July 7, 2026 Fuel Prices in İspanya: Where to Find the Cheapest Gasoline and Diesel?

Fuel prices for drivers in İspanya continue to be a closely monitored topic due to the constantly changing energy market and rising household expense concerns. As of Tuesday, July 7, 2026, the cost of filling up a vehicle varies significantly depending on the type of preferred station and even the city where one is located. While gasoline and diesel prices have followed a fluctuating course in recent weeks, regional differences and the price gap between brands have become highly pronounced. Especially for daily drivers, being able to make these price comparisons has turned into a serious saving strategy. Drivers are forced to research the current tariffs of different stations in order to protect their budgets.

According to the latest data published by the geographic data portal of the Ministry for Ecological Transition, average fuel prices across the country have stabilized at a certain level. According to this data, a liter of 95-octane unleaded gasoline is offered at an average price of 1,52 Euro. The average price of 98-octane unleaded gasoline stands at 1,70 Euro. Meanwhile, the liter price of Type A diesel fuel has been recorded at an average of 1,53 Euro. Although these average values create a reference point in the market, the actual sales prices determined by the stations themselves can be significantly below or above these figures.

For those looking to find the most affordable fuel in the market, chains such as Costco, Alcampo, Ballenoil, Plenergy, Superco, and Petroprix stand out. By offering gasoline and diesel prices well below the national average, these brands attract drivers looking for significant savings. For example, at a Costco station located in Zaragoza, diesel fuel can be purchased for 1,432 Euro/liter, and 95-octane gasoline for 1,443 Euro/liter. On the other hand, large and widespread operators like Repsol continue to be preferred by many customers, as they offer additional services, loyalty cards, and mobile app discounts, even though they keep their prices above average. This situation requires consumers to make a choice between preferring just price or service quality.

Differences in fuel prices are not limited to station brands; they can also reach dramatic proportions among different autonomous communities and cities within İspanya. In major metropolitan areas such as Madrid, Barselona, and Valencia, the price difference per liter can reach up to 40 cents even within the same city limits. While the price of 95-octane gasoline in Madrid ranges from 1,39 Euro to 1,77 Euro, in Barselona these figures fluctuate between 1,29 Euro and 1,72 Euro. This intense variability is a direct result of various factors such as tax policies applied by local regions, regional competitive conditions, and the proximity to logistics centers and ports. Therefore, choosing different districts within a city to purchase the same fuel can provide a significant economic advantage.

Various digital tools and platforms are of vital importance for drivers to achieve maximum savings every time they fill their tanks. Platforms such as the official geographic portal of the Ministry for Ecological Transition, ClickGasoil, and MiCarburante.com instantly show users the most affordable stations based on their location. Those aiming to save, especially in large cities like Madrid, can easily find low-cost stations in the southern and eastern regions through these applications. These digital applications are completely free and have become indispensable guides for those looking to optimize their traffic costs. Conscious drivers are making the right fuel purchases just as much a fundamental part of their budget management as vehicle maintenance and driving habits.
