Here, non-oxygenated (no ethanol) premium is available at only a very few stations and it's technically illegal to use it in anything other than boats, off-highway vehicles, or collector cars. I have a 250 gallon tank that I use for boats and have it filled with the non-oxygenated premium a couple of times a year but I see no reason whatsoever to bother with ethanol-free gasoline for any of my cars, Z included.
