There is oil / gas dilution and add pack depletion to name just two.
If something can be done it doesn't always mean it should be done.
No it is not. I easily get 10K on Castrol edge 0W30 european formula and I have the oil analysis from Blackstone labs to prove it.

pull a sample send it and read the data you tell them the car you have the oil you are using and how well it's doing. If the oil and it's additives are not breaking down then it is just as good as the day you put it in the hole.
