Internal hub gears take a pretty high load, as far as bicycle parts go. But the mechanism is quite similar to the innards of a quick change lathe gearbox, especially those of 20+ years ago. Straight-cut gears in a low-temp environment taking a medium load at low rpm's. I would suspect that 20 wt machine oil would work as well in a S/A hub as it does in a South Bend lathe.
