well im no expert but you cant deny that higher octane will result in more power. The kind we can readily buy may not be that noticeable, but think of this. When people dyno their cars and net lets say 200whp. Then for shits and giggles, they run it on high octane race fuel and net around 230 whp. It is a crazy jump, but its been shown in a bunch of articles. This is obviously a major octane jump, but it does show that 87 up to 93 would result in SOME power gain. BTW the new GTR is FACTORY tuned to run on......97 octane or some wierd crap , but somehow doesnt blow up with the 93 we have here. If higher octane had no benefit, legit "racers" wouldnt bother with it.
P.S however, beating the guy next to you isnt going to be determined by 87 or 93 in your stock/near stock yaris

I tried a couple of tanks of higher than recommended octane in my Echo a few years ago to see if my Scangauge could detect a difference in power or mpg,results were so insignificant that i never again wasted my money on higher octane again.
