I just read something on the 6.4 that is quite amazing
This may be old news to some of you guys who do a lot of research but I was over on the Official Ford Truck site reading up on the 6.4. It states, and I quote, that with the precision of the Piezo injectors the engine will start in LESS than 2 seconds at 20 BELOW zero. Huh. That sounds pretty wild. If is true that is gonna be one sweet motor. I have never, ever heard a claim like this on a diesel. It probably had a disclaimer somewhere that said it had to be plugged in to do this, but I did not see one.
Re: I just read something on the 6.4 that is quite amazing
...and the 6.0 was supposed to be quieter and get alot better mileage than the 7.3.

A proper running stock 6.0 WILL get better mileage than a stock 7.3 under the same operating parameters

Well in my case that is simply not true, sorry. I have put a lot of highway miles on the '97 F250, the '00 X (both 7.3L), and the '03 F250 (6.0L), and we drive the same way all the time, and the 6.0L has always gotten a MPG or two worse. (The other trucks would do 19, sometimes hitting 20, while the '03 gets 17-18 year in and year out.)
It also gets a couple of MPG worse around town, but I can't be positive that I'm not "using the power" there, so that's not quite as damning evidence.
The '03 has nearly 80K miles on it, so it's not a break-in thing, by the way.
I sure don't hear Ford touting that "up to 10% better mileage" line any more.
As far as being quieter, yeah, it's a tiny bit quieter. But it's a lot closer to the 7.3s now than when I bought it (when it had pilot injection.) So when Ford says "quieter and better mileage" and they so blatantly lied to me last time I heard that, I'm not buying it this time until I see the real world evidence.

[/ QUOTE ]I have to call BS on that. I have kept logs on every single mile on all of my trucks. I am actually trying to sell my 6.0L right now since I just bought another real diesel, 03 F350 4X4 DRW SC 7.3L/auto, it averages 11.5 towing and 17 empty.
Buying my 05 F350 6.0L is the biggest mistake I ever made, since the truck will not get over 12.5 mpg running empty. I can usually get that with any of my 7.3L's towing 14,000lbs, and 18-19 running empty.
I am going to wait another 1-2 years to see how the 6.4L does. Until then my 7.3L's are going to get run into the ground, rebuild, and run again.
Re: I just read something on the 6.4 that is quite amazing
I have had my 05 to two different dealerships totaling 4 time, complaining about the mileage. And everytime they say "theres nothing we can do about it". They reflashed the computer once and it did nothing. I have my attorney looking into see if I can claim the lemon law on the truck. If not and the truck doesn't sell, I am going to get a SCT from Innovative Diesel and see if Eric can work any magic with it. Since 12.5 mpg out of a diesel is just plan horrible, I could have saved my $5,000 and got a V10 and had this mileage.
