Probably the best grease I've seen is BR-2 (Beryllium Dioxide grease).  
It's a low consistency  grease designed for high pressure, low RPM 
applications. It has a very low coefficient of friction.  To quote the 
add,  "Dow Corning® BR2-Plus Multi-Purpose E.P. Grease is a lithium-soap 
grease suitable for use over a wide temperature range; good resistance 
to oxidation, hot and cold water and good corrosion inhibiting properties."
The White Lithium grease is still a very good "all around" grease that 
is stable across a wide temperature range and I've never seen it harden 
or dry out...yet. That said, my operating conditions are a very small 
sample of even those on the reflector.
