Luxembourg fuel prices today — petrol & diesel comparison
Luxembourg caps fuel prices by law — typically 10–20 c/L below German prices and 15–25 c/L below French prices. Learn how the price cap works, see the current gap, and find out from which border town the detour pays off.
Decision question
Is a fuel stop in Luxembourg worth it at today's prices — and from which direction?
What Kilomo should compare
- Luxembourg sets weekly national maximum prices by ministerial decree (prix maxima) — historically 10–20 c/L below the German market average.
- 50 L of diesel at a 12 c/L saving: €6 net per fill. Twice a week on a commute: over €600 a year.
- The break-even detour is roughly 3–5 km for a 50-litre fill. Beyond that, the detour itself burns more fuel than you save.
- German motorway prices are an additional 15–25 c/L above the Luxembourg cap — drivers passing the A1/A64 corridor save the most.
Luxembourg is the cheapest place to fill up in Western Europe — not because stations run promotions, but because the government sets a weekly maximum price for every litre sold. For commuters crossing the border from Germany, France or Belgium, this price cap is a fixed line item in the household budget.
Why fuel is cheaper in Luxembourg
The Luxembourg government fixes national maximum retail prices (prix maxima) for petrol and diesel via ministerial decree. These are typically adjusted weekly, taking into account international crude oil prices, exchange rates and tax rates.
The main driver of the price gap is significantly lower excise duties (accises). Germany adds a CO2 levy that Luxembourg does not have. France and Belgium also apply higher energy taxes. The result: the same litre of E10 or diesel regularly costs 10–20 cents less at Luxembourg pumps.
How big is the price gap today?
Exact prices change with every cap adjustment. Rather than quoting a figure that will be stale tomorrow, check the live comparison on the Kilomo homepage — prices from all four border countries are updated daily.
As a guideline: in 2024–2025, the typical saving was 10–20 c/L versus Germany, 15–25 c/L versus France and 8–15 c/L versus Belgium. German motorway stations are even pricier — the gap to the Luxembourg cap often reaches 20–30 c/L.
| Neighbour | Typical saving (E10) | Typical saving (Diesel) |
|---|---|---|
| Germany (market price) | 10–20 c/L | 8–15 c/L |
| Germany (motorway) | 20–30 c/L | 15–25 c/L |
| France | 15–25 c/L | 10–20 c/L |
| Belgium | 8–15 c/L | 5–12 c/L |

What does that mean per tank?
On a typical 50-litre fill at a 12 c/L price gap, you save €6 per stop. Sounds modest — but it adds up fast:
| Frequency | Monthly saving | Annual saving |
|---|---|---|
| Once a week | ~€26 | ~€312 |
| Twice a week (commuter) | ~€52 | ~€624 |
| Once a month (occasional) | ~€6 | ~€72 |
From which town does it pay off?
The net saving depends not just on the price per litre but on how far you detour from your usual route. The shorter the detour, the more you keep. Key border towns:
- From Trier: Only 15 km to the first Luxembourg station. Commuters on the A64/B51 practically drive past it — maximum saving with minimal detour.
- From Saarbrücken: About 100 km to Luxembourg City, but the first Luxembourg stations on the A620/A8 appear after 60–70 km. Best for commuters already heading that way.
- From Metz: 55 km via the A31. For frontaliers heading to Luxembourg, the fuel stop is part of the daily commute.
- From Arlon: Right at the border, under 20 km to Luxembourg stations. Smallest possible detour.
Kilomo has a dedicated route page for each of these corridors with live price comparison, detour time and net savings — use the route planner on the homepage to check your specific journey.
When is it not worth it?
- When the detour exceeds 8–10 km and you only fill 20–30 litres: the extra fuel burned on the detour eats into the saving.
- On Saturdays and before public holidays: Luxembourg border stations are packed — 15 minutes of queuing can wipe out the time benefit.
- When the price cap has just risen and the gap drops below 5 c/L: rare, but worth checking.
Frequently asked questions
Does the price cap apply to all fuel types? Yes. Luxembourg sets maximum prices for E10, E5, diesel (B7) and other grades. The saving varies by fuel — the diesel gap with Germany tends to be slightly smaller than for E10.
How often does the Luxembourg price change? Typically weekly, by ministerial decree. Large crude oil swings can trigger more frequent adjustments.
Can I check the current price online? Yes — the Kilomo homepage shows daily-updated prices from all four border countries. Enter your route and the planner calculates the net saving after detour costs automatically.
