In France (and maybe other countries) gas station propose various type of SP95, you have regular SP95 and SP95-E10. SP95-E10 is cheaper than SP95. Generaly expensive gas station propose SP95-E10 to appears less expensive than supermarket. And some gas station propose both SP95 and SP95-E10.
In Waze if I am correct you have only SP95, SP98, Gazole and GPL as possible fuel.
It maybe intersting to be able to define the available fuel inside the map editor, up to 4 or 5. With this it will become possible to differentiate SP95 and SP95-E10 since they are not the same fuel !
