Average Fuel Economy Readout PROBLEM

[rbattelle]

After my last fill and calculating 16. 9mpg highway (AC on) with the overhead at 15. 3mpg, I did the hard reset. On the way back to the house, I saw 17. 0mpg :--)which is the highest number I have ever seen out of the overhead. The previous max was 16. 2 on the overhead with a calculated 18. 0. Now if I can just stop from losing one mpg for having the AC on, I would damn near be happy with this thing. Oo.

One option is to slow down 3-5 mph if you`re running A/C. Then they'll balance out.

the highest i've seen on the overhead is 22. 0 mpg while going along the highway [just filled up minutes before going out on the hwy] and the lowest i've seen on the display is last saturday when i had a trailer behind me. filled up and drove the thing with WOT lot of the time, and it was showing 9. 3mpg at the end, and is still showing low even though i have been trying to drive nicely. oh well, that last tank of fuel i didn't pay for

My overhead is consistently 3 mpg lower than hand calc. I did the BIG reset, and nothing changed. Is this something the dealer can fix?
