900 mile trip fuel mileage results

[beerformeplz]

Took a trip from Chesapeake Va. to Pensacola Fl so i figured this would be a good time to get fuel mileage info. Only mods to my truck are a Newton leveling kit. 2009 with 7000 miles.
First tank was down Hwy 58 so I averaged about 60-65mph and got a hand calculated 14.8 mpg computer was 14.6. Once I got to Hwy 95 averaging 75-80mph it went to 13.2 computer was 13.1. I was supprised how close the computer was to actuall mileage.
On the way back I tried some of fords cetane additive and I got 13.7 on the way back. So it does help. Best price on fuel was $2.79 worst was a Shell station in Ga $3.29.

my truck began to get better milage once i reached 20,000. i have 25,000 on it now. i have heard that at 40,000 miles it gets better. i was getting about 10.5 average mpg with a 50-50 mix of highway and city. once turned 20k miles, went up to 11.7 and got 16.5 mpg on freeway at 70 mph. then dpf regen kicked in at 25,000 and went back down to new but i ran into a fuel system problem and it is being replaced by ford and engine work or replacement coming. everyone needs to follow severe duty schedule and change fuel filters every 10k and only have the dealer service your truck. trust me boys, i learned first hand. I would love to get rid of my dpf filter but i live in California and they are now smoging diesel pickups from 98 and newer.

I noticed that if Im doing over 70 and my truck regens it starts to surge like it has a miss or something. Guess im waiting awhile for a dpf delete and tuner so Ford doesnt have any ammo in case something goes wrong.
