Shell V-Power 91 Octane has been Ethanol free (in Canada) since it was introduced. Many US States require all gasoline to contain various percentages of Ethanol, so Shell was forced to add it to their V-Power in those States. So far Canada has no such requirements. Shell V-Power is the only premium gas without Ethanol as far as I know, so the Costco Premium and Ultramar Premium are probably re-branded Shell V-Power. Good to know!
