Hot Shot Secret Stiction Eliminator is what your talking about. This company was approached by Navistar when Ford was using the 6.0 PSD and was having issues w/ injectors going south. Come to find out, the inj were fine, they just got plugged up by baked on oil due to the hi pressure oil system used to fire them and all. Add the HSS to oil at oil change and run it. Will see lots of white smoke at 1st, then nothing. The product cleans out the turbo as well. Money back guarantee. I used it in my '03 F250 6.0 for 80,000 miles and I swear it saved me $$$ for I didn't lose an inj due to it being "plugged" up.
