We had arrived in Norway with a full tank, knowing that Norway is probably the most expensive place in the world to buy fuel. But we knew that full tank wouldn't last us for our entire time here, and yesterday was the day to pay up.
Like most other places in the world, the price at the pump tends to fluctuate with the world price of oil. I've noticed here in Norway there is a bit of a delay in implementing that fluctuation, and the oil price is now off its peak. But the price at the pump here hasn't dropped.
