In New Brunswick, most stations stock only regular and premium (2 tanks), the middle grades are mixed by the pumps to provide the desired octane.

We also have ethanol added to the regular and, by law, it can not be added to the premium. Therefore, the middle grades will always have a percentage of ethanol.
