Is there a preferred light-weight motor oil that may be used in Wurlitzer
gear standards?

Thank you,

 [ Gears that aren't enclosed in an oil bath should be lubricated with a
 [ suitably viscous oil which clings to the gear teeth and doesn't drip,
 [ such as SAE 90 weight with no additives.  (Additives aren't needed at
 [ moderate temperatures and they're likely to make the oil harden with
 [ age.)  Very slow moving shafts should receive a grease, and high-speed
 [ shaft bearings probably should receive the same oil as does the electric
 [ motor (SAE 50, non-detergent).  -- Robbie
