I do very much like to fill in those gaps so when pointing out when I'm wrong by all means feel free to explain at length.

You don't need a million $ or even any experimentation. Just go online and find out how the various cylinder deactivation systems work then get back to us.

NONE of the materials I've read indicate "cycling" of dead cylinders amongst them all as a means of dealing with your speculative "problems".

There IS a system that cycles dead cylinders, and that is the Cadillac Northstar limp-home mode for the circumstance of coolant loss. It does not work as an economy device.

It is not unknown for car engines to have experienced dead cylinders, mostly due to ignition problems. Cylinder heads didn't crack, head gaskets didn't fail, etc. etc. etc. Power and economy went down, though, and pollution went up. That's about it.

P.S. GM says wear differences between live and dead cylinders is a non-issue.

Not for something as trivial as this. not enough hours in the day. I wanted to get you to chime in with what you know instead if just "you're wrong" and nothing more... to end the speculation

Hey, I did the research and put it ALL up once upon a time, where it appeared to be ignored. I used to do that a LOT. Now, I refer people to Google, because that is largely where my research starts and alls y'alls have the same access to it as I.
