From October 12, 2018 in the 28 Member States of the European Union and the European Economic Area (Iceland, Lichtenstein, Norway) and in Serbia, Macedonia, Switzerland and Turkey, new labels and definitions for fuels are to be used obligatorily in service stations and on transport vehicles.
The new labeling, introduced by European measures, provides for the change of names also on the cap cover of the tanks. The obligation does not apply to the vehicles already in use, but now alongside the old definitions in all European countries there will be the same signal for all, with the aim of avoiding errors during the refueling phases.
The labels will have a different shape depending on the type of fuel: the symbol to indicate the petrol power supply is circular, marked with the letter "E"; the one for diesel is square with a "B" in the center; the gaseous fuels, on the other hand, are characterized by a rhombus. The code varies depending on whether it is hydrogen (H2), compressed natural gas (CNG) or liquefied natural gas (LNG) and liquefied petroleum gas (LPG).
In addition to the letters, some symbols will also present numbers: with the petrol E you will find the percentages of alcohol ethanol. E5 means 5% ethanol, 85% E85. So for gas oils: XTL is synthetic gas oil not derived from crude oil, instead the number alongside the letter B indicates the percentage of biodiesel.
The labels for power supply are under study while there are no indications for biomethane in cars and bioLNG in heavy transport.
