Just on the chance the Ford engineer hasn't thrown his arms up in disgust, I do have an observation with a follow up question.

You can see my truck build in my signature. A friend has the identical build as mine. My truck currently has 1,200 miles, his 2,900. We recently drove 120 miles, all interstate, in our respective trucks one behind the other (and no drafting). My mileage for the first 120 was 13.9 going north and 13.3 south (10-15mph winds out of the south). My friends truck was 16.6 north and 16.2 south. These are hand calculated hard numbers.

Is there a reasonable explaination on two identical trucks getting drastically different mpg's?

There are several factors that can affect it. Mechanical breakin state, fuel quality, the software version on the PCM, tire air pressure, etc.

120 miles is not a long enough trip to get a good average, all it would take is .5 gal difference when filling to throw the calculation way off. I always like to check over at least 1K trip get a good feel for the real mileage.

I did notice a difference in MPG as I got more miles on my truck. I drove pretty similar distance as you did and got about 14.5 both ways. I also had a tailwind from the South but I head wind go home. Seemed like 16-17 there and 13-14 against the wind. And those numbers were with the cruise set both ways at 70. Now that I am over 2000 miles the MPG seems to have steady off at around 11.5 for all city driving. Not on the highway that much, only work 4 miles from home.

In honesty - we only had Mike's time for a day, out of his generosity he came back in his own time to answer our questions when they were made at a later point in time, for which we are very grateful for.
I'll close this one out.
