The owner's manual recommends at-least 87 be used, this is not saying that it is the best. 85 can be used in higher altitude, also according to the owner's manual. I've tested mine on a lot of interstate driving and found 89 gave me the best mpg and performance, but I still mix in a tank of premium randomly. This is just habit.
