Am cleaning my old stand fan for home use. I suppose grease is to be used on the sleeve bearings but then again, why can't I use HDEO ? There's no felt wick, though.
Grease or oil for stand fan?

You are unlikely to be able to lubricate a sleeve bearing and have it help for any period of time. I have tried before, even had the shaft vertical overnight so the oil I put on top would run down. It helped for a few days. Then back to the noise it had been making.

I re-oil small boxer fans with ATF.
The 3-in-one electric motor is correct, but I've also found that Hoppe's gun oil will not "gum up" like most conventional oils in this service will. Add a felt washer if you want to retain a little lube reserve, it will also keep some dust out of the bearing.
Non detergent 10 weight oil. Detergent oil stops the wicking of the oil through the bearing.
Always oil in a sleeve bearing, and grease in a ball bearing. If it is preventative, use a very light oil. If it has already worn the bearing and is making noise, use a thicker oil. It will not be drawn through the bearing well and need reapplied more often but once you have the wear you need a thicker film to (try to) keep the wobbling to a minimum.
I've had great success relubing sleeve bearings in everything from HVAC to computer fans, box fans, appliance motors, etc. I've had no problem using detergent oil, even a decade later in some cases but IMO that's around the outer limits of how long it'll be till it needs relubed again unless there is a substantial oil reservoir you fill. w/o a reservoir it's usually more like every 3 years depending on running hours and amount of wear already present.

Thanks, guys.
