I have read in the owners manual that you can safely run Regular unleaded.
Check your Owners Manual to be sure!
However,it does cause some slight pinging, which isn't worth the approx. $1.50 per tank savings.
Also, I have read somewhere on the message boards that running octane higher than 91 is Not recommended.
Many stations here only offer a choice of 87, 89, or 93 octane, so I personally use 89.
Enjoy the ride!

In using 89 octane does the phrase "possible engine damage" ring a bell? Do you think the pinging sound is just innocent noise? I haven't heard or seen that 93 octane is bad. A lot of GT owners use it. Look on the inside of your gas door. It says use premium gas. I'd hate to see you damage your engine by using 89 octane.
