I too have run 10 miles when the computer said "0 miles to empmty" and still only put 15.6 gallons in it (I was gettign 16.5 mpg). I have several Fords, all of them have this computer feature. I have found the mpg is very accurate, but the "miles to empty" are conservative. Like on my F-150, it said I had 31 miles to empty; it has a 30 gallon tank and I was getting 17.5 miles to the gallon, yet I was only able to put in 26.7 gallons. I think the computer may have a default setting in hopes you fill up orior to "0 miles to empty" so you do not run out fuel.
