Gas prices in Iceland are pretty extortionate, to say the least. Most people are surprised when they arrive and fail to prepare for fuel costs.

If you're driving the ring road, there's every chance you may end up spending more on fuel than the actual car rental. 

There are many gas stations over the island, and various companies such as N1, ÓB and Orkan. But currently, the cheapest gas station in Iceland is *drum roll please* COSTCO!

When Costco first opened, their fuel was
listed at 169.9 per liter. At that time, the
closest competitor was 185.7 per liter.

Pretty incredible! And whilst the price has
risen now due to gas prices inflating, it is
still by far the cheapest in Iceland.

The main issue is that Costco requires a membership for purchasing gas, so most tourists will avoid it.

But don't threat! There are still some other great options within Reykjavík such as Spöngin over in Grafarvogur which regularly has fair prices and also Skemmuvegur. 

When returning your rental vehicle, you will be required to return it with a full tank. There is a gas station at the car rental area of the airport called 'Orkan', this would be the best location for you to fill up as if you fill up further away you may use too much gas and the agency may charge you for this.
