Antique Electronic Supply has something called "Phonolube" "Light bodied grease made of polymerized oil specially developed for the lubrication of small geared mechanisms. Retains its viscosity over a wide range of temperatures"
I prefer light oil for the motor and idler wheel shafts. I have some of this but I bought it locally:
