Hank,
Call BS on whatever you want but you won't offend me!! I have been around these trucks way to long. I know they are capable of and what they aren't, I also don't believe everything I read on the internet. The person I was speaking of above is named Dave Whitmer, he is a member of another forum I was very active on for years, and I have spoken to Dave on several occasions, the last when he was building the canopy for his truck.
Here is a link to the add in Diesel Power featuring his truck!
2000 Ford F350 Power Stroke Diesel Truck Mileage - Diesel Power Magazine
It seems Dave has now cracked 26 mpg, just barely but he is there. What the article doesn't mention is all the weight that was taken out in order to do this, I know the bench was removed and a single bucket seat was used, the headlights had aerodynamic pieces added to them, every corner that could be smoothed out was done, all seams were taped and evern the wheels had cone type pieces to go from the center cap to the outside of the wheel to cut down on the wind resistence from the lug nuts!! Read the article, he is running at 1450 rpm at 60 mph with his custom 3:08 rear end, no spare tire, IIRC he had removed more than 900lbs of weight from the truck!! the AC was removed, clutch fan etc...... This man has been working on squeezing every tenth of a gallon that he can for years now!! Do you really believe a stock truck can come within 1 mile and 7/10ths of this.
I will say I don't know the route he took or the terrain, but it was a short trip, so if he coasted downhill both ways and had a very strong tail wind maybe, but I still doubt it!!
Sorry, my opinion, and I am sticking to it!!
Read the above article and ask yourself if you still believe a stock truck can run almost 24.5 mpg!!
Have a Nice Day
NCH
