I have heard of some getting 12 and maybe a few tenths more then 12, but 12 seems to be it's high point for a stock 6.4. I don't know what they are getting for those that have removed the dpf and all the other epa "stuff".
There are people who are getting better mileage out of them. Some people are getting 15-18 MPG. There are two problems with them that lead to low MPG, and both are operator driven.
1) Trans choice. Pure and simple, the sticks are averaging 2+ MPG better under all uses. Like them or not, the autos suck 10 to 15% more fuel. The odd thing is that with everybody whining about mileage, few are willing to shift their own gears. (I guess I am the odd man out here.)
2) Driving style. The new motor has LOTS of get up and go off the line. People are driving them like a light weight performance gas truck. Hate to break it to them but their trucks weigh between 7,000 and 9,300 LBS. Accelerate like they did with a 7.3 and mileage jumps.
If you don't believe me on this stuff, spend some time digging around the 6.4 forums. The information is there, it is just buried under a ton on people wanting to blame everyone from Ford to the EPA for their choices and driving habits. The new American dream, no personal responsibility....

There are alot more problems then then the two that you mentioned that can't be helped by how the driver acts.

I agree with you there!
Here are my top 3...(in no particular order)
1. REGEN
2. REGEN
3. REGEN
If it were not for the REGEN cycle (which happens way to often), the 6.4L PSD would be up 3-5mpg easy. FORD has recognized the low mpg's...and is now offering in the Build #3 SD's the 3.55 gear ratio and massive front lower air dam. Those are facts...and the owner has nothing to do with that. Plan and simple...IMHO.
Cummings makes a Q.S.B. 6.7 L that is adjusted for military applications coupled with an Allison tranny. Its rated at 276 HP and 627 FT LB. The number just caught my eye. I'm probably adding fuel to a fire that will still probably just quietly die. I now wonder if Ford and Cummings are mating up.

You mean Cummins?

Thank you for highlighting my typo. You are correct sir; I most certainly did mean Cummins. Forgive me for my error and I will forgive you for writing a fragment and not an actual sentence. I’m sure you were thoroughly confused and could not extract the meaning of my post. Again, please forgive me.
Its just a coincidense that the B-series Cummins is now 6.7 liters and Fords future V8 diesel is 6.7 liters.

I have one of the last model 7.3 diesels in my 03. I could care less if the new 6.7 makes alot more power. If it can last as long, and get the fuel economy that the tried tested and true 7.3's can manage, Im sold!
I personally know guys with the 6.uhoh diesels in their superduties, and I can honestly say I dont think I would ever get one.
Lets hope ford doesnt have another 6.uhoh disaster!

It wasn't a total disaster, I'm not disappointed one bit with my 6.0. Y'all 7.3 guys are stuck in the past, but I guess if your happy then so be it, I just refuse to settle.

Of course we're stuck in the past. We enjoy it here. Sheldon does make some valid points though. Each newer generation motor comes with more power, more emissions stuff, and worse mileage. Not to mention they're getting crammed in the engine bay pretty tight now.
The guys that want more power can get a tuner. I'd like to see less power and more MPG's, and I'd prefer an engine that does not require the cab to be removed to perform repairs.
A word of warning about your truck Tex. The 6.0's taste better than the 7.3's. I've had 2 06's & 1 07 taken down by squirrels getting into wiring. Never had that problem with any of the 7.3's.

Is that really fair your last post there? The 6.0 and 7.3 both use the same style injection system, they could both be as easily taken down by electrical problems

It's not electrical problems. It's the friggin squirrels that walk right by the 7.3 and decide to munch on the 6.0's. I had to install a couple of cats (the 4 legged kind) in the yard to keep the 6.0's running. It's been almost a year so far and it seems to be working.

I guess it depends on what you think im stuck in the past about.
Im settling with a good solid reliable truck that will probably (not for surely) last a long time after im done with it, with little to no problems.
Theres no denying that the 6 liter has a bad rep, and for good reason. Ive said it a billion times, id love the extra power of a 6 liter, but with all the well documented problems, Id rather settle for a truck that has alot less chance of leaving me on the side of the road.
I shouldnt say it was a total disaster either, but it was pretty bad. I remember when I was truck searching, just about every ford dealer i went to advised me to stay away from the 6 liter. That was the salesman telling me that! The one guy even told me the one truck he sold almost came back to kill him, by the owner saying he was gonna drive it through the window of the dealership if they didnt fix everything!
Im just curious, would you rather have more hp/torque, or a truck that can last over 500,000 miles? I would love both, but I would take the latter of the two if I had to choose.
IMO ford motor company should have a rock solid reliable truck that will last along time. Longevity being the key in my opinion. So with the modern technology, and chance of less reliability, Im pretty confident where I settled
All in all I hope the 6.7 does well, i still just hope they dont have an abundance or problems, like the 6 liter is well known for.
