     I can't quite make sense of the above, thin and viscous 
are opposite terms and its not at all desirable for oil to 
evaporate whether it leaves a residue or not. The correct 
oil depends on the kind of mechanism.
     I suspect sewing machine oil is a highly refined 
instrument type oil meaning its free of acids or other 
contaminents.
     One of the main problems with lubricants is that they 
accumulate dirt. No matter how long lived the lubricant 
itself is it will get gummy from the junk it picks up. The 
only cure is frequent cleaning and relubrication.
