I have always used 89 in my 02 V8 Sport without any hint of a ping and with excellent performance. I once tried 93 octane with no change in performance so it was 89 from then on.
i use 93 as well and have only come across 91 once also at a 7-11out in cocoa beach, but even that is a drive for where i live at. i hve only used 91 2x on my car and my wife put in 87 or 89 1 time b/c she believed gas is gas crap until i showed her the difference...
