Maintenance, Servicing and is Silicone Oil good or bad?

I think you missed my point. We all know that that the chemical formula of molybdenum disulphide is MoS2, but just because a grease manufacturer calls a product 'MS something' does not necessarily mean that it contains molybdenum disulphide or anything else for that matter.

A grease cannot be pure molybdenum disulphide, because that is a powder, so even the so-called moly grease simply contains an often surprisingly small amount of MoS2 in a grease carrier.

If I was marketing a grease containing MoS2, I might just as well name it MD, for molybdenum disulphide, as anything else. Similarly, MS in the name might simply stand for 'more suckers' or 'makes sterling'. As I said, it stands for whatever the manufacturers want it to stand for and should not be taken as a reliable indication of content.

Why do so many call their lubes MS
Even special airgun lubes like these are also called MS

possibly because the people he buys it off calls it MS.


Castrol MS3 is a lithium based NLGI number 2 consistency smooth textured grease incorporating 3% molybdenum disulphide.

I really don't know, but at least two of those to which you linked don't contain any MoS2 whatsoever, so no connection there.
