Petrol prices in Mallorca: Where you can really compare reliably

If you live in Mallorca and fill up regularly, you'll know the feeling: on one street corner the price seems fair, a few kilometres further on a completely different figure is showing on the pump. Prices per litre here often change several times a week, sometimes shifting significantly from one day to the next – most recently, for instance, amid geopolitical crises that briefly pushed the oil price upward. That's precisely why this guide deliberately gives no current figure: any price per litre would be outdated within a few days and would mislead you. Instead, you'll learn that there is a legally established, official price database, who is required to feed it with data, how reliable it really is – and where its limits lie. By the end, you'll know how to find the up-to-date price near you in seconds yourself, without chasing after an outdated table.

Why this article doesn't state any prices per litre

Fuel prices in Mallorca are as volatile as almost no other everyday expense. The Mallorcan press documented in March 2026 how a military escalation in the Middle East pushed the petrol price up by around 14 percent within a week, and the diesel price by as much as a quarter – at individual petrol stations on the island, the most expensive and cheapest offers differed markedly at the same time. A figure that appears in a guide today could therefore already be wrong next week. A price comparison ranking based on individual petrol station brands would also be misleading, because the order of the cheapest providers is constantly shifting.

What remains is the question of where you can look things up reliably and with up-to-date figures. This is exactly what Spain has an official system for – and it is more robust than any snapshot in an article.

The legal basis: mandatory reporting for petrol stations

Price information at Spanish pumps is not a voluntary service but a legal requirement. The basis for this is the Real Decreto-ley 6/2000, de 23 de junio, on urgent measures to intensify competition in goods and services markets. The explanatory memorandum of the regulation makes clear that petrol stations are obliged to report the prices they actually charge – expressly for the purpose of informing consumers. Article 5 of this regulation establishes the price information system that to this day forms the basis for any serious price check in Spain.

This is complemented by the Real Decreto-ley 15/1999, de 1 de octubre: on state roads and motorway access points, signs indicating distance, fuel type, price and brand are actually required. This obligation is considered fulfilled if the operator instead joins the price information system, so that users can retrieve the information via mobile phone or another telematic means. This is the actual legal reason why the digital price check exists at all: it replaces the roadside sign.

The official price information system – how it works

The reported prices are collected by the responsible ministry and made accessible to the public there – as the "Price Information System for Fuels" (on the ministry's website miteco.gob.es). In practice, this means you select the fuel type, narrow it down to your location or postcode, and are shown the most recently reported prices of petrol stations in the area. Because reporting is legally mandatory rather than voluntary, this source is generally more reliable than private price comparison sites or anecdotal reports on social media, which only ever show a snapshot from individual users.

Note: The price shown is the most recently reported price at the petrol station – not a guarantee that this exact amount will be shown at the pump the minute you arrive. There may be a price change between the report and your fuel stop that hasn't yet been reflected.

How often is it reported? The reporting frequency in detail

The ministry's FAQ on the price reporting system reveals when a report is considered compliant: in the event of a technical fault in the system, the obligation is deemed fulfilled if the report is submitted by the following Monday at the latest or upon the next price change – whichever comes first. From this, the regular reporting frequency can be deduced: petrol stations report with every price change, but at least once a week.

Limits of the database: why some petrol stations are missing

As reliable as the system is in principle, it has an important limitation that surprises many users. The reporting obligation applies exclusively to the fuels expressly listed in the Orden ITC/2308/2007 and its annexes. If a product cannot be selected in the query, there is simply no obligation to report it.

Even more important: a wholesaler is only required to report a petrol station's prices if that station belongs to its exclusive network. If a station is not tied in this way, then in doubt no one reports its prices – and the Ministry itself cites this as the reason why individual petrol stations may be missing from the database. So if you can't find your regular petrol station in the query, this is usually not due to a technical error but to this legal construction.

Note: If a petrol station is missing from the query, this does not automatically mean it is evading its reporting obligation – it often simply doesn't fall under the exclusive network of a wholesaler subject to reporting requirements.

Monitoring and sanctions: who checks the reporting obligation?

To ensure the reporting obligation doesn't remain merely theoretical, the legislator tightened controls in 2026. The CNMC (Comisión Nacional de los Mercados y la Competencia) includes a dedicated section in its monthly report on fuel distribution at petrol stations that assesses the degree of compliance with the reporting obligation – including a list of sanctions imposed. This report must be published within 20 days of the end of the month. There is therefore a publicly accessible oversight body that verifies whether petrol stations and wholesalers are actually fulfilling their reporting obligations.

In addition, a new article was introduced providing for enhanced monitoring of gross margins in fuel distribution – a tool that allows authorities to keep a closer eye on conspicuous price mark-ups along the supply chain.

Temporary additional reporting requirement until the end of 2026 – what currently applies

Since Real Decreto-ley 18/2026, de 29 de junio, an additional, explicitly time-limited reporting obligation applies: wholesalers must submit by 31 December 2026 weekly report their procurement costs and retail prices to the CNMC. The CNMC forwards this information to several ministries. Once this fixed period has ended, the CNMC is to establish a permanent reporting system with a comparable level of information – it will determine the content, frequency and procedure itself. What this successor system will look like in concrete terms is not yet clear at this point in time.

How to find the current price near you

Instead of a fixed figure, here's the route to the right information:

1. Open the price information system of the responsible ministry (miteco.gob.es).
2. Select the fuel type you need – petrol and diesel are available as separate categories.
3. Narrow your search to your municipality or postcode so that you only see petrol stations within reach.
4. Compare the displayed, most recently reported prices – and keep in mind that they may have changed since being reported.
5. For unusually low or high figures, check whether the station may have recently made a change that hasn't yet reached the system.

Full-service or self-service: an everyday difference

On Mallorca you'll find both full-service petrol stations and self-service stations where you pay and fill up yourself. The fact that this difference in operating concept exists is common knowledge on the island – however, the official database doesn't automatically provide a reliable, verified statement about how big any actual price difference between the two forms really is. So it's better to rely on the price shown in the system for the relevant station than on a blanket rule of thumb.

Why driving around the island rarely pays off

Mallorca is a manageable size, and the distances between where you live and the nearest petrol stations are usually short. A detour of several kilometres to fill up at a supposedly cheaper pump often eats up, through the extra fuel consumption and time spent, exactly what it was meant to save. The real saving doesn't lie in chasing prices across the island, but in briefly checking the official database before setting off and specifically heading for a petrol station that's already on your planned route.

It stands to reason that fuel on an island generally comes with additional transport and storage costs – however, reliable, verified figures on how much this actually translates into compared with the mainland are not available for this article. If you're taking your vehicle to the garage regularly anyway, you might as well have your tyre pressure checked at the same time – low tyre pressure unnecessarily increases consumption. You can find a suitable garage near you in the Industry directory: car repair workshops.

Most common mistakes when comparing prices

• Relying on a single figure from a blog article. Price-per-litre figures are outdated within days – only the official, continuously updated lookup shows the current state.
• Interpreting a missing petrol station as an error. A common reason is the lack of an exclusive tie to a reporting-obligated wholesaler, not a technical oversight.
• Driving larger detours for small price differences. On an island of this size, the extra fuel consumption often eats up the savings again.
• Equating the reported price with the price at the pump. There can be a change between the reporting and the actual fill-up.
• Assuming price spikes are permanent. Short-term fluctuations, for example as a result of international crises, are not automatically the new price level.

What comes next?

The current, time-limited additional reporting obligation for wholesalers to the CNMC runs until 31 December 2026. After that, the CNMC is due to introduce a permanent successor system with comparable information content. Exactly what the content, reporting frequency and format of this permanent system will look like is determined by the CNMC itself – this has not yet been decided at this point in time. Anyone who regularly fills up on Mallorca should keep an eye on this announcement, without relying today on specific details that are not yet fixed.

If you're registering your vehicle on the island right now anyway, or thinking about switching to electric mobility, it's also worth taking a look at the charging infrastructure: Charging an electric car on Mallorca.

Checklist: comparing fuel prices on Mallorca correctly

• Use the ministry's official price information system as your first point of reference, not social media screenshots.
• Don't treat a missing petrol station in the lookup as an error, but as a possible consequence of the lack of an exclusive tie.
• Do a quick comparison before longer journeys, but don't plan detours for small differences.
• Classify short-term price spikes (e.g. due to international crises) as temporary.
• Have tyre pressure and vehicle condition checked regularly so as not to unnecessarily increase consumption.
• Keep an eye on changes to the reporting obligation after 31.12.2026, once the CNMC specifies its successor system.

Conclusion

There's no serious reason to give you a price-per-litre figure here – any number would be wrong within a short time. What matters is knowing that Spain, with the reporting obligation dating from 2000, created a robust, legally secured system that has since been expanded and, since 2026, has additionally been supplemented by stricter monitoring from the CNMC. This official source is the only place where you'll find a truly up-to-date price comparison for Mallorca – with the one caveat that not every petrol station is automatically listed. Anyone who knows this saves themselves detours, doesn't rely on outdated figures, and fills up wherever it actually makes sense at the moment.
