Tungsten Disulfide (Wolfram Disulfide)

[MolaKule]

But are the Calcium Carbonates sticking to the metals like they say?

Yes, since it has a sulfate component to it, it has an affinity for depositing this component
onto metals.

I have no idea what Redline means by 'sticking' but the chemistry definition in this context is as follows:

The fraction of all atoms incident on a surface that are adsorbed on the surface.

Not gear oil but Ravenol's motor oils contain tungsten that they are happy to advertise as an advantage....

Liquimoly's Molygen line of motor oils also contains a tungsten-based friction modifier. They sell a MoS2 for gears product as well for manual trans, diffs, etc.

Where do you have this info from? I have looked at their datasheet and I could not figure out if that is true.

best to look for an VOA or UOA that lists tungsten. If the friction modifier isn't toxic it won't be on the safety data sheet anyway

Nothing new..

I think the liquid tungsten is an amine tungstate friction modifier similar to or the same as the di-tridecylammonium tungstate that Molakule mentioned earlier.

Because I know..hahahaha. I've done virgin/UOAs on it but had to request tungsten as an analyte/pay additional for it from BS. It's not listed on the data sheet but that is what it is.
