Your analogy is not appropriate. Oil lubricates aren't meant to burn in the powerstroke of an 87 octane engine. Gasoline engineers build 87 octane gasoline engines to use 87 octane E0 gasoline. 87 octane E10 is two fuels, 114 octane ethanol & 84 octane gasoline. If a particular car, using(not burning efficiently) 87 octane E10 is knocking, it is the 84 octane gasoline component that knocks. Possibly, switching to 87 octane E0 could stop an 87 octane gasoline engine from knocking on inaccurate, but designated 87 octane E10. Also, 114 octane ethanol must ignite, mostly outside the powerstroke of the 87 octane gasoline. In essence, 87 octane E0 burns in the powerstroke of the 87 gasoline engine. That is why my last five featherfooted 87 octane gasoline engines got 8%, 8%, 7%-8%, 7% & 5% better MPG burning 87 octane E0, not using (burning inefficiently) incorrectly, but designated 87 octane E10.
Like you stated, octanes in gasoline are a mixture of molecules. However, 87 octane E0 is centered around 87 octane. Incorrectly, but designated 87 E10 has two centers, one centering around 84 octane gasoline component & one centering around 114 octane ethanol component.
