Shell is not planning on adding ethanol to its 91 octane gasoline.
All over Canada, Shell stations that have been converted to ethanol sites carry a maximum of 10% ethanol in Shell Bronze (regular 87 octane gasoline), and 5% in Shell Silver (mid-grade 89 octane gasoline). Shell V-Power (premium 91 octane gasoline) is ethanol free at all Shell gas stations (converted or not).
Thanks for the useful info. Isn't ESSO 91 octane same as Shell since they don't use ethanol in it and use it on 87 and 89?
