Has anyone tried to use Super Unleaded on their cars? Did it make any difference in performance for you?

Only from other experiences w/ other cars, the car has to be tuned for the 93 to help in performance.

Not at all, I filled up with it the other week (Road & Track recommended 91 octane for the 6, whereas the manual says 89); then I filled it up with 91 just a few days ago, not a slight bit of difference.

Definately not worth it in this gas price hike.
