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
