Did you look in your owners manual? You'll find a lot of information about your car in there. The 3.6L requires 87 Octane.

READ your owners manual or look on the inside of your gas cap door! The 3.6 liter is a DI (Direct Injection) engine, therefore, I use 91 Shell V power in my daughters '11 ... if need be ECU will compensate.
