All i got from that article was they want you to buy expensive gas so they tell you how bad av gas could be.

I posted different views so everyone can read for themselves and decide what they want. I have run it and never had a problem. But, no matter what the subject, there is always another opinion. I never burned a valve or piston so I would run it again. I might've run better on race gas and been more consistent. The same goes with running alcohol. There are people that say it is hard on parts, but if you prepare the car for it's use you will probably be fine. When you take short cuts and don't think it through properly is when things go bad.

pushing it at 12.5 to 1, if ya get caught somehow its a $25000 fine

one of several/many differences is that av gas has an anti icing agent added to the fuel.
