      Mustang Octane Anyone?

      Got it posted in Emergency Room, but no replies. Someone must know what octane a stock mustang GT requires.

      What year? Most likely they are going to recommend Premium for any Gt or performance model.

      My best memory says 91 octane, but then again I'm actually remembering back to 1990 to when I carpooled with a friend in his then new 5.0 convertible. Probably the best thing to do is visit a Mustang specific forum with lots of Fox body owners, like over at www.stangnet.com .

      Do you still believe in all the things that you stood by before? Are you out there on the front lines, or at home keeping score?
      Do you care to be the layer of the bricks that seal your fate? Would you rather be the architect of what we might create?
