Be able to calibrate the fuel used.

On the information screen the fuel used on the screen is always 1-1.5 gallons to low so the mileage is never able to be calibrated.
If you were able to tell the computer how much fuel was really used when you fill-up the tank the miles to empty and average miles to the gallon would be much more accurate.

It would be nice to have a menu option to be able to adjust gallons used calculation in +- .1 or even .25 gallon increments to bring computer MPG calculations in line with manual calculations.
