And you mean "inside the combustion chamber cooling", yes? As opposed to what everyone else is focusing their attention on. More pure gasoline in CC could very well have caused more heat INSIDE the the cylinder, which the piston and rings transfer to the cylinder, and thus the damage shown, yes? Even without a technically "lean" condition, gas burns hotter than oil.
I'm speculating here, but I think I've got it.
Also not agreeing or disagreeing with anyone. Just trying to understand what you're saying.
