My view, having owned a few turbo-charged petrols over the years is that a higher octane rating fuel will give you a greater resistance to engine knock or premature detonation when comparing the use with a fuel with a lower octane rating , quite apart from the fact that the engine or cylinder knock sensor, will retard the ignition (in response to engine knock) thereby robbing you of the efficiency you would of obtained, had the engine NOT retarded the ignition. My opinion of that is that if you run on fuel with reduced octane rating then the engine is running with retarded ignition as in my handbook it recommends useage of " High Quality Fuel" 95 minimum. Its only about a fiver a fill up dearer and in my opinion is worth it for peace of mind as you can search the web for pictures of pistons with holes in them from detonation and they are not all from racing engines.
