Currently Waze only allows four different fuel types for fuel stations. I believe that number is not enough. For example in Finland we currently have 95E10, 98E5, Diesel and E85 as options in Waze. In reality many fuel stations offer renewable/green diesel, natural or bio-gas and some even have AdBlue (DEF) from a pump. Currently around half of my countries fuel types can not have prices set for in Waze.

So, my suggestion is that community members should be able to add a price to any fuel type available at a given station, wich would require an increase to the amount of fuel types a country can have.

Also, you should be able to pick in the editor wich types are available at wich station, so you wouldn't have empty slots at those stations that don't offer all of the options.
