Nice to see that the myth of using higher octane to solve mechanical problems is still alive. :S
30+ years of automotive engineering disagrees with you.
I qualified my response by saying "ping" from pre-ignition can be cured by higher octane. Why the pre-ignition is occurring is hard to diagnose, but likely it is from carbon build up inside the combustion chamber.
Higher octane fuel will not ignite until a higher in cylinder temperature is reached, such as an actual spark event nor just a "hot spot".
In my case, anecdotal evidence proves I am correct.
