I was being an ass. Chevron is some of the worst gas in CA

93 octane is 93 octane. Octane rating is directly related to knock resistance. A possible explanation is the Costco fuel is actually higher than 93 octane. Is your log showing you’re making more HP with the Costco fuel? This would mean the CPU is allowing more advanced timing.
It was an awful attempt at a joke. Story of my life.Went right over my head.
FWIW, 3* of timing is not an “infinitesimal gain” in the least bit. That’s a LOT of extra power.I could care less about the infinitesimal gains given by 3 more degrees of timing on one cylinder due to better fuel. I am purely interested in getting my knock reduction as low as possible for the safety and longevity of my motor. And in my case the Costco gasoline produced less knock than the tank of 93 Shell gasoline that I had run earlier.

I know this has been debated in different places but having used supermarket diesel in my 2.0 GT I am sure that the brands, BP Shell and esso, give a bit higher mileage per gallon and the car runs smoother. What do others think?

Two of the most popular tuners for the mk7 platform, who are both in CA have found that Shell provides the best quality 91(I realize this is like saying one is the coldest person in Hell) in terms of knock reduction, and allowable timing. One of the tuners has stated that he has repeatably found that Shell 91 allows for up to 4* more timing than Chevron, specifically.I didn't know, why? I will switch to Shell. Merci.
What about cleaning additive? Techron is suppose to be one of the best.Two of the most popular tuners for the mk7 platform, who are both in CA have found that Shell provides the best quality 91(I realize this is like saying one is the coldest person in Hell) in terms of knock reduction, and allowable timing.
