[GreenKeys] 7470 oil

[David Christ]

If you have a buddy at the FBO have him give you a few of the cans/bottles after he has used them.  Turn them upside down and let them drain for a day or two and you will get a surprising amount.

The needed it for all sorts of applications and the Labs experimented with additives.  This is very old (I will post a link later) but at the time they found that mineral oils spread out and vegetable or animal oils did not but oxidized to quickly.  I am sure there are better materials now since synthetic oils to take the place of sperm oil for fine machinery was developed long ago.
