How have I been negative? My point was that there’s nothing to choose from between anything rated as SUL, which from any way you look at it is proven by the results as we’re talking single digit percentage points across one test, hardly conclusive that any fuel is better than another. Yes it’s interesting, but nothing more. Certainly there’s nothing in there to make anyone drive out of their way to buy anything other than whichever one is closest/cheapest, even if they were going for ultimate power. Way too many variables to still consider.
Carry the same test out on multiple cars, taking fuel from various locations at varying levels on freshness, across multiple dynos (including engine ones) and I’d be happy to change my viewpoint.
It’s not about being negative, it’s about being reasonable and open minded. You appear to have latched onto one thing and believe that as gospel regardless. I’m saying look at it a bit deeper than a headline, and you’ll learn a lot more.
