Driving into Spain for fuel does not pay off for everyone living near the Pyrenees: the price gap per litre is noticeable, but the road eats into it. The trip pays for itself where a Spanish filling station is a few minutes' drive away. The further your home is from a Spanish filling station, the faster the saving on a full tank melts down to a few euros. All calculations below use prices from 3 November 2026 and have not been recalculated since.

What is left of the saving on a full tank
At median prices on 3 November 2026, diesel (gazole) cost €2.249/L in France and €1.929/L in Spain, that is 32 c/L cheaper. SP95 petrol (E10 in the French data) came to €2.089/L against €1.739/L for Spanish Gasolina 95 E5: a gap of 35 c/L. The saving on 50 L is reduced by the fuel used for the detour there and back (6.5 L per 100 km at the local price), so the result is always less than “price gap × 50”. In Le Perthus the Spanish filling station is 5 minutes away, and a full tank of diesel saves +€14.56, SP95 +€25.84 (prices as of 3 November 2026).
Where the trip pays off
The largest numbers of worthwhile municipalities are in Pyrénées-Atlantiques (69 out of 362) and Pyrénées-Orientales (66 out of 213). Next come Haute-Garonne with 42 out of 233 and Hautes-Pyrénées with 21 out of 315. In Ariège there is just one such municipality out of 246, and Aude and Landes have none at all: the border is close, but the Spanish filling stations are far away or the route through the mountains is long.
Where to fill up on the other side
Filling stations cluster most densely around La Jonquera: 18 filling stations, and for 63 French municipalities it is the best option. At the Atlantic end the closest are Irun and Valcarlos, in Cerdagne Puigcerdà. Andorra is not included in the calculations: there are no published prices for its filling stations.
How to read your municipality's verdict
“Worth the drive” (ça vaut le détour) is given when a 50-litre fill-up saves €10 or more and the round trip takes no more than 45 minutes. Hélette gains +€22.68 on diesel, but the first Spanish filling station is 40 minutes away each way, so the verdict there is “Only if you're passing”. Journey time, wear on the car, tolls (péage) and queues at the border are not counted in the saving. Have a look at the breakdown for Le Perthus or Ainhoa; the calculation rules are set out in the methodology.
Price date and why prices differ
French prices come from the economy ministry feed, Spanish ones from MITECO's daily summary, both dated 3 November 2026; median prices by country are on the price pages for France and Spain. The gap is explained mainly by fuel taxes; tax rates are not part of the site's data.
Frequently asked questions
What is SP95 called in Spain?
Gasolina 95 E5. That is what the site compares against French SP95-E10.
Is filling up in Spain worth it with a small tank?
Less so than with a big one. The saving grows with every litre, while the fuel for the detour stays the same. The site calculates on 50 L, and with a smaller tank the same detour takes a larger share of the gain.
The essentials about filling up in Spain
At 3 November 2026 prices, Spanish diesel is 32 c/L cheaper than French, petrol 95 by 35 c/L. The trip pays off mainly in Pyrénées-Atlantiques and Pyrénées-Orientales, almost never in Ariège, Aude and Landes. Check the verdict for your own municipality: the threshold is €10 per tank and 45 minutes of detour.
