Fuel prices in Spain on 14 July 2026: Where is the cheapest petrol and diesel?

As of 14 July 2026, petrol and diesel prices in Spain continue to be a top agenda item for drivers. Due to market fluctuations and growing concerns over household spending, choosing the right station to buy fuel makes a big difference to your wallet. According to average prices across the country, 95-octane petrol is trading at 1,54 euro, 98-octane petrol at 1,72 euro, and Grade A diesel at 1,55 euro.

Chains such as Costco, Alcampo, Ballenoil, and Petroprix, which keep their costs low compared to major operators, stand out by offering fuel at prices well below the average. In contrast, although companies like Repsol charge higher prices, they continue to be preferred thanks to their loyalty cards and additional services. Furthermore, due to tax differences between regions and local competition, price differences per litre can reach up to 40 cents in cities like Las Palmas, Madrid, and Barcelona.

For drivers to save money, platforms such as the Ministry for Ecological Transition's geographic information portal (Geoportal), ClickGasoil, and MiCarburante.com instantly show the nearest and most affordable stations. Planning fuel purchases using such digital tools has become an effective strategy for reducing daily transportation expenses.
