With pp 5w20 in there just as you reach cali your car break downs due to lube related failure.
Is m1 going to pay? Is penn going to pay? Is G37 going to pay ?
A strawman doesn't strengthen the argument...and besides, if you are on a long distance drive with a known oil burner, then you'd be foolish not to take some top-up oil with you.
do you need need to buy your jack, tyre irons and spare from them as well ?
ASTM D6922 is there exactly for the reasons that you quote...and here's what it offers...

Every oil on the shelves has to be able to be mixed with 7 reference oils. Cooled to a gel temperature (not specified, it's the temperature of the new combination), heated to 150C, cooled back down to the gell temperature, and heated to room temperature. It's not allowed to split like salad dressing, nor drop out a precipitate.
That's all that the miscibility standard offers...nothing about staying in grade, or meeting cold temperature viscometrics.
As to who's liable if your mix doesn't play well...nobody but the mixer.

There are many fine finished oils. I pick one that meets my needs and stick with it. If I have to top off I have 4qt left in my 2nd 5qt jug to top off with for the entire oci.
I am happy for you but afraid you are not providing a persuasive argument against careful and thoughtful mixing.
How is it careful and thoughtful if you have no idea what the end result is, just guesses /
And a strawman that is....almost textbook
