leaded fuel FTW

 

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?

 

Incorrect, the AKI for California fuels is 91 octane, we just have a different blend with some additives. The knock index is the same and will function the same way with that regard (I don't know who thought that CAL91 == Others89), all this stuff is carefully monitored by the state to make sure we don't get shammed by gas pump owners.

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?

 

Petitions, especially the online ones rarely do anything but give people some happy go lucky feeling that they were one of the many that signed up for it. How many online petitions have you actually seen do anything?

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.

 

says your 02 sensors and cat

 

Yeah FWIW 93 in NY was cheaper than 91 here.
lol who runs cats?
