be screwing up the programming?
