Octane questions

Mar 31, 2005
I know this has been beat to death, but I am curious what others with more knowledge have to say.

I have done some research on 'pinging' (ie: detonation and pre-ignition) and am still confused. Does the computer in the FZ allow this

Sure seems to me like that is what the computer is supposed to do, but I really don't know. I cannot tell if I have ping when driving I-70 West (with 87); but I do notice a climbing difference when I run the 91 octane vs the 87. Am I giving into the power of positive thinking, or is there really a difference?
