Fan bearing lubricant was Re: WD-40 (again)

[Chuck Guzis]

I did some research among the antique fan collectors on the web.
Here's what's been recommended, in no particular order:

1. SAE 20 *non-detergent* motor oil
2. Turbine oil (ISO 32 SAE 15)
3. 3-in-1 Electric Motor Oil (SAE 20) *note* Not the multipurpose "red
can" stuff, but the blue can motor oil.
4.  Royal Purple Synthetic INDUSTRIAL oil ISO 68 ~ SAE 25
5.  Lithium grease in an aerosol spray--what I use.  Be sure to shake
the can before application.

FWIW,
Chuck
