B7 — the label for diesel with up to 7% biofuel
A marking on the fuel pump under the European standard NP EN 16942: diesel with no more than 7% bio-additive (FAME) by volume. Until 1 October 2026 it was the only road diesel in Portugal. Since then it has stayed on sale as a fallback for vehicles not designed for 10%: suppliers are required to keep it on the market under paragraph 8 of Article 7 of Decreto-Lei n.º 89/2008.
Where you come across it. A framed label above the nozzle on the pump and by the car's fuel filler flap.
The duty to keep B7 on sale lies with the fuel supplier, not with every filling station: a particular station may not have it.
