This is a neverending topic of discussion in this group.  If you're going
to use 3-in-1 I would suggest their oil for "large motors" that comes in a
blue and white can rather than the red, white and black can.  It's 20 weight.

I once used 30 weight oil, and it seemed to be a little too thick for things
like Model 15 selectors where the parts have to move fast.

I've taken apart some Model 14 selectors on Western Union machines and found a
green varnish-like substance on the separator plates causing the selector to
misbehave.  I don't know what W.U. was using for a lubricant, but Real Teletype
oil was not supposed to cause that stuff to form.
