Aren't you glad you asked?
(Gotta get a popcorn machine next to this desk...and a small beer cooler beneath!)
BTW...Until I read down through these responses, the memory that came to my mind after reading Santiago's question was of a time many, many moons ago. We were traveling, needed some roadside help, was towed to a 2-bay station in the next town. Mine was a relatively simple, minor problem. The car in the second bay apparently had a front wheel bearing issue. The mechanic was sitting on the ground, ball bearing in the one hand, a handful of grease glop in the other, and he was packing massaging the grease into that BB like Helga working out the tired muscles on your back! Dad and I had done the simple under-hood things in our garage when I was growing up, but this bearing 'massage' was a first for me!
So I just assumed there was some sort of "bearing grease".
I'm somewhat puzzled by LaBelle 108 and the like in an unsealed BB. I'd have thought gravity...(Sheldon's nemesis on moving day)...would've worked only in the short term for a viscosity that thin, and its migration potentially another maintenance/collateral problem. Since I also have Red 'n Tacky, I think that would have been my first choice from my memorable event of yore, and not having read these responses. Then again, point contact light-duty bearing lubrication is not in the same league as sleeve bearing heavy duty lubrication.
Hey, what do I know?...I come here to learn, too.
