Spanish drivers are paying up to 30 euros more each time they fill up with diesel, information from new figures from Transport & Environment (T&E). The rising cost is adding to the financial burden on households and businesses.
Spain relies on diesel more than almost any other country in Europe. Diesel engines power 52% of all vehicles on Spanish roads. Only four countries have a higher share: Lithuania and Portugal, followed by Croatia and Latvia. Eurostat reports that EU diesel prices jumped 8.3% in August 2026 alone, with Spain recording one of the sharpest increases in the bloc. By mid-September 2026, the average price of diesel in Spain had reached 1.87-1.93 euros per liter. A full 50-liter tank cost 94-97 euros.
Truck drivers are feeling the impact most acutely, paying over 236 euros more for fuel each week. Higher costs are changing the economics of transport and logistics, pushing up the price of goods and making Spanish industry less competitive. The International Road Transport Union says market prices are only part of the spike: Spain’s temporary excise reduction to 179 euros per 1,000 liters and the 200-euro rebate for professional diesel were both scheduled to end on September 30, 2026, adding to the surge.
Across Europe, the diesel premium is draining 200 million euros from people’s pockets every day. Spain stands out because so many vehicles run on diesel and the fleet is old: 60% of Spanish vehicles have been on the road for more than ten years. Older engines use more fuel, which raises costs at the pump. By mid-September 2026, average diesel and gasoline prices across the EU were close to record highs, information from the European Commission’s Weekly Oil Bulletin. That adds to the pressure on Spanish consumers.
Private drivers are also affected. Diesel cars make up 38% of European passenger cars, and the average Spanish driver now faces a much bigger bill at every fill-up. The cost is even higher for those with cars over 15 years old. These vehicles account for 30% of the European diesel fleet. T&E says that if the diesel premium continues through Christmas, the EU will have spent as much as it would cost to give every owner of an old diesel car a 2,000-euro scrappage bonus.
Isabell Büschel, director of T&E España, says: “Each diesel vehicle we replace with an electric one saves another thousand liters of oil.” The transition is slow, and the costs are being felt now.
Spain has struggled for years to modernize its fleet and cut diesel use. As reported earlier, the country is still trying to build up its electric vehicle industry, but progress is slow.
Most vehicles still run on diesel, and many are well past their best years. Spanish drivers remain exposed to global price swings and rising costs. The crisis reflects years of slow policy and limited fleet renewal. Unless Spain speeds up the move to cleaner, more efficient vehicles, the financial hit for households and businesses will keep getting worse.
