Are you familiar with Boyle's Law? You compress a gas and it heats? Higher compression of air/fuel lowers the detonation point. If your air/fuel mixture detonates at the wrong time in an engine, you will get damage. Higher octane fuels take higher temperatures to detonate.
That's why higher compression engines REQUIRE higher octane fuel, as the manufacturer will specify. Run without it, damage your engine and try to make a warranty claim. Good luck with that!
