Diesel prices in France briefly undercut those in Luxembourg this Saturday, an unusual sight in a country known for pump tourism.
Luxembourg, despite its reputation for low taxes, applies national price caps on fuel. On April 4, the ceiling price for diesel jumped sharply to €2,186 per litre, pushing it above the rates offered at several stations just across the border.
France, by contrast, imposes no such cap. Stations are free to adjust prices as they see fit, and while diesel generally ranges from €2.19 to €2.28 around Thionville and Metz, Total stations remain an exception. Their temporary €2.09-per-liter cap, in effect until April 7, has made them the cheapest option in the area.
The bargain comes with the trade‑off of long queues. Drivers hoping to take advantage of the lower French prices should expect queues and slower service as word spreads of this rare switch.

On the other hand, the price gap for gasoline remains: a litre of SP95 sells for €1.758 in Luxembourg, while French gas stations sell it for around €1.95 to €1.99 per litre even at Total petrol stations.
