The Cheapest Fuel Border Crossings in Europe, Updated Weekly

Fuel is the same product on both sides of every border in Europe. What changes at the line is the tax on it — and this week, on 72 land crossings we price both sides of, that difference is worth up to €27.90 on a single 50-litre tank.

This report is rebuilt every time our prices refresh, from the week of 2026-07-20. Nothing below is typed by hand.

The twelve crossings where filling up on the other side pays most

Andorra against France is the standout: petrol at €1.45 a litre versus €2.01. A driver who lives near that border and fills a 50-litre tank once a week is looking at roughly €1,450.80 a year for the inconvenience of crossing it.

\* 2 crossings are marked because one side currently fails our own plausibility check — Finland, Norway report a pre-tax price that does not match the rest of the continent, so the tax split for that crossing cannot be trusted. The pump prices are sound and the row stays in the table, but no claim above is based on it.

Most of what you save is tax, not fuel

Across the 35 crossings where both countries report a pre-tax price, an average of 49% of the price gap is duty and VAT rather than the fuel itself. On 20 of them, tax accounts for more than half the difference.

This is the part that surprises people. Petrol trades on one global market; the stuff going into the tanker is priced within a few cents a litre whether it is bound for Andorra or France. What you experience as "cheap fuel over there" is almost always a decision taken in a parliament, not a refinery.

It also means these gaps are stable in a way that market-driven ones are not. Crude moves weekly; excise duty moves when a government changes it, which is rarely. A crossing that pays this week will very likely still pay next month.

Where the border makes no difference

Not every line on the map is worth crossing. The flattest crossings in Europe right now:

• Slovakia vs Czechia — €0.01/L
• North Macedonia vs Bulgaria — €0.01/L
• Slovenia vs Croatia — €0.01/L
• Switzerland vs France — €0.02/L
• Croatia vs Montenegro — €0.02/L

At these differences a detour of more than a few kilometres costs more in fuel than it saves. Our comparison pages work out the break-even distance for each crossing so you do not have to.

How to read these numbers

Every price here is a national average including all duties and taxes, not a station price. Two caveats worth holding onto:

• Border forecourts price for the border. A station in sight of a crossing knows exactly why you stopped, and prices accordingly. The saving is usually real, but you may need to drive a few kilometres past the first sign to collect it.
• The cheaper country can flip between fuels. Petrol and diesel carry different duty rates, so the winner on one is not automatically the winner on the other. Each comparison page flags this when it happens.

Prices come from the European Commission's Weekly Oil Bulletin and national sources — see our methodology. All 111 countries we cover are in the full price table, and the complete list of crossings is ranked by gap.
