Our weekly recap for Spain has not appeared since 2 August: an error in our event detector and too strict a publishing rule held it back. Both were corrected on 11 October 2026. This recap covers the period from 3 August to 10 October 2026; from now on the recap appears every Sunday when the national average of diesel or petrol moves by at least 0.3% over the week.

About the data
The national average is the unweighted mean of the prices reported each day by at least 10,800 stations, for Gasóleo A (B7) and Gasolina 95 E5, from Geoportal de Hidrocarburos (Ministerio para la Transición Ecológica y el Reto Demográfico, MITECO). A day on which far fewer stations than usual report is left out of our series. Percentages are calculated from unrounded averages; prices are rounded to two decimals, and fill-up differences are calculated from the prices shown. How we calculate.
