I think the water/jokenol mix is what is corrosive. That stuff will leach the copper out of brass jets and leave green residue permanently to the alum in the carb bowl. I drive a ways to a gas station with pure gas and pay the extra cost - it's worth it.

As for the F-33 Bonanza, they are also aerobatic. I watched Pat Epps do an airshow over his brother's airstrip one day as a thunderstorm was rolling in. It was maybe a 1000' ceiling and he was doing hammerhead stalls. Impressive but stoopit. he made it down before the first gust hit and the subsequent bottom falling out, but not by much time.
