I have an unopened quart of NAPA #209500 mineral
oil for old car air conditioners that use Freon R-12.
is it OK to use in air tools?

I would toss it ( recycle ).
What does air tool oil cost? Pennies.

That's more than my air tool costs.

I would throw it away and buy air-tool oil, which I have.
A little goes a long way. A quart will last years.
