I stick with Exxon or Mobil (same) if they're around....if not then Chevron (since we don't have sunoco out here in az).......
Look at the fuel panel.....it says a min. of 91....so if your stock, then its recommended to use a min. of 91. If you're chipped, then you must use a min. of 91. The chip itself retards timing. Another reason why you need 91 octane when chipped.
And if you're pinging with 91 still...then you have another problem than gas.
P.S. I can't wait to move back to the East Coast were gas is 93/94 octane, not this Westcoast 91 crap.
