I have run 87 when not tuned and my mpg end up about the same. When tuned I need to run 93, big difference in the car with a tune, but I really cannot tell a difference using 93 without a tune.
Car is made to use either in stock form so run what ever you are happy with... probably boils down to $. Here in NC it is 0.60$ more per gallon or ~6$ a fill up or ~300$ a year, worth every penny with a tune! For me in stock form cannot tell a difference so 87 it is!
