7.3 IDI will probably run the same no matter what you do to it.7.3 PSD uses high pressure oil to run the injectors, and degraded oil will cause it to run like crap long before sludging is significant.Of course an idiot could continue to sputter along another 10000 miles before changing the oil I suppose.
What kind of reputation does the "new" engine have, the one that replaced the 6.0 after only a few years?
Or just dump Navistar and go back to International engines like they used to in the 80's. Millions of truckers can't be wrong.
