Not sure what year Dolphin's figures are from. A google showed me this at CNN Money:
This page shows April/May 06 prices.

NEW YORK (CNN/Money) – Gasoline prices in the United States, which have recently hit record highs, are actually much lower than in many countries. Drivers in some European cities, like Amsterdam and Oslo, are paying nearly 3 times more than those in the U.S.
The main factor in price disparities between countries is government policy, according to AirInc, a company that tracks the cost of living in various places around the world. Many European nations tax gasoline heavily, with taxes making up as much as 75 percent of the cost of a gallon of gasoline, said a spokesperson for AirInc.
In a few Latin America and Middle-East nations, such as Venezuela and Saudi Arabia, oil is produced by a government-owned company and local gasoline prices are kept low as a benefit to the nation's citizens, he said. All prices updated March, 2005.
So we have to factor in all these things: taxes, shipping costs, and who owns the oil, as well as cost of living and other things.
It appears that my figures are closer to the 2005 figures.
. Just goes to show that where the oil comes from is the cheapest. I don't think that the Alaskan oil fields could supply the entire US for long. However; I thought I read somewhere that an awful lot of that oil is sold to China and Japan!
