When you ask about manufacturers changing over to high octane engines. I would suggest that all that would have happened was that they altered the ignition timing specs?

I'll have to defer to you on the technical aspects. It's all beyond my ken, but I know that the British Army had to change over to North American octane rated gas when the Lee and Sherman tanks began to arrive in the Western Desert. The Army had to borrow high octane aviation gasoline from the RAF to fuel them.
