Premium Fuel?

[Tupperware]

Car information at cars.com (and others) says premium (91 oct) is required for the GT. Is this correct?

EDIT: And yes, I mean the Mustang GT, not the GT GT.

No, regular fuel is fine.....but premium won't hurt......

Unlike the Mach1 and Cobra from 2004, the 2005 Mustang GT is an 87 octane car. Then again, it is still the entry level V8, it should run on regular!

It is interesting that my Ford Mustang GT owners manual states that Premium Fuel should not be used because it could increase rough idle, etc. Stick to regular and don't use any additives.

You must run this vehicle on 87 octane only.
