Remember...your Porsche wants 93 octane. Mix a few gallons of 100 in there to bring the min up if you're going to run it hard.

Race Gas in Los Angeles and Southern California

 

Have you guys ever heard of the SERA racing additives? I have been using them for about a year now in my 997TT and they make a hell of a difference! I will post pics so you can see what I mean. I use a 10% infusion as an octane boost and I get improved power, throttle response and sound.

 

Theres one down the Street from my House Been going there for almost 5 Years for their 100 Octane Goodness.

That Map is missing one Station across the street from my Office as well - Crap Gas Station (USA I believe??) But they have Trick Racing Fuel!

Vanowen and Desoto in Canoga Park.

 

Infineon Raceway, which is less than 10 miles from my house has a Sunoco station onsite with 91, 96 & 100 unleaded and 112, 114 and 116 leaded.

If I only owned something worthy of the high-octane stuff.......

 

96 Would be nice to have around - I used to mix 100 & 91 to try and save a few bucks...

 

93 would be nice to have around, you know like they have in the rest of the country

You get the most power from the lowest octane you can run that doesn't ping, so I run a mix of about 3:1 91:100 to bring it up just over 93. Runs great on that mix, I definitely feel power coming on early. The motor will run cooler in hot temps too, not that that's been a problem but I know turbo peeps have issue with heat soak sometimes.
