I use this stuff (Sta-Lube Moly-graph) for general lube on my cars, but buy
the
CV-joint grease for CV use.  Sta-Lube makes a "CV Joint Grease" (Product
No. 3174)
specifically for CV joints (although the MOLY-GRAPH tube says it is
suitable for
CVs).  I have used both this and Lobro grease, but the Sta-Lube, as you
say, is
more commonly available in my Friendly Local Auto Parts Store.  The
Sta-Lube CV
grease says all old grease must be removed and the joint solvent cleaned
before
the new grease is applied.  I don't know if this means that the grease is
somehow incompatible with other greases.  This might matter to folks who use a
needle to inject new grease through their boots.

Both Sta-Lube Moly-Graph and their CV joint grease contain molybdenum
disulphide.
The Moly-Graph also contains graphite.  The CV joint stuff says it is 3%
Moly-D,
but I don't know the percentage in the other -- it does not say on the tube
I've
got.
