I read an article in Excellence magazine that you should use swepco fuel additive to get more performance out of you porsche engine. Just wondering if any one uses any type of fuel additive and if so what kind?

I've been using Stabil lately with the ethanol enriched fuel we have now. It should prevent moisture buildup in the tank. I use SeaFoam in all my cars to remove carbon.

I consult with a fuel company named Sports Racing Fuel, they have the ONLY additive that in my opinion works. Its called SURA, it is unleaded 118 race fuel, when mixed with 91 can achieve a 103 MOTOR octane. I sell 5 gallons for 75 dollars and that will mix 10 gallons (15 overall) of 103 (20 gallons overall) of 100 and (25 gallons overall) for 98 octane. you can find out more at sportsracingfuel.com

15 bucks a gallon?!?!?!?
What kind of compression are you running to require such high octane? Not to mention if this is mixed with E85 which already has a high octane rating.

Be curious to see what the Dyno numbers are for you motor running on that gas blend.
