According to the other poll that I did, it appears that those that don't miss get better mpg. It also appears that the later built trucks are getting the 21 mpg hwy right from the start - without having to wait for the 3000-5000 magical break in. I wonder if enough complained that Ford reprogrammed the newer trucks to not have this break in period, maybe this poll will give us the answer

Build date Feb 2 2011. 3.73. Only misses when cold starting. When warmed up it purrs at 500 rpm. At 70 mph yesterday was getting 20.7 on hwy over a <20 mile run.

Info about my truck in sig.

Built 5/19/2011. Does NOT get 21mpg at 70mph. If I'm REAL careful I can hit 19.x mpg at 65, but that's about the upper limit. I've seen 21mpg before but only when I'm dropping in elevation over some period of time (even a very gradual, if not imperceptible drop in elevation, can get me 21mpg).

thanks, thats how mine is

I'm not getting 21 mile per gallon with 3.55, 4x4, Screw, long-bed, built-in-May, under-3,000-miles truck at 70 mph.

On the other hand, I think the tonneau cover is making for worse mpg.

At 1400 miles and getting about 18 mpgs with mixed driving, probably slightly skewed to backroads more then highway and using remote start a lot to cool it down for my wife and little one.

I think some need to get on the highway and bring it up to speed...then reset and travel 25 miles or so w/ cruise control. That would be a more accurate way to compare truck vs truck build date IMO

truckerdude

that would just inflate the numbers and wouldnt be accurate.

The way to do it is set it before you leave the house, that way the warm up, and city driving to highway is included. Most that have posted their 21 mpg runs had went for over 100 miles anyway so the few miles of sorry mpg was basically averaged out.

The ones that tick me off, get on the highway, then reset it while coasting. It starts out 30-35+ or higher and then they drive a few miles and end up with 28 and brag about their great mileage.

The only ones I trust have taken pixs and posted them of there trip computer and like i said these were longer highway trips

other problems are is the ground flat or got hills? a 2-3% incline is enough to drop the mpg by 3mpg during each hill climb. so if you got lots of hills, your average is way down and since most run cruise and the cruise will not let it coast, you don't gain anything going down the hill cause the stupid trucks are programmed to downshift to slow us down.

also wind. do you have it or not. a 15 mph wind makes a 1.5 to 2 mpg difference.

Nope...it would serve us better to get the actual MPG in similiar conditions (get up to speed and then reset and drive 20 miles). In fact, the actual numbers would not be as important as the spread of the numbers by build date.

This removes many variables...

truckerdude

no it doesn't. As you might hit the reset while coasting and start out with 35mpg and somebody else might actually be cruising along on level ground and do the reset, while another might be going up a slight incline and start out lower than the rest. The only way to check a bunch of trucks is for all to run the same highway, the same day, same time and reset at the same spot. That's not going to happen, so the best way is to see LONG hwy trips mpg posted- this gives us a good average not some bozo trying to impress me by resetting while coasting and then taking a pix 20 seconds later when it shows 30mpg
