This is  probably the crux of many misunderstandings.
Though I'm nowhere near a fuel  specialist, I see a distinction
between ignitability and burning slower.
A  fuel can have lower ignitability than another fuel, but once
ignited, both  burn at the same rate.

I'd venture that higher octane equates to  decreased ignitability,
not slower burning.
But then, I don't know much  about this subject.  <G>


You have sussed out the important  distinction, Bruno.
