Iceland Gas Prices: Where to Actually Find the Cheapest

The national average tells you what to budget. It doesn't tell you where to actually fill up. Here's what genuinely moves the price you pay, and the two free tools that show today's real numbers by station.

Check a live tracker before you fill up

Brand reputation isn't a reliable guide. Icelandic sources tracking this closely are explicit that the cheapest brand, N1, Orkan, Ólís, or Atlantsolía, changes week to week and station to station, not by any fixed pattern. Two free, genuinely live sources cover all of Iceland's roughly 247 stations:

• gasvaktin.is, an open, crowd-sourced price comparison project covering every station brand, with historical trend data if you want to see how prices have moved.
• bensinverd.is, a live comparison service that lists current self-service prices in ascending order, typically refreshed every few minutes.

Check one of these the morning you're actually filling up, not days ahead, prices move often enough that a number from earlier in the week can already be stale.

The one reliable exception: Costco

Iceland has a single Costco station, in Kauptún next to the IKEA just outside Reykjavík. Unlike the brand-to-brand price race, Costco has consistently priced meaningfully below the national average in 2026 data, around 193 ISK per liter (roughly $1.56) against a national average closer to $1.77–$1.79. The catch: you can only buy fuel there with a Costco membership, which runs about 5,000 ISK (roughly $49) per year in Iceland. If you're not already a member and won't get other value from one, the membership cost likely erases the fuel savings on a single trip. If you are a member, or you're stocking up on other things anyway, it's worth the detour before a long drive.

Fill up in the capital area before you leave it

This matters more than brand choice. Stations in and around Reykjavík are consistently your cheapest, most reliable option; remote stations along the Ring Road and especially in the Highlands run higher and can occasionally run short on fuel entirely. One current source estimates the capital-versus-remote price spread can save roughly 3,900 ISK, about $32, across a single Ring Road tank, just from choosing where you fill up rather than what brand you choose.

If your route touches any F-road, plan around this specifically: the Highlands interior has exactly one fuel pump, at Geysir. See Iceland F-Roads Explained for opening windows, and fill your tank fully before heading in.

What actually drives your fuel cost more than brand choice

Per-liter price differences between stations are real but small next to two bigger factors: how far you drive, and what you drive. A one or two liter per 100km difference in vehicle consumption compounds over a full trip into a much bigger swing than any station-to-station price gap. Use the Iceland Driving & Fuel Cost Planner to see your actual total for your specific route and vehicle, current pump price already factored in.
