thanks Jim. The newer chain lube i purchased isn't the same as old
type which was thicker. Was looking for something else (on hand) I
could use. Too many spray cans in the shop!

Light or heavy mineral oil is same or similar to the sewing machine
oil? I'd think rigging up a small tube and drip some of that in would
be "easy".

IIRC, someone in the thread I linked to used PB blaster which AFAIK,
is not the right stuff.
