I live in California and in a rural part on top of that. Well I was happy to find a source for 100 octane fuel (and up) at a local performace shop.
Here is my question...I am going APS F.I. on my car ( already have my kit) and want to know what mix / ratio of 91 octane pump gas and 100 octane fuel I should run. I want to have 94 octane gas as a safey margin on my APS TT Z. How many gallons does our gas tank hold and what should be my ratio ( 100 octane / 91 octane = 94 octane ) ???

Thanks

Appreciate it Sharif...that helps alot. I think I'm going to buy my 100 octane in a 55 gallon drum and keep it in my garage. That should make it a little less burtal on the wallet
Can people chime in who are in California and tell me what you pay for 100 octane! Thanks for any respones
Now I should be set for a higher boost map on my Unichip even in California. When Unichip comes out with the toggle switch then I will be able to take my car on road trips and switch maps to suit only 91 octane crap cali pump gas!

 

San Jose-


Almaden & Foxworthy 4.39 gal

I usually mix 4gal 100oct and then 91. Im usually out 30 bucks if I fillup with just about 1/4 tank left. Not bad...

 

$4.99 gallon for cool blueee 100 octane ..southern Cali

Many thanks fellows....what I priced for 100 octane at my local performace shop was a rip off (which does not surprise me). I live an hour north of Sacramento ( largest town: Chico = 100,000 because of Chio State University) and we really don't have a tuner scene up here ....that is until I get my kit installed!
