does anyone use 100LL av gas ?

Exactly what additives...How is it bad...??

I am not a chemist so I don't know the names of the chemicals. Post 18 touches on some of what I was talking about. I am not getting into another discussion/argument like last time. I just threw it out there. It's not the same as automotive fuel. You can find any details you want online and make your own informed decision.
