Getting rid of the heat is apparently not the reason plane engines need more oil.
After all, gas guys easily get away with just 2-3%, or even less.
Thats a strange thing to say since gasoline has no lubricating properties as such, its more that gas engines tend to be larger in size and so can physically support needle rollers on the big and small ends thereby eliminating the most critical oil dependant sliding part of the engine. And the finning on these engines seems to be proportionally much larger in area than its smaller glow cousins.
