Performance will not be optimum but miles per gallon shouldn't be much different.
Anybody agree?

I agree to a point. I think in a lower compression engine, that would hold true. But in a higher compression engine, the ECU will retard the timing to compensate for detonation and you will get less power each stroke.
I was asleep the semester we had that discussion in college so I will yield the floor to someone who paid attention.
