Oh I dunno. That stuff is pretty thick and tacky. I would think it would make the cold start romping worse than it already is with these engines.
Maybe some 6.0's are as picky as mine, I dunno. I tried Mobil1's(which I think is one of the best synthetics around) SUV/Turbo diesel synthetic, and thought I was gonna have to chain my truck down to keep it from rolling over 'cause it romped so hard. I stick to straight synthetic Rotella or motorcraft oil now, with no additives.

I tryed it once on my new IROC ( way back then)your suppost to drive for about 50 miles so it pregnates to the cylinder walls. While I was doing it the engine blew. Thank god Chevy put a new motor in for only 100$ dedutable. I wouldnt do it.

Do not use it. That also applies to K&N filters - they do flow better, they have larger pores that also flow more dirt than a stock paper filter. For proof, feel the grit on the inside of your clean air tube if you run one. The filter oil will also mess up the heated MAF element.
Try synthetic oil instead. Change your filters at the recommended intervals. Drain the water from the HFCM every month. These are all things that will make a difference!
Synthetic oil will help cold starts. If you don't tow, use 10W30 when it's below 90F outside.
Google it and make your own decision. [img]/ubbthreads/images/graemlins/wink.gif[/img]

I have a buddy that deals in Prolong additives. (Flame suit on) I use it in all of my vehicles. I won't go into a long-winded story, but that stuff saved the $7K engine in my '73 Torino, and it sold me. I don't use it on every oil change, just once or twice a year. This stuff is not thick like Slick 50 is, and I noticed less noisy cold starts when I used it, especially with my '02 7.3L
Please do not bother with the "snake oil" speeches. I am not an idiot, and I wouldn't use Prolong if it did not yield me results. Most folks with critisism on this product have not, nor will they ever actually try it, and I didn't, either, until I witnessed results from someone else's truck.

I have no experience using slick 50 in a diesel. Even so, wouldn't use it in mine.
FWIW..I did use in my old 88 460cid. Don't recall any early on problem, but I dumped oil not long after. Why, cause found out later it could crud up internal parts. Another product (not related) at the time "STP" turned out to be no more than a $$$ oil thickener.
T73...I used "prolong" in my old hi mi. chevy V6. It did decrease oil consumption. Will be using soon in my Buick V6. If it works same, I'll continue to use. Dont know on diesel?
In my 1983 Chevy S-10 (my first vehicle) I used to use a product called Motor Honey. I can't say as it helped anything, but I was 17 years old and thought it helped the 2.8L engine run better. That truck had 118K miles when I got it and it had nearly 200K when I sold it. I miss that truck.
FWIW, I'm not adding anything to the motor oil in this truck. IIRC, I believe the owner's manual even warns against adding stuff to the oil.

I thought these guys had been scared off years ago for misleading advertising. Bottom line: the temperatures within the engine are nowhere near what would be required to bond PTFE to anything, even if it were so inclined. With the good oil filters we run, I wouldn't be surprised if most of the powdered PTFE ended up right there on the first pass anyway. Hope so, I sure wouldn't want that stuff or the wrong-for-our-engines oil that it comes in anywhere near the injectors.
