have a good look. MS4 in a tube is sillycone grease. you only got the clear oil when it is stood for months. trust me, i worked with this for 14 years.
it went in ford cargo cab mounts. leyland sherpa anti roll bars. and some more. the good point, its heat proof. until one of our "engieers" takes an empty and sets about it with an angle grinder. no eyebrows. (we had some great "engineers")
the only thing i can find wrong is the nut on the steering wheel.
its now called dc4

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.
Happy Shooting!! Paul.

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

Forget all things Silicone now.....its gone lithium based greases...
Tony Walls St2 or ST1
Deal with silicone grease is when the silicone separates it will gall even hardened steel..
Thus ....its not so much the mix as in the case of Molys but when it separates out...
It can be something as simple as some Youngs or WD used elsewhere but gravitating causing the components of the silicone moly to separate but i have heard theories on great pressure forces causing it...in an industry completed unrelated to the gun trade.
Its such mucky smell stuff anyway ...
Another good alternative is lubriplate ....the original white grease.....fine with just a dab now that we got Delrin guides and top hats etc.
