Oil pits on concrete floor

I recently pulled up a carpet and padding from my basement floor, and discovered that there are several small 'oil' spots or pits that have formed??? Can anyone directme as to how these form, and how can clean them?

I have also seen these on my garage floor?

Could this be from 'oil based' paint that as once on the floor?

Could there be any other cause?

Note: It's in a game room and we have never introduced any oil into the area.

Concrete roughly 40 yrs old - carpeting was probably 10 yrs old.

Thank you for any help!

Well, I'm confused. Do you have both pitting and what looks like oil spots or are you referring to the pitting as oil spots? I wouldn't associate pitting with an oil spot.

Pitting, aka spalling, is quite common in concrete. Oil spots could have been there for a long time and maybe the carpet was put down to cover the spots.

Neither is caused by oil-based paint.
