Premium Fuel?
I was curious if you really needed to run premium fuel in a Porsche. I know in my other cars the manufacture recommends it (Mercedes), but a lot of people, including some Mercedes techs, say it isn't necessary. That the computer will adjust the engine to what ever you put in it. The manufacture only recommends using premium fuel to meet their claimed HP and MPG ratings. I'm not sure I would run anything but premium in my Porsche even if they said it would be fine, why take the chance and I want all the HP I can get. I was just curious.
