Very interesting read and not far from what I expected. For me, my filling station only charges .10 more per gallon, so I don't think it overly beneficial for me to "risk" it. I can certainly understand those who will, but I agree with Jeep2Xfire.

Quick story when I was buying mine, the salesmen said you don't have to run premium, you can go with regular. When I call a couple of maint shops, including the dealership I was buying from, the maint folks said you'll experience performance issues and will get the check engine light after a while.
