But my dealer says nay, nay! No 0W-30, no warranty! - just to be clear, I guess due to the OPF we are bound to the LL-04 specification.

Thus I am being forced to use this:

Still a great oil... but somehow it bothers me.
Just curious, how would the dealer know what oil you used?
They do the work when they service the car... thus the see what oil I bought and asked them to use.
