Yeah, I take it that the Mirage has different engine settings for different fuel qualities in different regions of the world. It is a bit puzzling though. My owner's manual says the Mirage (Space Star) should drink min 91 RON. On the inside of my tank filler cap it says min 95 RON....

So, we may conclude that the Mitsubishi Space Star is faster/more powerful than the Mitsubishi Mirage!
