Default MoGas Tips, Tricks, Concerns, How To

Let me know which of the above statements you disagree with, and I will find
a reference for it.
I stand by my statement that an overheated engine will be more damaged if it
is running lower octane fuel.


None of your statements are incorrect, they are merely irrelevant.

Low-compression aircraft engines were designed to run on 80 octane
fuel. Running fuel of higher octane is not going to hurt anything --
but it won't help, either.

87 octane auto gas is perfect for our low compression engines, and
certainly won't hurt them. Using "premium" (or, for that matter, 100
LL) is neither necessary nor recommended.

(Note: SOME mogas STCs do require using a higher octane car gas, but
those are the exception, not the rule.)
