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.

40 years no maintenance! Try that with a China fan. She's gonna gain 100 R.P.M. after service.

Not self promoting here. But, this photo gallery has a breakdown of a similar motor and how to change the wicks and grease. Removing the worm collar and what-not.
Antique Emerson 6250-AF 10" Bronze Blade Pedestal "Floor" Fan Restored

Just one example of a photo. Changing wicks for example. All four of them!

Thanks for the tips Geoff. Came apart just as you described. I couldn't get the oscillating adjustment knob  to come off. I removed the set screw, but it would not slide off so I just lubricated with oil. Used the "Red N Tacky" grease for the gears from other post recommendations.
I did have a question about this screw (see image). Is this an adjustment screw of some type ? 




Here's a pic of the 2450-G after lube and cleanup.. pretty good shape for a 1940's fan

That screw holds in the bottom wick. I think there is one on the front too. If I were you, I would replace all four of the wicks. You can poke most of them further down and pull them out through the bearings, but there might be one or two that have to come out the opposite way from the bearing, in which case you can take the opposite wick out through the bearing and then push the other one out away from the bearing. I probably could've worded this better if it was earlier in the day, but hopefully you can understand what I'm saying?
