But, but...we need to know the constituent that adds the magic aroma to 
the stuff.  The rest of it is just lubricant, but oh, the smell we want to
bring back!

I recall that the maintenance instructions for the Teletype machines used
as consoles on DEC minicomputers said to use a 50/50 mix of engine oil and
STP.  I don't remember now if they said 30 wt oil or 20 wt.  Seems like
30 is a bit too viscous for use around the selector.  This instruction
came from DEC, not from Teletype; and I have no idea if it was a good idea
or a bad one.
