Read the Gasoline FAQ link I posted previously... no, really, read it. You're still equating the octane rating (RON, MON, AKI) with initial auto-ignition under temperature and pressure. It is not the same, as I said in my previous post.

Octane rating conveys what happens once the fuel has been ignited, not how difficult it is to ignite the fuel initially, according to the FAQ.

I was under the impression that auto ignition was only a result of temperature and pressure (that and carbon deposits). But looking closer at the below definition, I see that octane rating may only be in reference to a spark-ignition system

I'll spend some time reading the article after I get home from work and post back later when I'm more informed. I appreciate you taking the time to help.

The above quote has not rendered any light, just a bunch of heat. Not one piece of substance here, just an opinion with no backing.
