I would toss it ( recycle ).
What does air tool oil cost? Pennies. Is it worth putting this
*stuff* into your tools to save a dollar? Only you can decide. I
wouldn't. I would throw it away and buy air-tool oil, which I have.
A little goes a long way. A quart will last years.
Refrigeration mineral oil needs to be used in a sealed system wtih no air or
moisture. It absorbs moisture, and won't be good for your air tools. Likely
to cause corrosion.
The quart of oil, it's been awhile since I bought any. Five bucks or so.
Maybe you can find a shop that can use it, still some R-12 air conditioners
on the road. I know... I drive one every day.
R-12 MINERAL oil does not absorb moisture. POE R-12 compatible oil (aka
'Ester oil') does. So does PAG oil for R-134a systems.
Still, air-tool oils have properties (anti corrosion, surface tension,
seal compatibility etc.) that R-12 mineral oil isn't optimized for. I
wouldn't use it in any air tool I cared about.
