bcowanwheels says:
"airplanes are hi-compression and run very hi octane fuel plus there tuned to run with exhaust that way. there like a race engine with open headers."
Then Mean buzzen half dozen A.K.A. Hank says:
"Airplane engines in general are low compression air-cooled engines."
Now it is obvious even to my limited intellect, that you cannot both be right.
I am more confused than ever. Perhaps it is time for me to give Google a workout and see what HE says.

Just wondering what google has said?
I am an A&P mechanic, I have worked on the smaller air cooled low performance engines in school & my first job was fueling airplanes, then later was working on them, so I know first hand.
I started working on aircraft in 1988,even then, there was only 100 low lead fuel available , never seen 130 octane even available to this day.
A Cessna 150 has a Continental 0-200, 200 cubic inch air cooled opposed 4 cylinder engine, nothing high performance with that engine.
The cylinder head design is horrendous, the exhaust looks just as bad.
That is just one example, there are plenty more.
