Petrol prices in Luxembourg and the state's maximum

If you’re driving in Luxembourg, there’s something worth knowing that you won’t find at home. The price of petrol and diesel has an official ceiling per litre, published by STATEC, the national statistics office, and it changes several times a month. Filling stations can charge less, but never more.

The cap as of September 2026

According to STATEC’s series, the maximum price of 95 unleaded has been €1.835 a litre since 24 September 2026, and diesel €2.095 a litre since 25 September. Those were the figures in force on the day I’m writing, 29 September, and I wouldn’t rely on them for more than a few days.

What strikes me most is how often they move. In September 2026 the diesel cap went from €2.024 on the 3rd to €2.123 on the 12th, rose to €2.160 on the 17th and fell back to €2.055 on the 23rd before settling at €2.095. Unleaded moved between €1.792 and €1.898 in the same month. The table shows a selection of recent changes.

How to read the price at the pump

As a ceiling. If the pump shows the STATEC maximum or a little below it, that’s normal. You can compare stations to save a few cents, but in a country this size it isn’t worth a long detour. What I would do is check STATEC’s series before the trip, because it gives you a reliable idea of what you’ll pay.

One useful detail. The shop opening hours law in force since 19 June 2026 excludes motorway filling stations from its limits, just as it excludes shops in railway stations and at the airport. Each station sets its own hours.

What does 100 km cost?

The Mobility Ministry runs an official comparison that turns prices into euros per 100 km, using the average consumption of new cars registered in the country and each month’s average price. For August 2026 it gives €10.92 on 95 unleaded, €11.87 on diesel, €5.09 on LPG, €11.08 on hydrogen and €4.50 in an electric car.

I think it’s the fairest way to compare, because it looks at the cost of the journey rather than just the litre. And in August 2026, 100 km on diesel cost nearly a euro more than on petrol. For electric cars, the calculation assumes 80 % of charging happens at home, so a visitor charging on public points will pay more than that figure.

Budgeting a road trip

The per-100 km figures make budgeting simple. Using the official August 2026 estimate, a 300 km tour of the north and the Moselle in a typical petrol car would come to roughly €33 in fuel, and about €36 in a diesel. That’s my own multiplication of the ministry’s figure, not an official quote, and your car’s real consumption will shift it up or down. August itself shows how quickly things move, too. The unleaded cap stood at €1.689 on 12 August, €1.727 on the 15th and €1.748 on the 26th, while diesel climbed from €1.798 on 7 August to €1.963 on the 20th.

What you’ll find at the pump

The official comparison only covers fuels sold in Luxembourg, and the list helps avoid picking the wrong nozzle. It shows diesel B7, 95 unleaded E10, LPG, hydrogen and electricity. If your hire car runs on petrol, it’ll normally take 95 E10, but check the filler cap or ask the firm before filling up.

If you’re hiring a car

Check the fuel type on the rental agreement before you set off, as mixing up petrol and diesel is an expensive mistake to fix.

If your contract asks you to return the car full, STATEC’s maximum lets you compare the firm’s refuelling charge with what you’d pay yourself. Where the desks are and when they open is in car hire in Luxembourg.

What I won’t tell you

I won’t compare the price with the UK or with the neighbouring countries, because I have no official source doing it on the same date, and prices move too fast to trust a figure from another day. Nor will I recommend a particular station, in Echternach or anywhere else. For speed limits see driving in Luxembourg, and for city car parks and zones, parking in Luxembourg.

If you would rather go at your own pace, see the car hire deals in Luxembourg: the earlier you book, the more cars are left to choose from.

Before you fix your dates, compare tickets to Luxembourg: the same journey can cost very different amounts from one day to the next.
