No. They sell this stuff called "sewing machine oil" at a place called
the "sewing machine store". It's extremely light, doesn't gum, doesn't
drip, doesn't stain, etc. It's the right material for the purpose.
Unless your goal is to make the problem worse, either find out what it
is (hint: not a hardware store item), or just GO BUY SOME and use the
right stuff.

Never heard of it.
Q: Is sewing machine oil thinner than penetrating oil?

It's clear that you're not qualified to "fix" the machine you're
tinkering with. Do yourself a favor and pay someone competent.


Hey, cool down Dave.
Sorry if you feel offended, just thought I'd bounce you back, fair enough?

To answer your question, no, sewing machine oil isn't thinner than
penetrating oil. But it's the lowest-viscosity oil you're likely to see for
a consumer application that still has the ability to lubricate. Penetrating
oil, like WD-40 and lots of other oily things, has almost no lubricating
ability at all.

Any sewing-machine store will have it. Buy the most expensive kind you can
find. It's the only thing to use on your sewing machine.

Having said that, I'll tell you that I cheat a little and use Starrett
Instrument Oil, which is just slightly heavier, on the bearing surfaces in
my old Morse machine that I have identified as high-load bearings. I've
gotten away with it for over 20 years now, oiling about once a year, and it
seems to do a fine job. But I would not use it in the lightly-loaded bearing
surfaces that move at high speed. Unless you have a very good sense of
bearing loads and lubrication, stick to the sewing machine oil throughout.
