Fuel is the second-largest cost of an Iceland road trip after the rental itself, and it is the one most people fail to budget for properly. It is also the source of two specific problems visitors run into: unattended self-service pumps that reject foreign cards, and stretches of road where the next station is 120 km away.
What fuel actually costs in 2026
Iceland fuel prices are among the highest in Europe, driven by import costs and taxation. Prices move with global oil markets, so treat these as a planning range rather than a quote — check the pump on the day.
| Item | Typical 2026 figure | Notes |
|---|---|---|
| Petrol (95 octane) | ~300–340 ISK per litre | Varies by chain and location |
| Diesel | ~300–340 ISK per litre | Most rental 4x4s in Iceland are diesel |
| 50-litre fill | ~15,000–17,000 ISK | Typical SUV tank |
| Ring Road, ~1,600 km | ~130 litres, 40,000–45,000 ISK | At about 8 l/100 km |
| Road tax | 7 ISK per kilometre | Charged separately from fuel |
| Highlands / F-roads | Add 20–30% consumption | Low gears, gravel, 4x4 engaged |
Rural stations, especially in the Westfjords and the east, are usually a few krona per litre more expensive than the Reykjavik area. The difference is small enough that it is never worth risking an empty tank to chase a cheaper pump.
The chains and how they differ
N1 is the largest network and the one you will see most often outside the capital. Many N1 sites have a shop, hot food and toilets, which makes them the default road trip stop. Olis and its unattended sister brand OB are the second network. Orkan is generally the cheapest of the mainstream chains and mostly unattended. ON operates electric charging. Costco in Gardabaer near Reykjavik has by far the lowest prices but requires a membership card.
Discount cards exist for all the chains and shave a few krona off per litre. For a one-week trip the saving is marginal; for a three-week trip it is worth asking at the first station whether they offer a visitor card.
How Icelandic pumps actually work
Outside the capital area, most stations are unattended around the clock. The sequence is: insert card, enter PIN, select an amount, fill, and the unused pre-authorisation is released.
Three practical warnings. First, you need a card with a PIN — contactless and signature-only cards frequently fail at Icelandic pumps. Second, many machines pre-authorise a large amount, sometimes 20,000 ISK or more, which is held against your balance for a few days. Third, if you plan to select a fixed amount rather than fill up, remember that you cannot get change on a prepaid selection at most unattended pumps.
Prepaid fuel cards, sold in the shops of most staffed stations, are the reliable fallback if your bank card is refused. Buying one 10,000 ISK card at the start of a trip is cheap insurance.
The stretches where you must not pass a station
Iceland has real gaps. The rule that keeps travellers out of trouble is simple: in rural Iceland, refuel whenever you drop below half a tank, regardless of what your range display says.
| Stretch | Approximate gap | Fill up at |
|---|---|---|
| Egilsstadir → Myvatn (eastern plateau) | 165 km, nothing between | Egilsstadir or Reykjahlid |
| Hofn → Djupivogur | 105 km | Hofn |
| Vik → Kirkjubaejarklaustur | 70 km, but sparse either side | Vik |
| Kirkjubaejarklaustur → Hofn | 200 km with limited options | Kirkjubaejarklaustur |
| Westfjords: Patreksfjordur → Isafjordur | Long gaps, limited opening hours | Every station you pass |
| Kjolur F35 and highland routes | No fuel at all on the route | Before entering the highlands |
| Melrakkasletta / Langanes, north-east | Very sparse | Husavik or Thorshofn |
The highlands deserve special mention: there is no fuel on the F-roads. Kjolur, Sprengisandur and the routes to Landmannalaugar all require you to enter with a full tank and enough range for the whole crossing plus a margin, because gravel and low-range driving increase consumption by 20 to 30 percent.
Road tax: the charge people forget
Iceland applies a per-kilometre road tax of 7 ISK on top of fuel cost. It is a genuine budget line, not a rounding error: 1,600 km of Ring Road adds about 11,200 ISK, and a 2,200 km trip with detours adds around 15,400 ISK.
Plan for it the same way you plan for fuel. It is also worth remembering when comparing rental quotes — a cheap headline daily rate on a thirsty vehicle can cost more overall than a slightly higher rate on an efficient one.
How to use less fuel in Iceland
The speed limit is 90 km/h on paved rural roads and 80 km/h on gravel, which is already in the efficient range for most vehicles. Beyond obeying it, the biggest savings come from planning: group your sightseeing geographically instead of doubling back, avoid engaging 4x4 mode on dry paved roads, and remember that headwinds on the south coast can raise consumption dramatically on an exposed day.
Roof boxes are a false economy in Iceland. The wind penalty on fuel is significant and the risk of wind damage is real. If you need the space, take a larger vehicle instead.
Electric cars and charging
Iceland has a growing charging network run mainly by ON and Isorka, concentrated along Route 1 and in the capital area. For a summer Ring Road trip in a modern EV it is workable with planning. For winter travel, remote regions, gravel roads or the highlands, a diesel 4x4 remains the practical choice — cold reduces range, and a charger that is occupied or out of service in a village of 200 people is a serious problem.
Choosing a vehicle with fuel in mind
Fuel cost scales directly with the vehicle you pick. A SsangYong Tivoli or Dacia Duster will use noticeably less than a Toyota Hilux or a 9-seat bus over 1,600 km. If your itinerary is paved-road sightseeing, the smaller vehicle saves twice — lower daily rate and lower fuel. If you are heading onto gravel or travelling in winter, take the 4x4 and budget for the extra consumption; it is the correct trade.

Frequently asked questions
How much does fuel cost in Iceland in 2026?
Roughly 300–340 ISK per litre for both petrol and diesel, meaning a 50-litre fill costs about 15,000–17,000 ISK. Prices are a few krona higher in remote areas than around Reykjavik.
What is the Iceland road tax of 7 ISK per km?
It is a per-kilometre charge applied in addition to the cost of fuel. Over a 1,600 km Ring Road trip it adds roughly 11,200 ISK, so it belongs in your budget as a separate line.
Will my credit card work at Icelandic fuel pumps?
Only if it has a PIN. Unattended pumps, which is most rural stations, routinely reject contactless and signature-only cards. If your card fails, buy a prepaid fuel card inside a staffed station — carrying a 10,000 ISK prepaid card is sensible insurance.
Where are the longest gaps between fuel stations?
The Egilsstadir to Myvatn plateau is about 165 km with nothing in between. Kirkjubaejarklaustur to Hofn, the Westfjords fjord roads and the north-eastern peninsulas also have long gaps. There is no fuel at all on highland F-roads.
How much fuel does the Ring Road use?
About 130 litres for roughly 1,600 km in a mid-size 4x4 at 8 litres per 100 km, so around 40,000–45,000 ISK. Gravel and highland driving raise consumption by 20 to 30 percent.
Should I rent an electric car in Iceland?
For a summer trip on Route 1 with planning, it works. For winter, remote regions, gravel roads or the highlands, a diesel 4x4 is the practical choice — cold cuts EV range and rural chargers are sparse.
