automatic gas milage computer
I have a 2003 F250 5.4 Crew that has one of the automatic gas milage computer things on the overhead console that also tells you outside temp and heading. It has been reading 12 mpg from almoust the day I got it. Didnt matter if I was running empty or pulling a 5th wheel. Well this past weekend when I was leaving the campground I noticed it said 7mpg. Pulled over inspected everything and found nothing wrong. Pulled it home and it would adjust the reading every few min. and averaged 9mpg. It will adjust now for when i speed up and slow down. It never has fluctuated like this before. Now running empty around town it reads 13mpg. Never had mpg this good when empty but never had it read 7mpg either. It adjust fast, you can watch the milage decrease as you accelerate. Any ideas? Is something broke? Did it just decide to start working?
my 2002 does this... it adjust regularly as i speed up or slow down

It sounds like it was reset. The computer calculates the mileage since the last time you reset it, so once you have some miles on it it won't change very fast at all. If it's only been 10 miles since a reset a change in mileage will show up quickly.
You can reset it by pressing both buttons at the same time. You have to hold them for 2-3 seconds.

the overhead readout on my 2003 ranged from 7 to 27 mpg,, could never rely on it no matter how many times the unit was reset so I just left it on the compass,,
the new 2005 F350 KR has been holding within a few tenths of actual fuel calculations after the first 3,000 miles so perhaps Ford finally got it right,,
enjoy,,
