There's a TSB out for the 09 Fit's MPG gauge. There's also an engine-related recall on the 09 Fit. Take the Fit to a Honda dealer, and have them do the MPG gauge TSB while they're doing the recall work. Our 09 Fit's MPG gauge was off by that much before the TSB-indicated reflash was done. It's been within 1-1.5 MPG of hand-calculated MPG ever since we had the reflash done 20k miles ago.
