I agree with all the posters here who say you need premium to get the most out of the car. I disagree with those who suggest you need to run premium to keep the car "safe," or that the car "won't like" regular gas (assuming you are running a stock tune). There is no increase in safety from using premium. The detonation margins are the same if you use premium or regular because the computer limits power output with lower octane fuel. The car will neither like or dislike whatever kind of gas you put in it--the car has no feelings about the issue. The PCM will simply limit power output with lower octane fuel. The DRIVER is a different matter. The DRIVER will most certainly dislike using regular gas after running the car with premium because the loss of power is SIGNIFICANT. If you are willing to live with it, however, it makes no difference to the car--either safety-wise or emotionally.
I run regular gas almost exclusively in the winter because a) it's a lot cheaper than premium and b) I can't use all the power on wet and snowy roads anyway. Why pay for premium fuel when you can't use the extra power anyway?
