Transmission oil

["W. Ray Gibbons" <gibbons@northpole.med.uvm.edu>]

Philip Ethier advised use of *non-detergent* 30W oil in Spridget
transmissions, to save the synchros.  I have an early ribcase transmission
in my bugeye.  I read all of the relevant manuals, and don't recall a word
about non-detergent.  I know I am using standard detergent motor oil; it
may even be 10W30.  I believe the manuals I read said this was OK.

What is the net wisdom on this?
