I have been researching molybdenum disulfide (MoS2) for a while now. The research I have read is very compelling...up to the point where I am going to try using this product in my 1999 SS.

Of particular interest are the engine oil modifier (http://www.mrmoly.com/engine-aide.html) and the gear and/or transmission oil/fluid modifier (http://www.mrmoly.com/gear-aide.html or http://www.mrmoly.com/trans-aide.html), depending on if you have an Auburn or Torsen differential. This might be the answer (or at least help) with all of the gear whining problems that plague the LS1 community, especially us with 4.10's.

Anyone else have any comments? I find this product to be pretty fascinating.

Moly is an excellent antiwear additive for oil, but you are playing chemist if you add it to another oil. You are better off just buying an oil that uses moly in it's blend already, such as Redline or Schaeffer oil. Mobil 1's new formula even has a bit of moly in it too and so does Royal Purple. More and more oils are starting to add moly all the time, because with GF4 regulations calling for lower phosphorus levels, they need to add other antiwear additives to make up for it. In dino oils, Castrol GTX and Pennzoil both add a tiny bit of moly too.

If you just add moly to a different oil that doesn't have it, you could upset the balance of the oil and it will oxidize faster and it's Total Base Number will drop too fast as the oil will work itself too hard.

If for some reason you do decide to add this additive, run half as much as they recommend. I looked into this stuff before and it's very highly concentrated moly. You don't need as much as they give you. In smaller doses it will still have the desired protection, without upsetting the oil's balance as much.

Thanks for the reply Patman. BTW, I am a chemist! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Seriously though, if you are going to use this product, oil analysis is the best way to determine if it's use is safe or not, and determine the correct dosage too. I will say that this additive is going to be a lot safer than those snake oils out there, that is for sure. Let us know the results!

I am getting ready to do back-to-back before and after oil analysis with Dyson Analysis (Terry). I will keep all informed of the results. I use a full 6L of Mobile 1 when (and a Mobile 1 filter, M1-206) when I change my oil. I am looking to run about 6-8% by total volume. I will add the moly in batches of 1-2%. I'll be sure to post complete results as they are obtained as well as my subjective opinion and impressions of the additive.

I'm curious though. Did Terry not recommend Schaeffers oil to you? He knows you want moly, and I know he's impressed with how Schaeffers blend oils perform, which is one of the reasons I started using it. I too was considering adding a moly additive (our CDN version up here is called Molyslip, but it's the same company as Mr.Moly) but ended up deciding on the Schaeffers since it seems to use just the right mixture of moly.

I only e-mailed Terry to let him know I was interested in using his oil analysis services. We didn't talk anything beyond that. There seems no reason why I can't just add the Moly after choosing the oil I want (Mobile 1). Besides, the moly comes in a colloidal solution suspended in oil. Exactly as if it DID come already in the oil I were to choose. This way I get to pick the percentage composition. Like I said before, somewhere in the 6-8% region is where I am going to be.

Supposedly Mobile 1 uses about 90-100ppm MoS2 (as of the recent formula change), a couple other oils, like Valvoline, use 20-40ppm MoS2. Redline, from what I have heard, uses 500-600ppm MoS2.

I looked into MolySlip too (on the web) and was unable to find anyway to order it online or otherwise. Their site suggested that CarQuest distributed it nation-wide in the USA but I was unable to find it on the shelves at a local store. They told me they had never heard of the product and knew nothing about it. So I searched the web somemore until I found Mr. Moly. That company had an online ordering system and I could find absolutely no difference in their composition (as described).

Actually Valvoline doesn't use moly anymore. Only their Maxlife had it anyways. A virgin analysis on their early Maxlife formula showed 290ppm of moly, which is why I started using it. After my first analysis came back showing only 1ppm of moly in my sample, I was pissed!! I then found out that they stopped using it. Other recent analysis results on various Valvoline oils show they don't have moly either.

I'm not quite sure why Redline uses so much moly though. Only a portion of that moly they use is going to bond, the rest will just remain in the oil. So they might be spending needless amounts of money on their oil (since moly is expensive)
