Just thought I'd share a little blurb I found when trying to decide what grease to go get.
Its mainly about Synthetic Moly grease, but it's a good explanation of grease in gen.
------------------------------------------------------------------------------
Lithium is the base material in the grease, moly is an additive in the grease, and synthetic tells about
the type of oil held in the base.
The base is the thickener. Lithium or lithium complex is probably the most popular grease base material.
The base is something like a sponge. It holds oil in its pores, and the oil does the lubricating. The oil
can be conventional or synthetic. Molybdenum disulfide is a dark gray powder that is very hard and very
slippery. It is one possible additive to grease, and moly is excellent for slow moving, heavily loaded
points...I use moly-additized grease on the sliding spline on the driveshaft.
So, grease can be lithium base, contain synthetic or conventional oil, with or without moly.
Top quality lithium base moly grease is fine everywhere. Less than top quality moly can contain abrasive
particles that can damage needle, ball, or roller bearings.
-------------------------------------------------------------------------------
So a graphite grease is prob similar to above but with graphite rather than moly.
Also read that moly and graphite based are good for non-metallic parts - ie. nylon gears.
