I found Shell to give the most ST Knock Retard and BP to give the least so I stick with BP for now. Also if I mix in Sunoco 100 to give 95 octane I get no Knock Retard.

So long as you use Top-Tier gas, your car will be well fed. To learn about Top-Tier gas go here: Top Tier Gasoline

I personally use Shell. Their 91 octane pump fuel contains the most detergents (V*Power) of any gas sold in the US. I also use it because I'm a huge Ferrari Formula 1 fan, and Shell produces all the fuel and lubricants for the team. The F1 technology allegedly trickles down to their consumer products.

Seem to have best results with Chevron 91 (no 93 at 5K above sea level)

I use the least expensive regardless of brand and have never had a problem. Ditto with my Viper.

1. Sunoco
2. Shell or BP

Those are my top gas lines... My sunoco has 91 and 93 available, but Shell and BP only have 93.

Interesting. Do you know this by logging for ST KNK with the tuner or are you going by not hearing any knock?
