Note mileage at fill up. Note gallons needed for next full up, and mileage. Divide that mileage difference by gallons needed on 2nd fill up. Compare that number to cars displays. A Guy

One is reset from the reset to zero and the other is an average over time....keeps on counting as you go....As "A" says manual calculation is best....the trip computer is usually a touch generous...
