I am reminded that there are people out there who collect used motor oil, reprocess it and sell it. I recall discussions in drivers ed years ago on whether reprocessed oil is actually better than new oil.

As a chemist, I know that used motor oil can be processed to be as good as new. But one wonders if the market will pay the cost of fully reprocessing it and adding new additives after contaminants are removed.

It is tempting to filter out the solids, remove corrosive acids (from oxidation), remove any foreign color, add additives and package. Vacuum distillation would be a lot better. (That is the way motor oil base stocks are made for sale to those who make new, virgin motor oil.)

Do they check for volatiles? If someone puts diesel fuel or kerosene in the waste oil bin, do they detect it and remove it? Or do they simply package it hoping you won't notice. Of course evaporating oil is one way you would notice.

I think the reprocessed oil mostly goes to fleet operators who maintain their own vehicles. But you would not be surprised to find some in a discount store and every oil change shop probably knows where to get some at a very good price.
