Yeh, I have heard before that the high octane is not blended but then I read on the Internet somewhere that the laws are getting written that everything must be blended.
I don't know. I know they are not labeling it though.
High Octane, called "premium unleaded" at most places in Iowa can be either blended or not .... depending on the outlet. I've even seen a few stations that handle 100 octane unleaded racing gasoline, most of this is a 10% blend. Mostly used by the street rodders. Again, always labeled here. I tried some of this stuff in gassers and it seems to run OK but sure smells better than regular gas. But at almost twice the price, I'll stick with the 87 or 89 octane stuff.
