The main killers of injectors:
Oil maintenance is huge; the 6.0 injectors have exremely tight tolerances and dirty oil destroys them. Also heavy oil the 6.0 needs the thinner oil for only one reason: the injectors.
Low fuel pressure is the next problem; not enough fuel pressure and the intensifier piston beats away at the injector shortening it's lifespan.
The nylon screen to the hpop pump can tear and shread and that material goes straight into the injectors.
Running out of fuel is devastating for the injectors.
More than anything is the oil maintenance the longer the oil is in the engine it becomes more acidic from fuel combustion and is broken down giving the injectors less lubrication, not to mention the degrading of the rubber o-rings in the engine.
There are no good reasons for going over 5,000 miles and not to use a 5W/40 viscosity ( Ford specd. 15W/40 because 5W/40 had not been made yet) that is now the prefered viscosity.
