Where is the best gas?

I've heard Mobil, but could be wrong. Reason be that my SpecV has mad hydrocarbon ping at the end of a trip. I found that Citgo's 93 seems to do the best, but am wondering if better is out there.

We have:
Citgo
BP
KwikTrip
Fleet Farm Gas
Mobil
Baltus
Weiler's
Walmart Gas
and probably others...

Do not. >>

I've heard its better to switch it up. each brand has different additives so if you use all of them its the most beneficial for your engine
