      According to the MSDS 3 in 1 Household Oil is highly refined 
naphthenic oil with some naphtha added,  3 in 1 Motor Oil, meant for 
electric motors is highly refined paraffinic oil again with some naphtha 
added.  I think it is the small amount of naphtha that makes both 
penetrating oils.  The 20 weight electric motor oil is de-waxed.  The 
MSDS for 3 in 1 Houshold Oil AKA Multi-Purpose Oil says nothing about 
whether the base oil is de-waxed.    Now, Kano Labs Microil, described 
as an instrument oil and recommended for typewriters, is about a 50-50 
mixture of naphthenic and paraffinic oils but using different refining 
techniques.   Also, whatever was in 3 in 1 oil in the past its likely 
something else now.   BTW, 3 in 1 is made by the WD-40 company.
