Not to keep dragging this out forever, but, used to be, the greases came in
petroleum-based and synthetic-based.  For obvious reasons, the synthetics
are better - if there is a choice, select them.  Also, in the first years of
the "grit bearing" greases, which were designed to act as Gerald and Gary
have discussed, they were loaded with finely ground glass (!).  Yes, that's
right.  I still have a bottle of the original Fargolene with glass in it.
When I ran comparison tests in the lab, the grit bearing grease did not
perform as well as the straight grease on freshly brushed and clamped wire,
but that was prior to the newer developments where zinc is used.  That also
did not take into account how it performed over the long haul, which I no
longer remember.  Too many years ago!

Hmmm....I did not know about zinc particles in that particular product.  Nor

did I know that you could form "crystals" of zinc.  Perhaps you are just 
referring to small pieces of zinc.

But - are not zinc and aluminum far enough apart in the periodic table to 
react with each other ?   My chemistry is extremely old and consequently 
vauge, but I thought you could even make a battery of those metals (with 
some other components added of course).

It seems surprising to me to hear this, in any case, and its the first time 
I ever did.  Interesting.
