You just used a whole bunch of big words to say its octane rating is higher and, with a motor properly set up for the application, you can increase compression/boost safely without fear of detonating. Im not saying you're wrong and it IS good info...just already stated is all.

Or maybe you misunderstood me saying, "Seriously?" - I meant it in the MOST sarcastic way haha

Yes, I meant it just confirming your opinion but a little bit different with some numbers.

It is forbidden for BWA engines for example - you know them as original 2.0TFSI (also like 2.0TSI in later VW) and 200HP. It is because most of components are not resistive to corrosion process caused from bioethanol. Fuel pumps are failing in 2 year warranty in these engines. But my TT with that engine had 80 kms and 4 years, when I sold it with no issues except fuel pump and ignition coils. Actually this engine is used in many popular cars in Europe Octavia RS and these cars can do 500 kms with that engine.
But in these years it was just 5% of bioethanol. 10% is new and defined by law (you couldn't buy pure gasoline). In US is also added 5% at least to Gas.

And plus side - bioethanol is natural cleaner for engine and more efficient/aggressive than additives, so can clean carbonization, which is common problem to all TFSI and FSI engine even after 4000 kms. So in older engine you can observe bigger consumption of OIL not caused by corrosion, but by cleaner engine.
