My 2017 FFH Titanium has been over-reporting MPG on the trip computer since I bought it new.  I have kept a log of all fuel tanked and calculated mpg from that and the trip miles reported on the trip odo. The car consistently over-reports mpg economy by 2 to 5 mpg. I am wondering if this is typical or is there a calibration I need to make. Sorry if this topic has already been covered - please point to that, if so.

Pretty typical. My 2013 FFH after 63k miles varied from 1.2 to 4.5. My current vehicle, a 2017 Lincoln MKZ (the same hybrid power train) after 28k miles varies from 0.9 to 2.8.


I am not aware of any calibration adjustments available.

All the FFHs since 2010 have computers that report mpg about 4% high. However, the odometers are about 2% low in mileage leaving a net 2% high or about 1 mpg.

I recorded my 2015 FFH fuel consumption in a spreadsheet for the first 25,000 miles and it over reported by 2.3 MPG. After that I quit tracking the results.

Common and frustrating for me ... my current FFH and the prior '15 both reported "generously" on the MPG.  I track the differences, but my actual numbers are from the receipts.  Just keep going the way you are.
