Luxembourg–Longwy: is the fuel stop worth it?
Drivers on the Luxembourg to Longwy route should compare the current Luxembourg border fuel price, the real detour and the number of litres before leaving the normal road. The stop only works when the cheaper station stays close to the route and the fill volume is large enough.
Decision question
Is the cheaper fuel stop on Luxembourg to Longwy still worth it after the detour?
What Kilomo should compare
- Live price gap between the route countries for E10 / Diesel, not a stale national average.
- Real detour from the Luxembourg to Longwy route, including the extra distance back to the main road.
- Tank size and likely waiting time, because small top-ups rarely justify a border detour.
Luxembourg to Longwy: fill up before entering France?
If you drive from Luxembourg toward Longwy, filling up before crossing into France is often a sensible choice. Luxembourg fuel prices are nationally capped and are often below French prices.
The decision still depends on your actual route, how much fuel you need and whether the stop is already on the way.
Why filling up before France can work
A Luxembourg station near your exit route can preserve most of the price advantage because it adds little distance. This is especially useful for commuters and drivers returning to the Longwy area.
Example calculation
With a 50 L fill and a 10 c/L Luxembourg advantage, the gross saving is €5. If the station adds only 0–2 km, most of that saving remains.
For a 15 L top-up, the same gap is only €1.50. In that case convenience may matter more than price.
When to wait for France
- You only need a small top-up.
- The Luxembourg station requires a detour.
- There is a long queue.
- You are short on time.
- You have a fuel card that only works in France.
