well, I'm starting to regret big time not jumping on a V10.

but I guess we'll see when I get this dump trailer and its fully loaded and I'm trying to tote 20k+ up hills.

Tim,
Give it some time.
Diesels take a little while to seat.
My truck slurped up the first few tanks too.

I guess the biggest thing that kills me is neither my 03 or 04 did this bad, and yet the 05 was supposed to be a better engine?

frustrating. And I'm going to make a 1300 mile run to Iowa in a week...at 11 mpg...ugh

 

[HOIB]

Tim, my 04 is doing that bad, but without the other issues.

Not trying to stir anything up, but it makes me happy that I have a antiquated 7.3l that gets 15.5 to 16.0 in the my CC 4x4 dually.

Yep, I miss my old 7.3. 15-17 mpg all day long. The 6.0 is killin me at 12 to 13 and that is going easy on the pedal BTW $2.55 per gallon today

I'm not discounting anyones mileage, or saying some of the bad mpg 6.0l are running right but...
When the advertisements for the 6.0ls came out didn't it say something like a 10% mileage increase? If so, that's only 1.5 to 1.7 mpg increase based on a 7.3L getting 15-17mpg. The way some talk, you'd think they were expecting 25mpg on a similar truck with the 6.0L.... And FWIW, if I was only getting 12mpg I'd be complaining too.
