Prices for gasoline and diesel fuel vary a great deal around the world, because some countries tax these goods heavily, while others subsidize them. Lucas W. Davis considers the effects in "The Economic Cost of Global Fuel Subsidies," published in the May 2014 issue of the American Economic Review: Papers & Proceedings (104:5, pp. 581–585).

Here's a graph showing gasoline prices in countries around the world, on the horizontal axis, and gasoline consumption per year, per person, on the vertical axis. The size of the circle for each country is proportional to total consumption of gasoline in that country. Thus, for example, the U.S., Canada, and Kuwait are roughly similar in their per capital consumption of gasoline, but because of the much larger population of the United States, the circle denoting U.S. consumption is larger. Similarly, although per capital consumption of gasoline is much lower in India and China than in the United States, the much larger populations of those countries mean that total consumption of gasoline is larger--as shown by the size of the circles for those countries.
Of course, many factors will affect fuel consumption in an economy besides the after-tax price: fro example, countries with higher per capita GDP tend to consume more fuel, and countries that are large and sprawling will tend to consume more fuel for transportation than smaller countries where more people live in urban areas. Still, a couple of themes from this graph catch my eye.
1) The price of gasoline in the U.S. is well below that many other high-income countries. That isn't the only reason the U.S. consumes so much more fuel on a per capita basis--as a high-income and geographically sprawling country, one would expect U.S. fuel consumption to be higher--but it's one of the reasons. The higher taxes on gasoline are part of a general pattern where the governments of most high-income countries rely more heavily on consumption taxes, including value-added taxes as well as taxes on specific goods like gasoline, than does the U.S. government.
2) Venezuela has the lowest fuel prices of any country: indeed, their prices are well below the actual world market price. Presumably, the political leadership in Venezuela believes that its political base supports this policy--and this belief may well be correct. But subsidizing fuel has a cost, which in Venezuela's case is about $14 billion out of a GDP of $380 billion--that is, almost 4% of GDP in Venezuela goes to fuel subsidies. For comparison, the U.S. defense budget is projected to be 3.6% of GDP this year. When Venezuela spends, in proportional terms, the amount of the U.S. defense budget on fuel subsidies, it give up the possibility of spending those funds on health care, education, income support, and so on. Indeed, the bulk of fuel subsidies don't go to the poor--who don't have enough income to buy a lot of fuel at any price--but instead go to those with middle- and upper-level incomes.
3) Worldwide, governments spend about $110 billion annually on fuel subsidies. Of that amount, 90% is for the ten countries listed in the table below. By the measure used here, the U.S. does not subsidize oil and gas production on an overall basis, given the mixture of gasoline taxes on one side and various ways of favoring oil-producers in the tax code on the other. Davis writes: "Fuel subsidies also have a large impact on government budgets, requiring taxes to be higher than they would otherwise, and inhibiting the ability of government to address other fiscal objectives. Expenditures on energy subsidies in many of these countries exceed public expenditures
on health, education, and other key components of government spending."
4) Not all major oil exporters subsidize fuel. As Davis writes: "Prices are at or above market in Iraq ($2.95 per gallon for gasoline), Mexico ($3.26), Russia ($3.74), and Canada ($5.00)."
