Hi, [Not a Diesel fan here] All of these Diesels are very well built. As for Ford, the 7.3 L is a time tested tough engine. But the 6.0 L is very powerful and you can feel the difference when you drive one. [much faster than the 7.3 L] Although it has had some minor problems mostly computer related. I think they got it all ironed out; Great, now you are ready to start produceing the next Ford Diesel 6.4 L.
like I said, I'm not a diesel fan, but with Chevy, Dodge, and Ford You diesel people should be happy with your choice.
Many times, such as now, when talking about Diesels, I hear the word GASOLINE. Be very careful, one accidently, Diesel tank filled with Gasoline will not only stop your engine, but will kill it dead. Trust me, I have seen it first hand at the Ford dealer where I work. [unconfermed] Customers stated, "I loaned my truck to a friend and they put the Gasoline in it."
