Aw really? Shame. By law here, they have to mark which gas types have ethanol and what % (with a big bright green sticker).

The cold would really mess up a high compression engine as ethanol freezes at -17 C (1.4 F) and releases water molecules in the gasoline. And you really, really don't want that going into your turbo'd engine. Given that is the average winter temperature here...well you can see where I'm going with this.

Come to think of it, I don't think I have ever seen a supreme gas (our highest grade) with ethanol around my parts.
