I know the local ambulance fleet has a crap load of 6.0's, no problems with them as they follow the Ford maintenance schedule religiously and they use Ford filters and fluids to boot....My buddy works for Ford, he swears up and down that if you do it "Ford's way" you will have a good experience with your 6.0....The biggest EGR failure cause they see is people using the wrong coolant and mixing it with the Ford stuff - causes a sludge to form in the cooler tubes - plugging them off and ruining the cooler.
