My 2005 Sebring Touring convertible 2.7 L V-6 has the built-in gauge for fuel economy and it is off about 7% on average. Always optimistic, it's best guess was 3.8% over, it's worst error was 10.7% high. That's based on calculating FE using the trip odometer and the gallons at the pump numbers.

I use it for a relative indication of instantaneous (every 3-4 seconds updated) MPG.

Wonder if there is a way to adjust it's calibration to get it closer to reality, tho it is so inconsistent that I'd still be working with very fuzzy numbers. But it is better than nothing, I'm sure.
