Ok so i have a 05 f250 6.0l im thinking of getting rid of it and buying a 08 king ranch 6.4l with 143000 miles as far as i know its all stock but some of these dealers dont know what theyre talkn about the truck is kinda far away and i dont know alot about the 6.4 they are askn $25000 so im tryn to decide if its worth my time going there if thats a crappy price. How many miles do the 6.4l usually get b4 problems start i know thats a double edged swird type of question but just some guestimates would sufice.

 

Usually the longer they're left stock the worse. They get some serious fuel dilution with the DPF in place. Without knowing more about the truck, the price seems a little steep for the miles....
