Default California Gas Alternative?

I live in California where the highest octane pump gas is 91 octane. I was wondering what alternatives there are to using store baught octane boosters from Kragen. I live right near Sears Point/Infineon Raceway, do they sell race gas? I heard so one talking about buying drums of chemicles from Sherwin Williams and mixing it up. Can anyone shed some light on this subject?

You can go to the Unocal76 web site, and search for a station that has 100 octane "race" fuel. I have ~2 76 stations near me in Los Angeles that carry it.

There is supposed to be a 76 station with 100 octane in Fairfield. http://www.76.com has a station finder which will tell you were to find 100 octane.

The guys going to the Sherwin Williams or other paint depot are buying drums of Xylene or Toluene, which is an effective octane booster.

Do a search on octane and Xylene or Toluene and you'll come up with a lot of info, even on this forum.

Default Will it run on 91 octane or not????

I live in Calif and really really want an STI, will the cars ECU allow the car to run on 91 Octane or not? The owners manual on page entitled Gas Station Reference say the car requires 94 octane and can run temporarily on 91 octane. SOA in a reply to my email inquiry said the octane rating only effects horsepower and the car will run perfectly on 91 octane. They also do not recommend the use of octane boosters. Race fuel is $5/gal-about $75 for a tankful (not economically feasible; in my opinion handling Toluene or Xylene presents unacceptable health risks.

1. Mix in unleaded race gas.

2. Toluene

(both as mentioned above)

3. Water+Methanol injection and proper tuning....

You don't strictly need to do any of this. I drove a friend's STi this weekend in 115 degree heat in Tucson, AZ with 91 octane gas. He just got it back from the dealer with the ECU flash a few days before. No pinging. And I took it to a deserted twisty road and drove it for real. Mind you it wasn't my car and I couldn't believe he let my wife and I drive it at all, much less without him in it. I took it a bit easy, but not that easy


If the thing was going to ping, it would have in that heat, being driven in a "spirited" fashion.

Maybe it lost some power compared to running 93+ octane fuel, but it still had plenty left.

Ok it took me hours of searching online and a trip to Sears Point/ Infineon Race way but I got some great information. The raceways gas station carries 104 OCTANE!!! But the price was more than $7 a gallon. They have cheaper fuels as well, 93, 95....etc. I also went in to a local paint store and found Toulene, the guy there was very noligable about its octane boosting capabilities. He told me to ad 1 gallon of Toulene to every 4 gallons of 91 octane gas to get ~ 94 - 95 octane. Can anyone verify this? Thanks for all the help and replies.

Have you tried just plain ol Unocal 76 91 octane gas? Its much better than everyone elses 91 gas right now, as they are the only ones using an ethanol based gas. I noticed a difference when I switched to 76 gas.
