I have a Emerson 2450-G that has not had any maintenance in 40 years, but we use every summer. 
I assume both of these tubes (see image) are for lube/oil - How much should I use at first, then every year? (I have the 3 in 1 blue)
Should I lubricate the external oscillating mechanism with oil or grease?
What about the internal gears, Should I dis-assemble and lubricate those or is it better off leaving it alone?

Anything else to keep this awesome fan running forever?

Thanks in advance, Jeff

 If the fan has worked for 40 years w/o much maintenance , I'd take the gearbox off the back (3 screws) take it apart (3 more screws) clean as much of the old grease out as you can. If U want to get aggressive , 1 or 2 screws backed out will allow the osc. adjusting knob to slip off of the shaft and you can clean the gears and gear case real well. 2-3 drops of blue can oil on the working parts of the adjusting knob will loosen it up so the parts slide on each other easier.10-20 drops oil front & back rotor bushing and your fave grease for the gears in the gear box. U don't hafta pack that case full of grease just a liberal coating on the teeth and the holes in the casting where the 2 gear cluster spins. Be sure not to lose the fiber washers in the gear box that keep metal from spinning on metal , or replace them if they're missing or rotten.. Hope this helps.

I have given a couple little Emerson's as gifts & folks run them night & day and hey can just run dry, so a few drops of oil now & then is all you need after a servicing
