MPG looked good on computer.....

now I need to check it by odometer and pump readings.

Had to make a quick run to Fredericksburg to pick up an ATV. As I hit the interstate in Dallas I reset the mpg indicator on the info center.

After 170 miles and something over 2 1/2 hours at near steady 70 mph and only one quick rest area stop, no load, three men, and 10-15 mph tail wind, the computer showed 22.7 mpg.
Turned off on state highways, mostly rural, but thru several small towns and traffic lights, and 100 miles later it was 21.6 mpg.

On the way back I had the fairly large ATV in the bed and no wind at all and the same 70 mph. Reset the computer when I hit the interstate and nearing Dallas it was reading 21.9. But then I got the ol' CLEANING EXHAUST FILTER message. Within the next 12-15 miles it dropped to 21.0. But then it climbed back to 21.7 by the time I ran out of interstate. I think the quick rise was due to speed dropping to more of a 60-65 mph range nearing the city.

Those numbers looked great. Now I just need to do some pump and odometer calculations to see how accurate the computer is. My previous truck, also Ford, the computer was consistently 0.4-0.5 mpg higher than pump/odometer calculations. Pretty close. Has anyone with a newer Ford compared the computer to pump/odometer calculations?
