BMW's recommendation, in the US, is for Top Tier gasoline. If you check your owner's manual, it likely says the same in Canada. Top Tier gas stations in Canada are:

Chevron Canada
Esso
PetroCanada
Shell Canada
Sunoco Canada



For those of us in the US, Top Tier brands include many that I have never heard of. The current list is:

76 Stations
Aloha Petroleum
Chevron
Conoco
CountryMark
Entec Stations
Exxon
Holiday Stationstores, Inc.
Kwik Trip / Kwik Star
MFA Oil Co.
Mileage Stations
Mobil
Phillips 66
Quik Trip
Rebel Oil
Road Ranger
Severson Oil
Shell
Texaco
The Somerset Refinery, Inc.
Tri-Par Oil Co.
U.S. Oil

I refuel at Exxon/Mobil and Shell stations. I wish that Sunoco US were a TopTier participant, as I would get a small discount from a friend who owns a Sunoco station.
