Yeah its amazing the grey colour it turns the oil. I used it with Delvax MX Multigrade 15W40 once, quite excellent combo.

There is colloidal moly M0S2 which is moly powder suspended in an oil carrier and then there is Moly DTC or Moly DibutylDTC often called, "soluble moly." The latter is the only moly form now used in modern PCMO's and gear lubricants.
Most lubricant manufacturers have abandoned colloidal moly M0S2, so you don't know what you're getting when you purchase something like Lubromoly. I suspect they are using left over supplies of powdered moly.

Are there any Moly DTC additives that don't alter the viscosity of the oil?

Not over the counter.
Remember, new organic FM's will be replacing the organo-metallic FM's and AW adds.

The general trend is to reduce or eliminate metallic compounds (but not immediately) with the obvious reduction in metallic ash and an increase in fuel efficiency.
Alleged reasons for reduction are cat poisoning and valve deposits.
There are generally two classes of organic FM and AW's:
1. Polymers including PAO, ester, and Liquid Crystal polymers
2. Ceramic and carbon nano-particles suspended in a carrier oil.
And yes, some of the above are being used as organo-metallics are being reduced.

I used this stuff a few times back in the early '90's in my Honda Civic when we lived in New Hampshire. It was my commuter car and it was never garaged so it would often sit out all night in -10 to -20 degree weather and starting the car in the early morning was brutal. You could actually hear the engine making grinding sounds for the first few seconds. The moly completely eliminated that because it apparently had coated the engine parts and provided lubrication before the oil started circulating properly.

I bought a bottle of it a long time ago and add a small amount to my oil change. Bumps up the moly nicely.

how do you now its MoDTC?
It's not the grey stuff. Plus it says so on the label.

Bumping this thread in case anyone has new information. I'm thinking Mobil 1 5w40 (CJ-4) could use a little moly and maybe a little more zinc.

Does any one know?
Not sure if you saw this thread, it is a little old but it shows a lot of VOA's redline is one of the oils that added a nice shot of moly. Check it out. HTH

An online friend is sending me some MoS2 ultra fine 1.5 UM he uses to coat bullets. As far as how much to add to the oil is the big question. My guess would be about a teaspoon or two would be all that is needed for a 5 qt sump. I'm figuring to mix it into some oil with a small electric mixer and then shaking it up.
I have an old beater I want to try it in for the sake of experimentation. I was told most of it would stay in suspension, and the small amount the settles out will be quickly mixed back into suspension as soon as the car is started up.
Has anyone else tried this? If so how are you mixing it, and how much are you adding to a 5 qt sump? I realize I can mix some up and send it in for an analysis, I'm just looking for a good start point before doing that.
Thanks

If my math is correct, 1 teaspoon of pure MoS2 in 5 quarts of oil would be a boost of 1042ppm.
4 quarts would be 1302ppm
6 quarts would be 868ppm
That's a lot of moly. If I were willing to try it, I'd do at most 1/4 teaspoon for a 5 quart sump, which would be a boost of about 260ppm.
