You can add a bit of carrier grease as well if you need to reconstitute it past re-mixing it. Some understanding is required though. The grease you use cannot be chosen indiscriminately. You should match the original grease chemistry as some grease bases are incompatible with others. The MoS2 isn't soluble in the grease carrier, it is only suspended. The moly won't degrade, just the carrier. In service, the carrier is expected to dry out and leave the solid lubricant. The only thing the carrier can do wrong is wash out and take the moly with it. I used to make my own moly paste back in the olden days when the BMW specified Straburags NBU30 PTM proved not only uber-expensive, but totally inadequate for the task of staying on clutch splines. The well-considered consensus then was that 30% moly plated the parts out better than 60% did. Just use a bit more to get the required moly content. My own recipe was to compound dry MoS2 into Wurth Sig3000 grease for a 30% solids mixture. After that I used a mixture of Honda 60 with various compatible greases until Guard Dog GD-525 came along. It is still available from T.S. Moly, but I expect I"ll transition to the Locktite product when my stash expires or is used up. GD-525 is what we used on @Uncle Phil 's rear wheel when we put a tire on it during BRG. His splines were totaly wiped clean of lubricant when the wheel came off and he can report at tire change how the GD-525 did (or did not) stay on the job.
