Trajan's question was 'So what does it do again that current PCMOs can't?' The answer is above.

MoS2 in Mobil-1 (or in most any motor oil) will result in less engine wear, reduced oil and fuel consumption, reduced parasitic engine heat, reduce or prevent blow-by, longer engine life, safeguards against break-downs and repairs. It's not oil brand dependent.

BTW, how do you know the N54 was properly modded? How do you know the N54 has no problems?

MoDTC is already a component in the PI package in most PCMOs these days.

So which one is it?

You didn't actually read those pages about MoS2 that our host has provided Trajan.


Which one is it? What does it do that current PCMOs can't?

personal testimonials are meaningless. Especially when those who rely on them only accept ones that favor what ever product they use.

If you are going to repeat my words then at least get it right.
"i just think" is my opinion.

They do use it in one semi and not in any of their full synthetics. In their full synthetics they use a different moly called molygen not MoS2. Whats up with that?

Don't misunderstand me i am not calling it snake oil because it definitely isn't.
I just think its an old school additive that worked well with the oils of yesteryear and has no place in a fully formulated modern oil especially a full synthetic.

MoS2. No one has suggested a consumer source for MoDTC or MoDTP. The title of the thread contains the phrase "MoS2"

Which one is it? You who insisted that because Molykote was GM approved that MoS2 is.

Please come back when you know the difference between "a plausible-sounding argument" and "evidence."

50% is really over the top. Compared to what? Used 3in1 sewing machine oil??
If what you posted were even remotely accurate with a modern spec oil the manufacturers would be knocking themselves out cold to include it in their spec.

Thats too far fetched for any reasonable person to believe.

The key is in the words. "Up to" two of the biggest words in advertising......Still the product did work in my mower.

OT-Oh and it helped reduce fouling in my F Class rifle barrel. I could shoot longer strings w/o cleaning. Then "I" switched over to Danzac which "I" thought was better suited for bullet coating.
 
Trajan seems to hate when users of a product talk about their experiences and expects scientific evidence (except perhaps if he believes in a product). I don't know what we would have in the Oil Additives Section if people were not allowed to talk about their experiences with various products. If scientific evidence was expected for every product I suppose there would be very little in the way of posts in the Oil Additives Section.

I think demarpaint is a very good poster here at bobistheoilguy.com and I trust him. So I think we can take his word for what took place with his lawnmower. And Trav, a professional mechanic, said that this LM moly product could be very useful in earlier vehicles. Well, a lawnmower in a sense is like those earlier vehicles. It does not have all of the complexity of a modern day car engine.

In fact, I can remember when a product called Auto-RX was tested in a lawnmower engine. Or if it was not a lawnmower engine it was some kind of small engine.

Well, demarpaint tried this product in his lawnmower. He did not have much to lose. The lawnmower was not in great shape anyway.

Other guys here have also talked about using this product. I don't think I would use it in my car engine necessarily but I might give it a try in my old wheeled weed trimmer engine.
 
Mos2 would do good if you added it to some API SA oil. Mixing it with a current spec PCMO at best is a waste of money. The worst it will do is degrade the PCMO.

People and the need to mark their engine never ceases to amaze me.

If you substantiate this claim I would be surprised.

Maybe. But oil with MoS2 is more slippery than oil without. Sliding surfaces will slide more easily with MoS2 than without. If you have any doubts about that, simply dump some MoS2 into your motorcycle's wet clutch or your limited-slip differential. You will then have a motorcycle with an automatic transmission (stuck in neutral) or an unlimited slip differential.

It follows that the MoS2 lubricated parts should wear less. Even if it was only 5%, that would be nice. I'd settle for 1% or 2%. And since MoS2 stays in bearings after the oil drains out and therefore provides lubrication upon start-up, that "up to 50%" may not be that far off the mark. How much wear occurs at start-up? Suppose you could reduce just the start-up wear by 50%. How much would that reduce the overall wear?

BTW, the "claims" above were a mish-mash of Liqui-Moly MoS2 Anti Friction claims and Dow-Corning spec sheet stuff. Most of this information is in BITOG 'white papers' - links are up above.

MoS2 is an interesting lubricant. In industry, it is the undisputed king. In the consumer world... "this stuff turns my oil black".

I took the information from Liqui-Moly's website and from Dow-Corning. The characteristics of MoS2 are rather widely known. Look through the BITOG "white papers" on MoS2.

Or, if you prefer something less wordy but a bit more graphic, put some MoS2 in your limited slip differential or your motorcycle's wet clutch.

There wouldn't be much posting anywhere on the site, with the exception of the General and Off Topic section, Items For Sale, Humor and a few others. What would have to fight over? LOL

You have failed to account for the friction modifiers already present in a current formulated PCMO. The MoS2 studies are not studied with an finished lubricant.

Put some "current formulated PCMO" in your wet-clutch motorcycle. How does it work? Than, add some MoS2.

How could you possibly know how Liqui-Moly studied their product? Or Dow-Corning? Did they share that with you? Did you consult for them?

Ummm, the N54 engine is not a motorcycle engine.

You're kidding. The N54 doesn't have a wet clutch, either. BTW, does your BMW have a turbocharger?
