And more than 50% of those sales have to constantly be returned to the dealerships to fix problems. The 6.2's and 6.5's weren't the greatest diesel engines, but to compare them to the 6.0 is just plain ridiculous. At least for the most part you could count on either of those engines to run right. The 6.0 might be a somewhat adequate performer, but half the time most don't run right, and you will never be able to change public opinion or the reputation that they have. When even diehard Ford guys will tell you not to even touch an engine from there beloved brand, you know it's got major problems. Some people have had great luck with 6.0's, I have a friend that has an 03 that hasn't had one lick of problems in 115k miles, but unfortunately those kinds of good situations are few and far between. If it were't for the nightmare of the 6.0, Ford and International would probably still be business partners. That right there shows you how much pain that hunk o' junk caused either side. It made them part ways on a known successful business commodity.
