Waste of time using higher octane than specified; more expensive, actually burns slower than motor designed for, no extra power.
Just use what the motor is set up for, IMHO.

or try any fuel additives to keep the lines clean?
Thanks

I personally avoid miracle additives in a bottle....Slick 50 never fixed (nor even made any noticeable difference) to my gearbox whine on my beater 30 years ago, so I've never trusted any since..
I think Chevron already uses Techron in all their grades, I tend to use their gas quite a lot.
The only advantage to the "premium" gas might be the additive package. I believe that some brands may put more cleaners in the "premium" package than the others.
I understand that there are now Federal standards for additives to gas; the advertising blurb on the pump says that Chevron already exceeded Federal standards with Techron when those standards were introduced, but the other gas suppliers had to up their additive pack to meet them - there were stories a few years about Chevron being trucked in to the motor city (where it's not available) for fuel economy and emissions testing because auto manufacturers got better test results with it.
Dunno, I was already happy with/using their gas...
But probably the best thing you can do for pretty much any Porsche, is using the gas up/the car regularly; take it for a good, long run as frequently as possible.
Every one I've ever owned or driven seemed to run way better around town for a week or so after running them for 4-6 hours (or ideally more) on a long trip.
That's probably even more important with ethanol-blended fuels; don't let that sit in the tank unused.
