I've been running regular 87 in it and haven't had a problem with knock or anything so I didn't see a reason to go higher. Same with my Dad when he had his Grand Prix GXP. Been considering going up to 91 to see what the difference is and if I like it better. Probably next fill up.

93 in the 05 and 87 in the 03. When I get my Camaro or Challenger I will run mid grade - 89.

I have an L36 n/a with an Overkill PCM tune and a 3 degree advance so I must run 91 or better octane... I did however always run hi-octane, I find it keeps the motor cleaner and less build up over time...
