91 octane is 91 octane is the same regardless of the blend...really? Winter blend gasoline is way different chemically speaking than summer gas...and yes winter gas boils at a lower temperature to aid with cold starting, etc...this means the gasoline is more volatile, even though the additives in the winter blend raise octane ratings...there are many factors in how and when gasoline detonates...and according to my knock counter, I am knocking now, and never did in the summer...changed to Randy's 91 tune running 93 octane, no more knocks...can't argue with data, but post another lame panda picture just to make yourself feel better
Yes, it is 91 octane regardless of blend. If it was say, 89 octane, then it would go into the tank that dispenses 89 octane.
I never said you weren't knocking, but that is just as much a factor of the tune than it is the octane. You said yourself that you switched to the Cobb OTS tune and had no more knock, which would lead most reasonable people to believe that it was your tune
, not your fuel. You now go on to say that with your 91 tune you are no longer getting knock when running 93
octane. Just read that and think about it a little...
You've proven yourself in many different threads to not know what you're talking about and/or come to the wrong conclusion based on the information you've given. Hell, maybe you're just trying to troll again. It's not a huge deal. If anything it's what many people have come to expect when seeing you bump a dead thread with gibberish.
Per your request, another panda picture:
