All Ultramar service stations sell 87 Octane fuel, which contains up to 10% ethanol, except in Prince Edward Island, Newfoundland and the Quebec City region, where 87 Octane fuel is still ethanol-free. For 91 Octane fuel, all regions have up to 10% ethanol content except for the Provinces of Quebec, Prince Edward Island, Newfoundland, and New Brunswick, where 91 Octane fuel is still ethanol-free. We indicate on the pump or by the grade selectors if the gasoline does not contain ethanol or contains up to 10% ethanol.
