I have done 5 drag weeks so my car has had about every brand of pump gas run through it at some point. Any ET variance I have had between tracks has usually been a result of the weather. My combo doesn't seem to care, 91, 93, Ethanol or No Ethanol it runs the same.

My best timeslips (9.5s at 140 mph) on pump gas were using no name 93 pump premium from Sparky's fireworks...store right up the road from my house, lol. Runs just as good on that as it does w/ any other brand in it. I really don't think it matters.

I have been using Sunoco Ultra 93 and Marathon 93. I my area they are the two brands that have the least amount of alcohol. I have not seen any difference in e.t. between the two.

A couple (few?) decades back, David Vizard did a lot of research on different brands of pump fuel looking to see if there were any differences worth knowing. He did publish some interesting stuff (e.g., some fuels ran better w/ cooled induction systems while others lost less power when the induction was heated) on it. However, it's so out of date that I'd question if anything he found during that effort still applies.
The other thing I can only wonder about, since I'm not in that industry, is if there are more govt. restrictions that reduce the variances in how different oil companies blend their fuels for modern cars. If there is any truth to that, then that fits in w/ some peoples' experiences that brand didn't make a difference.
FWIW, I tried to stay w/ Sunoco and Shell when possible, if only because they both still offer 93 in my area and they're two of the closet stations to my home.

Depends on if you are optimizing the time for each fuel. While most pump fuel will likely be similar, there is a difference between E0 and E10. Besides the stoich AFR being different, I have seen some knock benefit from the E10 in Dyno testing. Gained 1-2 degrees spark before detonation. This is huge on a high specific power turbo engine.
