+1 for the 3in1 oil. I used that for years on Sturmey Archer hub gears with no problems at all. Just the right viscosity I'd say and easy to apply through the lubricating orifice ( :lol ) with the can nozzle tip.
You're lucky it's the 3 speed hub and not the 5 speed. 3 speed was superb, but 5 speed best avoided imho.
