Hi
I have a monte carlo ss with the SC 3.8
It requires premium fuel, 91 minimum. Next weekend I will be near a station that sells 100, and 105 octane fuel. Would a tank of 100 or
105 be good for the car, or cause me problems? If RITA causes fuel to go back up to over $3, the high octane fuel cost wouldn't be much more than 93 octane.
