Question for you Crossfire Owners
My dealer also told me to use premium. Maybe somebody can confirm this though... he also said that even though the price of the premium is higher, it burns differently and produces more MPG.
Just a sales tactic? I really don't care but I was curious about this statistic.
He could have told me to run cow dung and in the state of euphoria I've been in since owning this thing, I would believe anything.

1. They forgot to add color to your paint.
2. They forgot to put a roof on it too.
LOL- It's a beautiful roadster... :lol:

There are some cars with what I think they call dynamic timing so you can use any gas while losing 10-15% HP with 87 octane, but as far as I know, the Crossfire really has to have premium.
When I took delivery of my Crossfire, the moron lot boy at the dealership put about 3/4 of a tank of regular in it. I noticed quite a bit of hesitation and stumbling, especially in stop-and-go traffic. Adding octane boost didn't really help, but once I'd managed to burn off that tankful, the car ran much better (flawlessly) on 93 octane. So I can attest that regular isn't going to make it in the Crossfire.
This engine is 10.0:1 compression ratio. With that much compression you have to run the higher octane fuel to prevent pre-ignition that will damage valves and pistons.
If you are hearing "pinging" (especially when accellerating) or the engine tries to keep running after the ignition is turned off you are experiencing "pre-ignition".
