Do you have any info to back up the fact that this actually cleans out the system? Just wondering, because I've seen a lot to the contrary.

As to the original question, I've filled my tank up with 93, no difference whatsoever.

I actually don't, I'm just going by brand name (I did an experiment with Safeway vs Chevron with my GTI, but using 87 for both, and got horrendous FE with Safeway). But then, there are my Suby friends who swear against Chevron because it actually messed up their engines. Who knows, may be those "cleaning additives" in Chevron are bad for boxer engines?
