you can run 87 fine, but if you have your car custom programed like some people then you have to run premium

I ran 87 for the first 6 months I owned it and it started to act really bad, ruff idle and other stuff. As soon as i went to premium, all my problems stopped.

The Way I Understand It Is You Can Run 87 And If Its Rough Or You Hear Knocking You Got To Use Premium
