[QUOTE=alcheng;2172986]Engine are design and tuned for certain spec/octane-value. For a normal OEM spec engine you won't get any difference between 91 or 94 since they are tuned for 91./QUOTE]

I disagree with this point.
The car will advance timing, and adjust per current conditions... (Like anything else, intakes, exhausts etc.)

Unless you tuned it and it requires 94, otherwise if the drivers manual says 91, 91 is as good as 94.

I tried both on the same car... no difference...
