Iceland Fuel Price Index

The current index

Across every tracked station, bensín95 today spans 180.3 ISK/L (cheapest) · 222.3 ISK/L (average) · 228.9 ISK/L (most expensive) — and the cheapest diesel right now is 204.6 ISK/L at Costco Iceland (Kauptún).

That spread — often 30–40 ISK a litre between the cheapest and priciest pump — is why where you fill up matters as much as when. On a full tank the gap is real money. Prices refresh from gasvaktin.is roughly every hour.

How fuel is priced in Iceland

Fuel is sold by the litre and the price you see on the sign is per litre, in Icelandic króna — the number on the pole is the whole story, no per-gallon conversion needed. Two grades cover almost every rental: bensín95, 95-octane unleaded petrol, and dísel. Put bensín95 in a petrol car and diesel in a diesel; the filler cap or the key tag on a rental tells you which, and getting it wrong is an expensive mistake the insurance won't cover.

Iceland's pump prices are among the higher ones in Europe, and it's mostly tax and logistics — heavy fuel duty and carbon charges, plus the cost of shipping every drop to an island in the North Atlantic. From 2026 a per-kilometre road charge took over part of what fuel tax used to cover for many vehicles, which shifts the total cost of a trip; our kilometre-fee guide works through what that means for a rental.

Self-service, card-only pumps and PINs

Nearly every station is self-service — you fill the tank yourself and pay at the pump or, at unmanned stations, at an automat before you fill. Full-service forecourts with an attendant are effectively gone. The pumps are card-operated and most ask for a 4-digit PIN, so a card without one can simply be refused, which catches out a lot of North American visitors.

One more quirk: unmanned pumps often place a pre-authorisation hold — a temporary block larger than your actual fill (sometimes tens of thousands of króna) that clears in a few days once the real amount settles. Use a card with headroom, know your PIN before you leave the city, and pack a backup card. It's worth putting a PIN-enabled card on your packing list next to the waterproofs.

The brands, and the discount keys

Six names cover almost every forecourt: N1 and Olís are the big staffed networks with shops and services; ÓB is Olís's unmanned discount brand and Orkan runs a mix of staffed and automated sites; Atlantsolía is a lean discount chain; and Costco in Garðabær is usually the single cheapest litre in the country if you hold a membership. As a rule of thumb, the fewer the staff and the plainer the site, the cheaper the fuel.

Each network runs a discount key or app (a dælulykill fob, or the N1, Orkan and Atlantsolía apps) that shaves a few krónur off the litre and lets you pay at unmanned pumps. For a two-week trip the saving is modest but free to set up. Don't build your route around it, though — a station that's 20 ISK/L cheaper beats a 3 ISK/L app discount at your usual brand every time.

Diesel versus petrol for a road trip

At the pump, diesel and bensín95 sit close together and trade places week to week — the live numbers above show which is ahead today. The bigger lever is efficiency: a diesel car burns noticeably fewer litres per 100 km, so over a full Ring Road loop a diesel often costs less to run even when the sticker price is similar. If you're choosing a rental mainly for a long lap of the island, that efficiency usually matters more than a couple of króna on the sign.

Whatever you drive, the honest rule for Iceland is don't run it low. Stations thin out fast once you leave the southwest, and a half-empty tank in the highlands or the east is a planning problem, not an adventure. Check whether your route is open today and the live alerts before committing to a long empty stretch.
