I dug my Singer 111W155 out yesterday, and am pressing it into service.
When reading the manual, it has several lubricants listed, most of which
would probably be hard to find. I haven't looked yet at the sewing machine
or fabric stores.

Is there a big difference between oils, say like Singer, 3 in 1, Lucas gun
oil, etc? I know there's a big difference in oil and grease.
