Possibly CAT (as in Caterpillar) Calcium Sulfonate 5% Moly greases.
There are various versions, including synthetic oil bases, depending on $ and environment.
Arctic Platinum is a synthetic oil, 5% moly NLGI 0 grease for use from -50*C up to 20*C

Desert Gold is a synthetic oil, 5% moly NLGI 2 for extremely high temps from -20*C up to 60*C

Ultra 5Moly grease is available in NLGI 1 and 2 for temps up to 40* and 50* respectively
Advanced 3Moly grease is a 3% moy grease for medium load applications.
I don't know who blend these for CAT.
I've always used Castrol LMM (NLGI 2, Li complex, 3% moly) as it's cheap and available here, and I've never had a problem (as in anything wear out) using it, but what i use it in wouldn't be considered an extreme environments. (sliding splines, ball joints and uni's)
Unfortunately my nearest CAT dealer is over 100km away.
