AvGas
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.
