Gas matters?
I used to just fill up at Arco/Costco and call it a day. Now, I'm running Stage 2, and I've developed a bit of paranoia against knock of any kind, especially with our lovely local ACN gas. Is there a higher-quality gas station that you use (or ones to avoid)? Or is it all really the same?

I fill up on 76's 91 octane only from stations with one nozzle per grade. You would be surprised how much 87 octane you will get if that is what the last person used at stations with one nozzle for all grades. If I am stuck and can not find a station with one nozzle per grade I will get fuel from 76 or chevron and stay out of boost until I can put a gallon or two of 100 octane to cancel out any crap gas I got.

I too only go to stations with one nozzle per grade of gas. Maybe because I'm paranoid, but at the end of the day, i know i got straight up 91oct.
...Chevron ftw

I try to go to Chevron only, since they have nozzle-per-grade pumps. When i do go to Arco, it's when I'm going to Mexico. The one I pump at happens to have E-85, so I pump about a gallon or two of E-85 and the rest is 91. Have not experienced knock w/ this. Pay the extra 10-20 cents a gallon to avoid paying thousands on repairs.
