[Shop-talk] oil

[phoenix722 at comcast.net (Mike Sinclair)]

My ancient small air compressor has a plug to check the oil.  I haven't used
it a lot lately, and decided to check the oil level, which is fine,
but.........seems to me I used to have a small container of "compressor oil"
for refilling, but of course, can't find it.  Is this a special oil, or would
any "motor oil" of the proper weight do?
