Back in the day, my dad (an engineer) said "There is sliding contact grease, and rolling contact grease." Sliding he used black lithium (like for steering linkage), rolling he used "long-fiber" (no actual fibers, it describes the appearance as you scoop out a bit of it) grease (for wheel bearings). Now, I buy a tub of grease, and it indicates it's good for everything. White lithium, I perceive as a bit "cleaner", comes in spray form, nice for door hinges that are visible.
