x2. E85 is awesome. Closest pump to San Rafael is in Fairfield

The closest place to San Rafael would be Infineon but you'll have to mix the fuel to get around 93. I wouldn't recommend running your 93 map on a mix like this as it almost never turns out to be the same actual effective octane rating. Your best bet is to keep it on the safe side until you can get a tune for the 91 here.

It is easy to mix 93, or whatever octane you are after, as long as you put in the proper amount each time. Most modern gas pumps (read ALL of them) tell you exactly how much you are putting into your tank. If in doubt, use a touch more to err on the safe side. |
Does everyone believe that our 91 pump is always 91 octane? I would think we know better than that by now. It is also worth considering that Cali 91 is not the same as other states 91, as there are additives used. Rumor has it that our 91 is more like 89 from other states, but I have not personally read any documentation on the truth of this. Tuners?
Granted, it is best to have a tune for whatever gas you are getting from the pump, especially for a daily driven tune...but how many people out there are running 100 octane tunes that are tuned on 104 octane mixed with 91? I can think of quite a few, and the PPB forums will show you quite a few more. I have always found this to be a questionable way to go, especially for a race gas tune.
E85 would be great, but it is not available everywhere. Additionally, the fuel system upgrades are not in everyone's budget.

And surely you're gonna pay for my 1000 cc injectors and dyno day? Oh and come fill up my car personally every time I need gas so I don't have to drive 50 miles out of the way for it? (Even further than for 93) 
I guess I'll head to infineon some weekend for it. Quick question though, do we know if that site is correct? For some reason I thought mixing fuels to get the desired octane is a little more complicated. For example 5 gallons of 95 and 5 of gallons of 105 doesn't just make 10 gallons of 100 like the calculator would suggest. Does it?

BTW: As far as I remember, we lost the higher octane stuff in Cali not due to CARB, but actually because an oil company was stupid and sued itself or something like that.

What would it take to start a petition to get California gas at the pumps brought back up to 93 octane or maybe have them offer Premium still as 91, but then a Super Octane or Ultra Octane at 93/94?

Again, this isn't an issue with California not allowing it, it's due to patents and royalties with the way the fuel is blended to make 92/93 in this state. This is a legal issue due to greed from a refining company.
If someone wanted to go with a higher octane they can blend it themselves with a 100+ octane pump, go with meth injection, or just convert to E85. $0.02

Yeah, I've already done the blends myself. Our "Premium" Octane is more expensive then most other states. That means we are not only paying more for our gas, but we are getting double screwed by having a lower grade to begin with.
I'm sure there is a legal way to bring the octane ratings back up in California, just got to figure out what it would take in order for it to be done.
