You got 9% better gas mileage. Premium didn't cost you 9% more. So it IS worth it if these numbers are consistently what you get.
Some cars/trucks DO get better mileage on premium; especially turbo'd engines. Our Audi gets enough better to pay for the premium and it performs better. Our VW 1.8 Turbo gets 10% better on premium than regular and performs WAY better. I also run premium in our F150 Ecoboost (twin turbos) and my experience is that it pays for itself also. BUT, MOST vehicles will not give you a return on premium unless they are specifically designed for it.
So, bottom line is, you can't make blanket statements about this issue. It depends on the vehicle.
