S-A coaster Q
Howdy. Newbie. Well, OLD newbie.
I just scored a very clean (outside, haven’t opened it yet) SC coaster hub, dated ‘69. Since it’s several decades since I’ve messed with coasters, I thought I’d check videos. Hmmm. Guy tore it apart, cleaned everything up, and then greased the crap out of everything on reassembly. Nary a mention of the oil filler cap or what goes in there. We used to pump ‘em full from dad’s squirt can that was probably 30 wt., not the best, I’m guessing. Since I’d like this to last at least as long as the years left to me, advice please. Grease? Oil? Both? And what?

Alrighty it's a bit quiet here so I'll throw this in - I've read all sorts about coaster hubs: oils, greases, even vaseline (but I don't think it's particularly 'high temp').
Although I have read that too much grease can gunk up the workings somehow.
I've come to believe it probably doesn't matter what substance is used. Of course it might matter very, very much to someone. But probably not the hub.
I have an old 3 speed sturmey coaster hub and I put oil in the oil side and grease in the bearings and coaster brake parts. It hasn't complained yet.
The bottom line is, the more often you ride it, the more often you'll need to squirt something in there. If it's lots of miles/km's, then occasionally you'll need to break it down for a service.

I use 5W30 oil. Read somewhere that’s roughly equivalent to the original S-A gear oil.

I've had exceptional luck with 00 grease for the internals, and marine grease for the bearings. This is more or less equivalent to what SA uses in their modern hubs.
EDIT: Disregard, didn't realize this is a SC coaster brake. Grease it up.

On the coaster brake portions I use Lucas high temp red grease, but you could get away with something like the Lucas green standard lithium grease if you're not riding the brake down big hills.
For the bearings I use the Lucas Green lithium grease.
At the oiler cap, I use 20 weight oil, specifically 3-in-1 blue bottle.
