Double check with teh gas companies - but in Ontario Shell V Power gold is the only one with no ethanol. Sunoco/ Husky / Petro Can 94 does have some ethanol - nit so good for cars that see limited use or sit in storage as it can attract moisture. Really do not believe you will see a difference in running 91 vs 94 octance - as it is up to so many setting on the cars computers to adjust how it runs on the fuel. Manual and Nissan call for 91 so use that - ideally Shell.
