Similar, same 'active ingredient' (Molybdenum Disulphide. [MoS2]), different
MoS2 is awesome stuff when it comes to lubricating metals. It's got a very
two-dimensional molecular structure like graphite so is very slippery but
unlike graphite it has an affinity for metals and can bond to the surfaces
on a microscopic level. This results in a semi-permanant lubricated layer on
When I used to work in an automotive engineering shop we used it on 'oil
film' bearing surfaces during assembly so they'd be protected and lubricated
on initial start-up until the oil had time to get around the engine (hence
the 'assembly compound'). It was particularly important with racing engines
as they were usually very expensive builds so no chances were taken. (The
place where I worked specialised in high-powered racing jet-boat engines and
also worked on quite a few speedway engines.)
MoS2 based greases are also used for open gears and rollers in industries
like mining. I have a tube of MolyBond GA 50 (50% MoS2 by volume) here that
I used when I swapped camshafts in my last car as well as when I stripped
and tuned my air rifle. It wasn't strictly needed for the camshaft job but I
had it on hand so why not? It's most useful when assembling ICEs that might
not be fired up straight away. It doesn't drain away like oil does so stays
where you put it until it's needed.
MoS2 isn't the cheapest lubricant at several hundred to a thousand dollars a
kilo (depending on grade). That's why most 'moly grease' that you might buy
at your local auto-parts store only contains 5% MoS2 (and isn't much better
than a good non-MoS2 grease). The 100g tube of MolyBond GA 50 that I'm using
cost me $70 (In the automotive engineering workshop we used to have 5kg tubs
of the stuff at each assembly bench - I wondered why the boss was always
saying "you only need a little bit!" and we didn't use it on every job.)
However when you need it there's nothing better.
It's the primary ingredient in any number of oil additives, some of which
claim that you can drain the engine oil after adding it and running a while
and the engine would continue to run for a long time.
