Best Day to Fill Your Tank and Save on Fuel Costs 2026

If you're wondering what day is best to fill your tank and save a few euros, the answer is simple: yesterday. With fuel prices climbing and no good news coming from the Strait of Hormuz, filling up sooner rather than later is the most straightforward advice we can give.

Gasoline prices are skyrocketing, and some service stations are already selling diesel well above two euros per liter. While we're not at historic highs yet, the trend is worrying.

Current Fuel Prices in Spain

According to data from dieselgasolina.com, a portal that monitors prices reported by service stations, average fuel prices in Spain are as follows:

These prices are still far from the peaks we saw in 2022, when gasoline 95 exceeded an average of 2.15 euros per liter and "cheap" diesel reached 2.10 euros per liter. Now, some stations are already selling diesel above that figure.

Government Intervention: From Subsidies to Tax Cuts

In response to rising prices and a transport strike, the government decided that starting in March 2022, the state would subsidize fuel purchases with 20 cents per liter for all drivers. The goal was to ease the burden on consumers facing sudden price increases across all types of products.

Now, the government has opted for a different strategy. Faced with the new price hike, it has introduced a tax reduction instead of a direct subsidy. This means the discount is applied through taxes rather than a fixed amount per liter.

Why Timing Matters When Fuel Prices Are Rising

When prices are on an upward trajectory, waiting to fill up can cost you more. Stations adjust their prices frequently, often daily, and sometimes multiple times a day. If you wait, you risk paying the higher price.

Moreover, not all stations update prices at the same time. Some may lag behind, offering a brief window of lower prices. But relying on that is risky. The safest bet is to fill up as soon as you can when you know prices are rising.
