93 gas

93 octane will not give you better gas milage. It won't give you more power, it won't do anything except drain your wallet faster.

93 octane is for forced induction cars or cars with high compression. The GT is neither so 87 is perfect.

You actually make more power with 87 octane. Don't beleive the "Higher octane" is better marketing strategy.
