Has anyone run the "new" Shell 93oct gas? I've run it a couple times and it seems like the car is a lot more sluggish after the fact. Anyone else have any problems?

mrvax said:If you do need hi-octane gas and you use it, you will lose some power. Not all the fuel will be burned. Stay with 87 unless you are pinging....then fix the pinging problem.
Running a S/C, nitrous, advanced timing or hi compression are the only reasons to use hi-octane.
