I use reel butter or that red stuff. Mostly cause I wanted to try a a grease that was specifically made for reels, and so that’s what’s in my drawer right now.
But ya know what? I’ve experimented with several different greases and oils, gun oils, ATF, ballistol (one of my faves for everything under the sun), synthetic motor oil, conventional motor oil, gear oil, high temp machine grease like you’d grease hub bearings with. Only thing I’ve found that’s not worth a damn is white lithium dielectric grease, the stuff that looks like a cream. If the super lube y’all mention is the same stuff in my toolbox, that’s a dielectric grease too, but obviously not the same stuff. Mine is kind of an opaque colorless grease.
