I disagree but people can do what they want but octane ranges are not as bad as people think. Just consider many countries sell gasoline with vastly different octane ratios. You buy a Honda Accord in the US or Australia or Canada and the choice of fuel is quite different there is no standard for premium. There is a post of reddit where someone in Germany said regular is 95 octane and premium is 100 octane versus the US with regular 89 and premium 95. So there's a big discrepancy there how can the same cars in two different countries operate with such vast differences in octane?
