supreme does NOTHING in the micra besides lighten your wallet faster....The comments on "crap gas" are people who have no knowledge of gasoline and its workings. USE REGULAR.
In the micra, Regular gas makes more power, burns hotter, cleaner and gets you the best milage you will get from it. If anyone says otherwise, they are 1. uninformed or 2. Lying.
