Read this off another forum. They stated they contacted Shell, Esso, Petro Canada and another company (I can't remember the name). The official answer they got back was that there was NO ethanol in Esso or Shell premium fuels across Canada and Petro Canada contains up to 10% ethanol in ALL grades they sell. I just checked this out on PC's site and 94 definitely can contain up to 10% Ethanol.
