if its the fuel additive...have at it, but if its the oil additive, i would STRONGLY recommend you NOT to do it, it thinkens the oil, which is a bad idea for the 6.0 with heui injectors, it would be ok for the 6.4 because they are common rail and the fuel system is not dependent on the consistancy of the oil for proper operation. maybe you already knew this i dont know but its your truck and you can decide what you want to do im just giving my own personal insight. hope this helps man.
ETA: i forgot to mention, lucas does make a synthetic version of there oil additive which they claim is safe to use in powerstrokes (7.3 and 6.0) but they themselves dont recommend using the original oil additive in them. either way i wouldnt use either of them.
