I keep an old note from a proper auto engineer, it's quite lengthy regarding spinners & spline drive wheels, but the basics are...
Don't use anything containing molybenum disulphide (moly) or PTFE, don't use ordinary oil or grease
He preference was lead based additive in high temp grease (probably can't get that now)
Second choice was copper based which apparently had the benefit of anti-galling and good shear stress meaning it stopped overtightening of the spinner threads
(sorry but graphite isn't mentioned)
