First the bad news, tax increases in Luxembourg have closed the gap between France and Luxembourg. Apparently the French, Belgium and German Governments were complaining about how many of their citizens popped across the border to fill up in Luxembourg.
However prices remain amongst the cheapest in Europe.
Fuel is much cheaper in Luxembourg – we paid 1.24 euro (£1.097) a litre for diesel today, in Dover it costs £1.429 a litre. In other words fuel in Luxembourg is 23% cheaper than in the U.K. In Calais it is 15% cheaper than the U.K.
