 I own a 2008 F250 turbo diesel Ford. It is the worst truck that Ford has ever made. I am on my third motor, with only 30,000 miles. That's right 30k miles. absolute garbage motor. The 1st motor blew up at 15 K. the 2nd went at 20 K .The 3rd at 29K. I obviously don't drive this truck hard or a lot; so there is no reason for motor failures. It has so many repair items documented by Carfax that I can't sell it without a huge loss of money. Stay away from the 6.4 turbo diesel. Ford mechanics admit that it is junk(off the record of course) I finally sold it and took a 10k loss.  Good riddance
