I had a crewcab 450 2wd with the 6.4 and it was the biggest piece of junk I have ever owned.. I could not get any better than 8mpg without pulling and put a catback, cai, gutted the dpf filter and it gave me 1mpg out of it.

I could not wait to get rid of it.. I will never buy another Ford in my life again.

That 6.4 diesel is junk.

but 8 mpg??? 30000 lb fire engines get better mileage than that!

(of course those are pre-emissions engines...) I shudder to think what a new engine's mpg would be
