So… Super lube 21030 or Super lube 92003? 
From QA of Amazon:
“super lube 92003 silicone lubricating grease with ptfe” and “super lube 21030 synthetic grease”
“One is a silicone grease. the other is . . . not. (It may be a PAO formula.) On the Super-lube website (under Tech Data Sheets) it says, “There is no Silicone in Super Lube® Multi-Purpose Grease with Syncolon® (PTFE).” Although the name seems slightly different, on that webpage it specifically includes product #21030”
