For the average car, driven by the average driver, on the average commute - your right. But...
1. My car's not stock
2. I don't commute with the car (ie.. drive 65 in the slow lane with my cc set)
3. Yes, I live where there is only 91 octane fuel (and crappy stuff at that)
so..
3. Why am I wasting my money?
4. How come there are "octane level" settings for tuning on our ECU's?
6. What kind of damage can I do to my SRT Engine? (in the long run)
7. They call it RACE GAS - because: "I FEEL THE NEED FOR SPEED!!!"
