Disappointed in MPG of my 6.4L

Enorma.......Understood, but at 80! come on.......even with 3:73's your taching about 25-2600 rpm and slightly out of the rpms typical of good fuel economy.
All I'm saying is with out all the information, those numbers do not make sense, something is missing
Better mpg at 65mph vs 35mph quite possibly but doubtful at 80mph, IMO.

I called Ford's customer service line and they were going to send a tech engineer to Utah to look at my truck. I was just informed that they closed my complaint file because I have 35 in tires on my truck. No engineer will be coming. I have owned 23 Ford trucks 6 6.0, 3 7.3. All of these trucks had 35's on them with 3.73 gears and recalibrated speedo's and they consistantly got 10 w/ a trailer in or out of town and 13 - 16 w/ no trailer in and out of town.
I am extremely disappointed with Ford. Also 6.4 performance in my case is about 80% of what my 6.0's were. I have an 04 6.0 that will runcircles around my 2500 mi 08. If you are thinking of buying an 08, wait and buy a Toyota diesel, the japanese build quality and efficiency, and they care about customers who have bought 23 different trucks from them.

Good luck. Congradulations on your new truck. I'm sure you will find a dealer that can get this problem resolved for you. You can't be using fuel at that rate unless you have a leak! Can you?

It's my misunderstandings that the EPA (four EGRs and DPF) have something to do with it.

Yeah well, the mileage may not be up to what some expect ......especially since no one has enough mileage on one to consider it broken in.
EPA has their fingers in way to deep and we will all continue to reap the rewards of what appears to be lower mileage, performance and increased cost of ownership. But ya know, I'm still happy with my new truck, even with the price tag.
My previous 1999 7.3, crew, 4x4, long didn't due much better. My truck before that was a 95 with a 302 that sucked fuel....prior to that I had an 88 with a 302 and it to sucked and my 79 with a 400 was worse yet. Point is, NONE of my prior trucks is half the vehicle this one is, weigh near as much or had even close to the same capabilities.
I'll reserve judgement on the 6.4's mileage potential until such time I hear factual reports from someone with 50k+ miles on one.

All true - especially about the 302 - they should have never put that thing in a truck in the first place (my 86 f150 has one). I am curious to find out what sort of change there would be in fuel economy as these trucks age. But I remember a similar thead a while back about the 6.0L. 19 mpg was what some owners were claiming 500 miles from the show room floor. But that was likely a lighter truck and it had less of the emission controls that the 6.4L has been burdened with. I guess time will tell.

My 08 is a crew cab short with 3.73ls. My frustration is simply that this truck doesn't perform or get the mpg that any of my 6.0's had. I replace my truck every year at 25-30K miles because I use it for work and as the family hauler. I have never had good luck with Fords out of warranty and I do enjoy the tax benefits of trading yearly. My trucks are immaculate when I trade them and I don't beat them.(unless you think towing a 7000 pound trailer at 80 is abuse.)
The trailers I tow both weigh 7K loaded, both are enclosed Wells Cargo tandem axles. One is a v nose 27' , the other is a square front(w/nose cone).
I'm not embellishing the numbers. I spent $730 plus driving from northern utah to las vegas last week. When my 04 had 40 miles on it I pulled this trailer to Seattle and got a consistant 10 mpg driving 79.9 miles per hour.LOL

I should also add that I've never seen my mpg increase after so many miles. My 04 Excursion has 46K on it and it has the same size lift and tires as my 08. By the way the 04 got 16.8 the other day on a trip averaging 65 mph. It also has 3.73LS. Turning over trucks at 30K mi prevents me from "breaking in" the diesel. I'm glad to see a dodge man be honest about mpg on a cummins. All my dodge friends swear they get 20 mpg to infinity on theirs. BS. My 03 5.4 Expedition gets 8 mpg and won't go any faster than 70 pulling the 27'. (The square front is an 18')
My yearly bill in depreciation and fuel has been 10-13K. Thanks to my 08 it will be 21K plus. This thing should fly to the moon for that kind of money. Maybe I'm just bitter.

But back to your question. I love the way it pulls. Even with a 18k lb trailer it pushes you back in the seat when you hit it.
