These labels will be placed on the nozzles of all filling pumps, on the pumps themselves and in the immediate proximity of the fuel filler flap or cap of cars. The new labels are divided into three groups, with an identifying shape for each type of fuel: gasoline will be marked with an E inside a circle, diesel with a B inside a square, and gaseous fuels will be marked with a rhombus. The new law aims to help consumers select the appropriate fuel for their vehicles.
