With my ECU-tuned 100hp shxtbox (LOL~ why bother, right?), I can tell you that the subjective difference between a good day running Chevron 94 is pretty drastic compared to it running some Mobil / Esso 91 octane gas. My shxtbox just hates Mobil / Esso for some reason.
If I ever manage to own a 500hp car before 2035 - 2040, I'll tell you how big of a difference good gas vs crap gas feels LOL~

I trust Grassroots Motorsports because they do things methodically and measures stuff objectively. In one issue a couple of years ago, they tested a fuel additive and found some
measurable gains from using it. I can't remember whether they ran the test on a dyno, or whether it was timed against the clock. They ran the same additive on a couple of different cars, and found (as the manufacturer has claimed) that the biggest power gains actually came from cars that runs 87 octane gas than those that run 91/93 octane gas. The GRM folks were very much suprised by the results themselves, but they weren't gonna argue against data.
Of course, I don't remember the name of the additive, nor can I find the issue where they ran this test. If anyone remembers which issue that was, I'd love to try it myself.
