What was the root cause of your issue? Did you have a loose spark plug, or pre-detonation occurring?
I'm a little confused here, as just 'changing plugs' and using '93 oct' would resolve such an issue as rattling below the 3K RPM mark, especially without determining the root cause of the issue.

What I was trying to say is that I resolved similar symptoms that our friend described as:
"In my case, I notice a intermittent pinging when I accelerate hard when at lower RPM. Not something I do a lot but from time to time you have to react to other "drivers" and a gear change is not practical. Once I get over 3K RPM, all is good. Engine pulls to redline no problem. This does not sound like rod knock to me (not to mention I hit redline daily and have not had any parts try to escape yet). Also, it has been happening for some time and does not make any noise when out of gear at any RPM."
After spark plug change and my second 93 oct tank, pinging noise disappear. Good luck!
