Engine oil consumption issues

I imagine that this is something that Volvo has checked out as they have the tools to do so. It would be nice if they shared their findings, but I don't expect this to be happening anytime soon.

If, however, the USA suddenly saw great value in running diesel cars then it would all change.

I agree that it is probably very tiny amounts of engine oil but, then again, there are only tiny amounts of diesel getting into the combustion chamber.

It's more about the fact that this impure mix can easily be combusted in each cylinder 50,000 times over an hour's drive.

My wife's 2015 V60 D3 is currently quite capable of getting through 0.5 litres of oil over 500 miles. Imagine the amount of smoke and soot that 0.5 litres of burning diesel might generate. If only a small fraction of that soot remains in the combustion chambers then it's a big problem.
