RE: gas and octane
What people fail to realize, is that octane does nothing more than increase gasolenes resistance to burn. Which is why cars that run boost, advanced timing, and high compression need higher octane, to keep the gasolene from pre-igniting, or also known as detonating, or spark knocking.

look in your manual, some of the early GTs said 89 octane and the later ones said 87, the mach and cobra take premium

Where the hell did this myth that higher octane makes your car faster come from?
Octane is nothing more than the resistance to pre-detonation. aka pinging aka knocking.
Use what the manufacturer recommends. 87 or hell, if you want to spend the extra 10 cents/gallon, use 89. Premium or race gas is a waste of money on a stock GT.

RE: gas and octane
i run 93 oct i have tried 100+ avgas but it did nothing the 93 give enough fuel milage difference that it is cheaper to run over 87 when 87 oct reaches $2.00 a gallon. i can get another 30 miles out of a tank with 93 over 87

I have a 2000 V6 Mustang that has never been happy on anything but premium. Probably something wrong somewhere, but hey, feeding it something that doesn't make it ping loudly is cheaper than fixing whatever underlying problem there might be. Bottom line, feed the car what it wants. If it doesn't ping on 87 in normal everyday driving, than that's all that is required, and feeding it premium under such conditions will not make a bit of difference.
