I think super lube is the best lube aswell, but how much would you use and would to much be a bad thing. when you say "dont remove the inner workings" i get visions of springs and pawls flying all over the room?
these ratchets dont seem to care if you put too much in, as they arent a true fine tooth, they are dual pawl coarse tooth, which makes it fine tooth. one of the ratchets i couldnt get apart, i packed like a bearing, grease in palm of my hand, and packed away for about 20 mins. i am confident a good amount made it past the small gaps and into the gear/pawl mechanism. it works great, but the few i did get apart, and cleaned then relubed are the smoothest by far.
what i mean by not taking the inners out, i mean not disassembling the inner pawl mechanism. you can pull it out of the ratchet body, but leave it intact. there is no risk of any bearings or springs flying out until you start really disassembling the inner mechanism. in my experience, there is no need to fully disassemble, you only need to pull the outer nut, and slide the insides out in one peice, spray with brake cleaner a few times, lube and put back together. a monkey could do it, nothing comes apart, no springs or anything to deal with.
BUT, your ratchet looks to be in very good condition. all mine are much much older models, like the one in the link i posted earlier. they needed a thorough cleaning and lube job. yours may not, but i do not doubt that it would benefit from the grease treatment, as opposed to an few drops of oil. its actually fairly difficult to get any lube to get into the mechanism without disassembling. soaking would be the only way that wouldnt be a pain in the ***.
if i had YOUR ratchet, i would attempt to get the nut off, if it fought back, i wouldnt pursue it very far. i bet yours will come apart easily, but if not just use it as is with a soak in oil of your choice. after the soak, take a wad of paper towels, and smack the ratchet into your hand, selector side down a few times. this will get the excess oil out, and leave a non-messy ratchet for use.
