Fuel in the Canary Islands is among the cheapest in western Europe, routinely well under what the same litre costs on the Spanish mainland and dramatically less than in Britain or Ireland. Filling the tank of a small hire car here is a genuinely cheap transaction, and it changes what a day out costs: a full circuit of Lanzarote or Fuerteventura uses a few euros of petrol, not twenty.
There are two reasons, and they compound. The first is tax. The islands sit outside the EU VAT area and charge their own much lower sales tax instead — IGIC, at a general rate of 7 per cent against the mainland's 21 per cent IVA. The second, and larger, is excise duty: the special fuel duty levied in the archipelago is set far below the peninsular rate, part of the long-standing economic settlement that compensates the islands for being a thousand miles from anywhere.
The result is a pump price that makes British visitors take a photograph of the display. Treat any specific figure as 2026 framing rather than a promise — fuel prices move weekly with the oil market — but the gap between here and the mainland is structural and reliable, and the gap between here and the UK is very large indeed.
Petrol or diesel? Get the word right
This is the one that costs people a four-figure repair bill, because the two Spanish words are almost the same:
- Gasolina is petrol. The grade you want is sin plomo 95 — unleaded 95 — which is what almost every hire car takes. Sin plomo 98 is the higher-octane version, dearer and unnecessary unless the car specifically calls for it.
- Gasóleo is diesel. It is also sold as diésel or gasóleo A. Gasóleo B is agricultural, dyed, and not for road cars.
Gasolina and gasóleo differ by two letters. Say the wrong one to an attendant who is holding the nozzle and looking at the pump rather than at you, and the wrong fuel goes in. Nozzle colours vary by brand and are not a reliable guide, so the safe habit is to read the fuel-filler flap, which almost always states the grade, and to say the grade number out loud: sin plomo noventa y cinco, lleno, por favor — unleaded 95, fill it up, please.
Misfuelling is almost never covered by a hire car's damage waiver. It is classed as negligence, and the bill for draining a tank and flushing a fuel system runs into several hundred euros before any tow. This is the single most expensive five-second mistake available to a visiting driver.
Attended service is normal here
Most Canarian filling stations still have attendants, and on many forecourts you are not expected to touch the pump at all. You pull up, someone comes over, you say the grade and either lleno (full) or a euro amount, and they fill it while you sit in the car. Then you either pay them or go inside to the kiosk.
There is no surcharge for this and no tip is expected — a euro left for someone who has also cleaned your windscreen is generous rather than customary. For a visitor it is quietly civilised, and it also means someone competent is choosing the nozzle, which reduces the misfuelling risk considerably.
Self-service stations exist, particularly the low-cost chains and the 24-hour automated pumps, and are becoming more common. Where a forecourt is unattended overnight you pay at a machine first, selecting the pump number and an amount, then fill. Cards work; some machines pre-authorise a larger sum and refund the difference, which can sit on a statement for a few days.
Who sells the fuel
Alongside the Spanish majors you will notice a brand that exists nowhere else: DISA, a Canarian-owned fuel distributor with a large share of the island forecourts and no real presence outside the archipelago. Cepsa, Repsol and a scattering of independents and discounters make up the rest.
Price differences between brands are small but real, and the discounters are cheapest. Spain's Ministry for Ecological Transition publishes a live national price comparison covering every station in the country, islands included, which is the honest source if you want to find the cheapest pump near you rather than trusting a forecourt sign. In practice the variation across an island is a few cents a litre and rarely worth a detour.
How to pay
Cards are accepted essentially everywhere, contactless included. A few very small rural stations still prefer cash, so it is worth carrying twenty euros in notes if you are heading into the interior of La Gomera or El Hierro.
On attended forecourts the sequence is usually: they fill, you go to the kiosk, you say the pump number, you pay. On some you pay the attendant directly at the car with a handheld terminal. Neither requires any Spanish beyond the pump number and gracias.
The rural range problem
Petrol stations cluster along the main roads and around the towns. Head into the mountains or out to the far ends of the islands and they disappear, and the ones that exist keep shop hours rather than motorway hours — closed for the middle of the day in some villages, closed on Sundays, closed in the evening.
This matters on specific drives. The road out to Punta de Teno, the long empty run down to Morro Jable and the Jandía peninsula, the loop through the high centre of Gran Canaria, and almost anything on the smaller western islands are all journeys where you want to start with more than a quarter of a tank. The rule of thumb islanders use is simple: fill up when you are in a town and the gauge is at half, not when you are in the hills and it is at a quarter.
On El Hierro and La Gomera there are only a handful of filling stations on the whole island. Note where they are on your first day. Running dry on a road with no phone signal and one car an hour is a long afternoon.
Mountains, altitude and what they do to consumption
Canarian roads go up. A drive from the coast to the Teide national park climbs more than two thousand metres, and a small hire car with four people and the air-conditioning running will drink fuel on the way up in a way that bears no relation to its official figures. Plan on consumption being noticeably worse than the brochure on any island day that involves a summit.
The compensation comes on the way down, where you can coast and engine-brake for half an hour and use almost nothing. Use a low gear rather than riding the brakes: the descents from Teide, from Roque Nublo and from the passes above Masca are long enough to overheat brakes badly, and the smell of cooking pads on a mountain layby is a common island experience. The wider road-craft is in driving in the Canary Islands.
Fuel policies on a hire car
The pump price is only half the story; the other half is what your rental contract says about the tank. Two models exist:
- Full to full — you collect it full and return it full. This is the fair one and the one to look for. The established Canarian firms have traditionally made a selling point of it.
- Full to empty, sometimes dressed up as a "fuel service" — you pay the company for a tank at their price, plus a service charge, and return it as empty as you dare. You will almost always lose money on this, because nobody ever returns a car genuinely empty.
Fill the tank yourself at a station a few kilometres from the airport rather than the one directly outside it, keep the receipt, and photograph the fuel gauge at both collection and return. The whole family of rental add-ons, including this one, is unpicked in car hire excess insurance and the upsells, and the broader booking advice sits in hiring a car in the Canaries.
Why the islands got cheap fuel in the first place
The low duty is not a modern tourism sweetener. It descends from the puertos francos settlement of 1852, when the Spanish government declared the Canarian ports free of customs duty in an attempt to rescue an isolated, impoverished archipelago whose export crops had collapsed. That free-port principle survived every subsequent reorganisation and lives on inside the modern Régimen Económico y Fiscal, the body of special tax law the islands retain within Spain and which the EU formally recognises.
Fuel was one of the categories that stayed favourably treated, on the reasoning that an island economy dependent on road transport, desalination and shipping cannot absorb peninsular energy costs. So the cheap tank of petrol in your hire car is, in a small way, a nineteenth-century decision still working — the same decision that makes the rum and the electronics cheap.
What it means for your budget
Concretely: hiring a small car for a week and driving it enthusiastically around one island will typically cost less in fuel than a couple of restaurant meals. That is the arithmetic that persuades most visitors to hire, and it is the reason the islands reward touring in a way that a more expensive destination does not. Set against the daily hire rate, insurance and parking, the petrol is close to a rounding error.
It also means the marginal cost of the extra detour — the viewpoint twenty kilometres away, the beach on the other coast — is almost nothing. Take it. For how fuel fits into everything else you will spend, see our running figures on what things cost in the Canaries.
The short version
Fuel here is cheap for solid historical reasons, attendants will usually fill the car for you at no extra cost, and the only thing that can really go wrong is saying gasóleo when you meant gasolina. Check the filler flap, say the grade number, fill up in towns rather than in the hills, insist on a full-to-full policy, and enjoy one of the few places in Europe where the price on the pole is a pleasant surprise.
