Question is caliper grease too light to use or should I stick with the white lithium grease?

No nay sayers so I guess it's ok to use

I used Mobil 1 synthetic grease on mine. 60k miles later I had a chance to look again and it still seems fine. I've used basic wheel bearing grease before on clutch forks and splines and after inspecting a couple years later it seems to turn to gunk.

I'm going to use the caliper grease I will check on it when I take the transmission out again in a few months.
