Perhaps I should have said "very thin with high viscosity",
which is perhaps a redundant way to express it. Anyway,
I meant "runny".

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.
