IIRC the only E0 gasoline commercially available in my country is AvGas, yet its lead content renders it unsuitable for any car with its catalyst still in place. And it's so expensive that most of the piston-engined cropduster aircraft here fly on ethanol, which BTW is not so cost-effective for the flexfuel cars. Even though in some regions it's quite common to use regular E5 or E10 pump gas smuggled from neighboring countries instead of AvGas, it's an illegal practice here.
