there's a 76 station when the 110 ends in pasadena that used to sell 93 octane. but this was a few years ago. also priced at like $11/gallon.

I've filled up there once (caravan-ed with a guy on race).. Don't think it does anything without a proper tune. But cool shop, and dead.

Octane boosting additives are junk. I don't care what they want to show in the video, the fact is, if you understand hydrocarbon chemistry, you can figure out for yourself why something in a tiny bottle can't possibly increase the octane even a single point. Add to this the only thing that matters - do you have sufficient octane to prevent ignition retard induced by knock sensors? If you do, then no octane increase will change the output positively. It is possible to lose power using extreme octane rated fuels because the octane enhancers have less BTU per gram than lesser fuels.

I agree, Cali fuel sucks rocks, especially in my Supra - I get 12 mpg driving around town with 91 octane and 18 mpg around town with 93 octane. But the 2UR-GSE was designed and built to run cleanly, efficiently, and powerfully on Cali 91 fuel. There is no point in going to any fuel extremes looking for more power unless you are boosting or squeezing. Period.

funny how the highest octane is supreme but the mid octane is ultra supreme

Bringing up an old topic but I usually pump 91 Costco gas here in Socal but it seems like everytime I use Shell (when Costco lines are too long) my IS-F seems to drive so much better. Anyone else pump Costco or have any feedback on their gas?

I've been blending 91/e85 4:1 for the past 2000miles while living in socal. I Haven't had any issues with it. The power delivery feels a bit smother, I feel I may be running more timing but I have no ways to check.

Been doing the same. Power delivery feels smoother, and the engine also feels like it is running way smoother. Almost feels like a different car.
I highly recommend mixing e85 with ****ty California 91 oct.

^^ This is what i have been doing. It's rather an old thread as I was the op but since then, with the rr-racing tune, 91 mix with e85 has yielded my KCLV to 23.9. Before I was at 21.1 with just 91 octane.

yeah they top out at 91 here in vegas as well, but some gas stations you can find 100oct. but you have to look high and low

+1, some minor difference in the way the car runs, but not a big difference. (Another Ex-Californian here)
