High compression is just that, a knock sensor to retard the timing will help but the mechanical atributes of the engine don't change.
I bought my crossfire to drive it like a sports car so I'm sticking with a minimum of 91
Regular may not hurt if you are going to baby your car around but then what was the point of buying it?
Dittos: If I wanted to use regular, I'd kept my Honda Insight. As for saving 20 cents.
