I always ran the StreetBlaze 103 ( the streetblaze name is new...) as pure as possible. If you follow the descriptions on there you should be fine. I don't see why you would need higher octane on a NA car though....

76 used to have a great link on their site showing exactly how to mix and match and what the numbers are but it's no longer there...I was told a while back that they no longer produce 100 octane which I guess is not quite true since there are still some gas stations selling it, but they no longer advertise it.

 

If your Z is mostly stock (no exhaust/intake/headers/plenum, etc), 100 octane is a waste of money. You won't get any noticable increase in performance. Higher octane is only worth it if the car is F/I.

 

Im sure thier are a lot of FI people in socal who would like to know where to get some 100...

Once we get all the sites together we can make a FAQ with this...

 

excellent idea, 7.

 

I went to the 76 station off of LaPaz and filled up with 100 octane. I was on empty when I filled up. On my trip back home I couldn't feel a performance difference in my N/A Z. The engine did sound meaner but that easily could have been due to me pushing the car harder than I normally would. I only went through an 1/10 of a tank so maybe the ECU would take more time to adjust? Either way I was not expecting big gains. I just mainly wanted to see what the difference, if any, would be.

At nearly $6 a gallon, it get's expensive very quickly and isn't worth it for a N/A Z.

I have a 2004.5, btw.

 

ya, but if you have a lot of breathing mods, the lower octane gas will cause knocking. higher octane will eliminate this and make things run smoother.

 

I have a few breathing mods on my Z. Still didn't notice a difference. I'll take it out for a spin later tonight and see if I notice anything.

 

I believe that the place in Yorba Linda (Yorba Linda Blvd./Imperial Hwy) closed.

There is a station on Commonwealth in Fullerton that has racing fuel, however.

 

Also I don't know if this is the same on the Z but in order for the ECU to recognize the higher octane fuel on my celi I needed to reset the ecu after filling up with 103 octane. Food for thought...

 

place in san diego sells it as far as i know. off of the 8 in el cajon i think off of mollison. maybe magnolia. its right off the freeway and they sell race gas, big yellow sign. hope that helps.

 

Here is what we got so far.

Stations:
* 76 Station off of LaPaz and the 5.
* 76 in Pasadena has em Corner of E. Glenarm St. and Arroyo/110
* In chino off of edison and central
* in yorba linda off the 91 and Imperial (May not exist)
* Off the 60 exit Phillips Ranch Rd North, At Villiage Loop go right and its the 76 Station on the left side.
* on Commonwealth in Fullerton
* off of the 8 in el cajon i think off of mollison. maybe magnolia; right off the freeway and they sell race gas, big yellow sign.

thanx for the sd info!

 

Are you kidding me?!?!
That is where I litterally live.

You're telling me I didn't know about this for 15+ years?

 

now we know where you live!

 

Here's a guess:

[(16gal x 91oct) + (4gal x 100oct)]/20 = 92.8 octane

 

we have a 20 gallon tank ! wtf my gas gauge lies to me ive never put more then 18

 

Yeah that seems odd to me too, i've never filled over 18 either and I've driven close to 100 miles on the empty dashes before.

 

at least next time i get the dashes i wont panic

 

Stalkers.


I stopped by after work today and sure enough ... race gas' sold at that station. OMG!!! How sweet is that!

I've managed to pump in ~19.2 gallons once. I ran way passed the 'yellow' light because I had no choice. I wouldn't recommend trying doing so, but there was no gas station around. Did my best feathering the throttle in order to maximize fuel efficiency. Another dude on the G35 Driver forum managed to reach just over 500 mile w. a single fill up. It took 19.8 gallons to fill his tank! Yikes!!!

 

i drove from concord CA to my house on one tank, it was high 400s i believe, it was fun too avg speed 76 mph
