Cheapest diesel stations in Brittany
How to find the cheapest gas in Brittany?
Rennes is the region's most competitive city with many supermarket stations. The further west you go (Finistère, coastal Morbihan), the higher prices climb. In northern Finistère and on the islands (Belle-Île, Groix), prices can run 15 to 25 cents above the national average. Fill up in Rennes or Brest before heading to the coast.
The Je Carbure Malin app locates every station around you in real time and ranks them by price. Free on iOS and Android, it uses official data from the French Ministry of Economy, updated several times a day.
Which fuel should you choose in Brittany?
E85 is scarce in Brittany, especially in rural areas. SP95-E10 remains the most accessible fuel in terms of price and availability across the whole region.
In general: diesel remains cost-effective on long trips thanks to its better energy efficiency. SP95-E10 suits almost all vehicles made since 2000 and is cheaper than regular SP95. E85 is the cheapest fuel per liter — but it burns faster, which cuts the real-world savings to about 20-30% depending on the vehicle.
