It's sump oil. You could return it to the sump, but it's been vaporised and sent out the PCV so there's no telling how good it will be at lubricating anything.

Not sure if you recall - I certainly do, they were a complete pain in the tail if you were a motorcyclist - the black pools of oil at every set of traffic lights, decades ago. It wasn't just because there was a Triumph TR7 in town, it was because PCV was generally just vented to atmosphere, often creating slick patches in the centre of the lane at traffic lights.

used engine oil will clog up your diesel fuel filter from all the soot/dirt thats in it.

The fuel pump doesn't need diluted sump oil to "help" it.
You could however make your own return system from the catch can back to the sump.

I tried the old wives tail of adding a couple hundred mls or so of 2 stroke mower oil whenever I filled up (curiosity and all that).

Reached the conclusion that any changes were probably from the placebo effect and I doubt it made a difference to anything. I am sceptical of fuel additives in general though.

Sump oil would be the last thing you'd want in your fuel.

Or you could rip out the catch can so the oil is burnt in the combustion process.
