Brazilian gasoline has been artificially cheap since 2011, when President Dilma Rousseff began using price caps to help curb inflation. When Rousseff started raising those prices as part of a broad package of austerity measures, it increased the cost of living and brought more than a million people to the streets in protest.
The average daily income in Brazil is $26. The share of a day's wages needed to buy a gallon of gas is 18 percent.
Canada was once considered a leader on combating global warming. Now it's one of the biggest foot-draggers in global climate talks. The country has a lot to lose: Vast reserves of difficult-to-extract oil will mean either an environmental toll to produce or an economic toll to keep in the ground.
Canadians have relatively high incomes and low gasoline prices. As in many countries, cheap gas goes hand in hand with high consumption. Only Americans use more gasoline per person.
The average daily income is $123. It takes 3 percent of a day's wages to afford a gallon of gas.
High gasoline prices and economic uncertainty have been a shock to Fiat's and Ferrari's home country, where car ownership is among the highest in the world. The global oil crash has offered less relief in Italy than it has in most countries.
The average daily income in Italy is $84. It takes 8.5 percent of a day's wages to buy a gallon of gas.
When Europeans buy cars, Czechs go to work building them. The country manufactures more than a million vehicles a year for companies including Toyota, Volkswagen, and Hyundai.
Car purchases are a particularly strong economic barometer in the Czech Republic, where carmaking is the largest manufacturing industry. The country's average daily income is $47. It takes 11 percent of a day's wages to buy a gallon of gas.
Kuwait has one of the world's biggest gasoline subsidies, and the IMF has warned that the country will exhaust its oil savings if it continues to subsidize gasoline and social programs at the current rate.
Petroleum accounts for about half of Kuwait's GDP and 95 percent of its exports and government income.
Filling up is no trouble in Kuwait, where the average daily income is $90—enough to buy 120 gallons of gas if there were a car big enough to hold that amount. Kuwaitis are the third-biggest consumers of gasoline after the U.S. and Canada.
Lithuania's gasoline price is cheap, at least if you compare it with the “Scent of Lithuania,” a perfumer's attempt to capture the aromas of a nation. A gallon of that stuff would set you back a startling $5,000.
The average daily income in Lithuania is $40, of which 12 percent is required to purchase a gallon of gasoline.
Luxembourgers are among the world's biggest gas guzzlers. Only Americans, Canadians, Kuwaitis, and Saudis burn more fuel. But the tiny landlocked country also enjoys the highest per capita income in the world—$264 a day—making the nation's moderate gas prices among the world's most affordable.
It takes 2 percent of a day's wages in Luxembourg to buy a gallon of gas.
French automakers Peugeot and Renault have returned to earnings growth after a six-year slump in European auto sales. They may soon face competition from electric vehicles, at least in their home country, which has the world's fifth-highest EV sales rate.
Average daily income is $105. It takes 5.7 percent of a day's wages to buy a gallon of gas, or essence, as the French call it.
The Netherlands is slowly weaning itself off oil. The Dutch have the second-highest rate of electric-vehicle adoption, and hailing a taxi at the airport in Amsterdam will often bring you a Tesla.
The bike-pedaling Dutch have the highest fuel tax in the European Union and the most bicycles per capita in the world. Row upon row of them are parked at train stations, museums, and national parks. A vast infrastructure of bike lanes, tunnels, and traffic signals makes cycling easy to adopt.
The Netherlands' average daily income is $121. It takes 5.9 percent of a day's wages to buy a gallon of gas.
Slovakia, a nation of 5 million that joined the EU in 2004, relies on Russia for oil. That oil must traverse the Druzhba pipeline through Ukrainian territory, putting Slovaks in a sensitive political middle ground in the standoff between Moscow and the West.
The average daily income in Slovakia is $44. It takes 13.1 percent of a day's wages to buy a gallon of gas.
Ireland has a reputation for beer drinking. The Irish consume 277 pints a year per person, second only to the Czech Republic. They guzzle a lot of gasoline, too.
Ireland is a road-dependent economy with public transportation that's less extensive than that of most countries in western Europe. The average daily income is $130, and it takes 4.6 percent of a day's wages to buy a gallon of gas.
Argentina regulates its energy prices, both for oil producers and for gasoline consumers, so drivers have felt only limited relief from the global plunge in oil prices.
Pumping gasoline isn't the only way to fill up in Argentina. The country has 13 percent of the world's natural gas vehicles, according to trade group NGVA Europe. It's also one of the biggest producers of biofuels in the world.
The average daily income in Argentina is $36, 15 percent of which is needed to buy a gallon of gas.
Norway retains the title for the world's most expensive gas. The Scandinavian country doesn't subsidize fuel at the pump, using its oil riches instead for national services, such as free college education and savings for infrastructure improvements.
Norway's high gas prices are an electric-car maker's dream. The country has the biggest share of electric vehicles in the world: An astonishing 22 percent of new cars registered in the first quarter of 2015 were electric.
With the world's third-highest incomes, Norwegians absorb the high price of gas with relative ease. The average daily income in Norway is $221. It takes 3.5 percent of a day's wages to buy a gallon of gas.
Nigeria is one of the biggest losers from the oil crash. The country relies on oil for 75 percent of government revenue and uses its oil bounty to subsidize extremely cheap gas. The cost of those subsidies makes it difficult to invest in much-needed infrastructure and education.
Nigeria is Africa's top oil producer, but the country still faces regular fuel shortages due to hoarding and mismanagement. Nigeria's average daily income is $7.90. It takes 21 percent of a day's wages to buy a gallon of gas.
Israel caps the price of 95-octane gas while allowing other forms of the fuel to fluctuate. Average daily income in Israel is $100, of which 6.6 percent is required to buy a gallon of gas.
Australia was one of the first nations to institute a wide-ranging tax on carbon dioxide pollution. And then it became the first to revoke one.
The country's carbon tax shifted the price of energy so that wind became cheaper than coal and natural gas for producing electricity. The tax never applied to driving, which means Australians continued to enjoy relatively pain-free fill-ups at the bowser (the Aussie word for fuel pump).
The country is a gluttonous consumer of fossil fuels and has the highest per capita emissions among industrial nations. The average daily income in Australia is $144, only 3.1 percent of which is needed to buy a gallon of gasoline.
Years of economic sanctions have starved Iran of oil revenue. The country's finances got so bad that in 2010 Iran began a five-year plan to curb its popular energy subsidies. It still has some of the biggest, and with sanctions coming to an end, that will probably continue.
Iran's average daily income is $14. It takes 9.6 percent of a day's wages to buy a gallon of gas.
The cost of fuel matters very little to Singaporeans; it's the cost of the car that matters most.
In Singapore, a Volkswagen Passat will set you back almost $166,000, according to SGCarMart.com. Most of the cost is for the state-auctioned permit, which gives a driver the right to own a car for 10 years. The permits are used to limit congestion and pollution.
The average daily income in Singapore is $147. It takes 4.1 percent of a day's wages to buy a gallon of gas.
Thailand has cheap gas relative to most nations, but it's still a steep cost for many Thais. The global oil crash has benefited the nation, which has seen one of the sharpest declines in gas prices worldwide.
Pain at the pump in Thailand helped encourage wide adoption of three-wheeled auto rickshaws, known as tuk-tuks, in the country's biggest tourist cities. The open-air vehicles use less gas but are still big polluters.
Thailand's average daily income is $15. It takes 21 percent of a day's wages to buy a gallon of gas.
Life, liberty, and the pursuit of happiness. Countries have different ideas of which rights are inalienable. In western Europe, universal health care is the norm. In oil-rich Norway, college is free. Venezuela stands alone in considering cheap gasoline a birthright.
Venezuela's gas is so cheap, it shows up as free on our display. The paltry price is actually 0.13 cents a gallon. The cost of filling up a 39-gallon Chevy Suburban there is about 5 cents, compared with $106.86 in the U.S. and $300.69 in Norway.
Fuel-efficient cars don't tend to fly off the lots if it costs less to fill a tank than to buy a cup of coffee. Venezuela is a poor country that burns through gas like a rich one.
Updated, September 10: Corrects the price of of filling up a 39-gallon Chevy Suburban. It is $300.69, not $309.69.
Slovenia is a green country. Literally. Protected parks comprise 36 percent of the nation's land, and more than half the country is covered in forest.
Slovenians consume slightly more gasoline than the world average, while earning below-average wages. The country's average daily income is $57. It takes 9.8 percent of a day's wages to buy a gallon of gas.
China is the world's second-biggest oil consumer, and that's only expected to increase as the middle class expands in coming years.
But how many of China's new cars will burn gasoline? Despite its relatively low per capita income of $22 a day, China already has the second-highest number of electric vehicles in the world.
It takes almost a fifth of a day's wages to afford a gallon of gas in China. The average person's consumption isn't formidable. Combined, the entire country's is.
Chile depends on petroleum imports to fuel its economy. That reliance keeps increasing, because the country's wells are running dry and people are driving more.
It's not unusual for Chile's gas prices to buck the global trend. The country has price-adjustment tools, including a self-adjusting tax that flattens price spikes. When costs jump too high, the tax declines; when prices fall, the tax rises.
The average daily income is $38. It takes 12 percent of a day's wages to buy a gallon of gas.
Belgium has one of the more expensive gas prices, but the country's high incomes and low consumption rates mean filling up remains a minor line item in the family budget.
EU law prohibits countries from setting price controls, but Belgium does set ceilings on oil products to protect consumers from price spikes.
The average daily income in Belgium is $113. The share of a day's wages needed to buy a gallon of gas is 5.6 percent.
After reunification in 1990, Germany committed 34 billion euros to transportation infrastructure in the East. The region now boasts the finest autobahns in the nation. Pristine, pothole-free roads mean speedsters can push their BMWs to more than 155 miles per hour.
The average cost of gasoline in Europe is more than double the price in the U.S. A German driver filling the 13.2-gallon (50-liter) tank of Europe's most popular car, Volkswagen's Golf, pays $81.97, compared with $36.17 for the same fill-up in the U.S.
Hong Kong is part of China but has its own constitution, political structure, and gas price. On average, Hong Kong residents pay 75 percent more for a gallon of gas than their neighbors in China, where the government caps the price.
Hong Kong and China are both among the world's smallest consumers of gasoline per capita. Hong Kong drivers, with their higher urban incomes, feel less pain at the pump. In fact, residents there spend a smaller proportion of their annual paychecks filling up than the people of any other country except Venezuela.
The average daily income is $116. It takes 6.5 percent of a day's wages to buy a gallon of gas.
Poland has a relatively low gas tax by European standards. That hasn't stopped fuel tax fraud, which costs the country millions every year, according to Europol.
Poland relies on Russia for 90 percent of its oil imports and more than 80 percent of its natural gas. The country is trying to shift to cleaner energy sources, but coal still accounts for about 55 percent of its energy supply, the highest in Europe.
Poland's average daily income is $35. It takes 14 percent of a day's wages to buy a gallon of gas.
Spain is a leader in renewable energy. It's the first country in the world to have wind as its top energy source for an entire year, and it now consistently gets the majority of its electricity from carbon-free sources.
The plunging price of oil can be a drag for oil-producing countries, but Spain isn't one of them. It imports nearly all of its oil, gasoline, and natural gas. Government regulation limits fuel imports from any one country to ensure a diverse supply.
Spain's average daily income is $73. It takes 7.6 percent of a day's wages to buy a gallon of gas.
Indonesia started 2015 by scrapping a large swath of its unaffordable fuel subsidies, which have been blamed for slowing social and economic development for years.
The changes are profound, but with the global slump in oil prices, most people haven't yet felt the effects at the pump. The true test of government discipline and public willingness to go along will arrive the next time oil prices swing upward.
The average daily income in Indonesia is $9.62. It takes 29 percent of a day's wages to buy a gallon of gas.
There's relatively little rotten in the state of Denmark. It has the least income inequality, the happiest people, and the least corruption in the world, according to recent research.
Copenhagen, the capital, is also among the most bike-friendly cities in the world. More than 50 percent of Copenhageners commute to work or school by bicycle. The world's busiest bike lane—Dronning Louises Bro—hosts 36,000 bicyclists every day.
Denmark's gasoline ranks among the most expensive, but filling up there remains affordable. Average daily income is $145, and it takes 4.8 percent of a day's wages to buy a gallon of gas.
The Philippines is shifting to a manufacturing and services economy from one based primarily on agriculture. Energy demand is high. Wages aren't.
The Philippines consumes a small fraction of the gasoline used by most other countries in the ranking. The nation's average daily income is $8.32, and it takes almost half a day's wages to buy a gallon of gas.
Finns are some of the world's fastest drivers. Maybe it's the caffeine, which Finns consume three times more of (26 pounds per person every year) than Americans.
The Finnish record on the race track is no less excessive. Finns have won the World Rally Championship more than any other nationality and have won more Formula One championships proportional to their population than any other nationality.
A high gas price is little bother in a nation where the average daily income is $117. It takes 5.6 percent of a day's wages to buy a gallon of gas.
The Saudis sit atop two enormously valuable bodies of liquid: oil and water. Both are being pumped to the surface at unsustainable rates.
Saudi Arabia is OPEC's biggest oil producer and heavily subsidizes its steady gasoline price. Saudis rank among the biggest gas guzzlers in the world but devote among the smallest shares of their incomes to buying it.
The average daily income in Saudi Arabia is $57. It takes 0.8 percent of a day's wages to buy a gallon of gas.
Turkey is coal country. It sits above an estimated 14 billion tons of coal reserves, among the world's top 10 deposits. At a time when most countries are reducing their dependence on coal, Turkey plans to massively expand its reliance by 2020.
In recent years, Turkey has increased its revenue base through consumption taxes. The country's gasoline tax is one of the highest in the world.
Turkey's average daily income is $27. It takes 25 percent of a day's wages to buy a gallon of gas.
With high incomes and some of the cheapest gasoline around, Americans have little to complain about at the gas station. Imagine shelling out $7.71 a gallon, the price in Norway. Indians and Pakistanis must put in almost a full day's work, on average, to afford a single gallon.
No one can compete with the U.S. when it comes to burning gasoline. Americans guzzle 1.2 gallons per person each day, more than any other country by a long shot. Even with falling gas prices, America's thirst for the open road can take a toll on budgets.
The average daily income in the U.S. is $155. It takes just 1.8 percent of a day's wages to afford a gallon of gas.
Energy prices in Sweden are subject to taxes on tailpipe pollution, including carbon dioxide, the most consequential greenhouse gas. Filling stations there are required to sell alternative fuels, such as ethanol, to help reduce the country's dependence on oil.
The country's average daily income is $136. It takes 4.6 percent of a day's wages to buy a gallon of gas.
Latvia, which regained independence from the Soviet Union in 1991, still depends on Russia for almost all its energy needs. That hasn't stopped the country from supporting stiff sanctions against Russia.
About a quarter of Latvia's population considers itself Russian, and the country has one of the biggest ethnic divides in the Baltics. Latvia was a key terminal for Russia's oil exports until the opening of Russia's port at Primorsk and the Baltic Pipeline System. Those projects drastically diminished Latvia's role.
The average daily income in Latvia is $38. It takes 13 percent of a day's wages to buy a gallon of gas.
Croatia, which joined the EU in 2013, is seeking to expand exploration of oil and natural gas supplies in the Adriatic Sea. Last year, Croatia joined Hungary and Ukraine to create a natural gas corridor to curb Europe's reliance on Russian fuel.
Average daily income is $32. It takes 18 percent of a day's wages to buy a gallon of gas.
Adrift between Italy and Libya, the tiny island nation of Malta has relied on imports for virtually all of its energy. Now it's seeking to open its waters to oil exploration.
The average daily income is $61. It takes 9.1 percent of a day's wages to buy a gallon of gas.
Japan's long-standing national gasoline tax helped the country's carmakers take an early lead in developing fuel-efficient vehicles. It's home to half of the world's fast-charging stations for electric vehicles and now has more EV charging points than gas stations.
Japan's average daily income is $91. It takes 4.8 percent of a day's wages to buy a gallon of gas.
With the third-highest incomes in the ranking, the Swiss can afford to splurge a little on gasoline. And they do.
Despite that indulgence, the Swiss maintain some green credentials. Investments in hydroelectric, nuclear, and wind power leave them with a carbon dioxide emission rate that's less than half the average of OECD nations.
The average daily income in Switzerland is $230. It takes 2.9 percent of a day's wages to buy a gallon of gas.
Kiwis consume a lot of gasoline—the seventh most per capita in the ranking. The country also has the world's fourth-highest rate of car ownership.
The average daily income in New Zealand is $115. It takes 4.8 percent of a day's wages to buy a gallon of gas.
Russia's economy is being hit by a triple whammy of sanctions from the West, a crash in oil prices, and falling internal demand for fuel.
Russia is the world's third-biggest oil producer and enjoys some of the cheapest gasoline prices on the global market. The country's average daily income is $22. It takes 11 percent of a day's wages to buy a gallon of gas.
Ask Bulgarians if gas is expensive, and they'll likely shake their head. Because in Bulgaria, shaking your head means yes (and nodding means no).
An average daily income of just $20 a day and middling gas prices have helped make it a burden for Bulgarians to fill up. It takes 25 percent of a Bulgarian's daily wages to buy a gallon of gas—the seventh-most acute pain at the pump in this ranking.
A trip to the pump is painful in Pakistan, where workers must put in almost a full day's work, on average, to afford a gallon of gasoline.
Most Pakistanis opt for cheaper compressed natural gas (CNG), which fuels about 80 percent of the nation's auto fleet. Pakistan has about 2.8 million CNG vehicles on the road, the most of any country, according to NGVA Europe, a trade group for makers of natural gas vehicles.
Pakistan is the poorest country in the gas-price index, with an average daily income of $3.68. It takes 79 percent of a day's wages to buy a gallon of gas.
Romanian gas consumption is a quarter of the ranking's average. The average daily income in Romania is $26, and it takes 21 percent of a day's wages to buy a gallon of gas.
The montado landscape of Portugal produces more than half the world's cork. Careful management of cork oak trees, whose bark is harvested every nine years, allows the trees to survive for hundreds of years.
The gasoline tax is one of several levies expanded in Portugal since 2001 to fund such environmental protection measures. Taxes on vehicles account for carbon dioxide emissions and engine cylinder capacity, and have led to a more efficient fleet on the road.
Gas taxes are lower in neighboring Spain, leading some Portuguese drivers to cross the border to fill up. Portugal's average daily income is $53. It takes 12 percent of a day's wages to buy a gallon of gas.
Estonians use less gasoline than the global average, but given their relatively low incomes, the fuel bill still takes a toll on family budgets.
Estonians do save gas money on one occasion: voting day. Estonia was the first country in the world to use Internet voting. The average daily income is $48, and it takes 9.8 percent of a day's wages to buy a gallon of gas.
Mexican subsidies and favorable foreign exchange rates once tempted U.S. drivers to cross the border to fill up. Those days are gone. Mexico, the world's seventh-biggest oil producer, has been chipping away at its fuel subsidies, and pump prices are creeping up.
Of all the OECD member countries, only the U.S. charges less in gas taxes than Mexico. The average daily income in the country is $28. It takes 12 percent of a day's wages to buy a gallon of gas.
Egypt's finances are in disarray, and super-cheap gas is mostly to blame. The Arab world's most populous nation spends about $13 billion on fuel subsidies a year. The government plans to gradually reduce those subsidies, though past attempts to do so have rankled public opinion and ultimately failed.
The average Egyptian income is $9.05 a day. It takes 14 percent of a day's wages to buy a gallon of gas.
Since the discovery of oil in the United Arab Emirates in the 1960s, the U.A.E. has evolved from a poor region of principalities to a wealthy modern state with a high standard of living.
For decades, billions of the U.A.E.'s oil bounty has gone to subsidizing fuel each year. That's changing, with a new pricing policy linked to market rates. Reducing subsidies is easy with oil at rock-bottom prices; the true test will come when the cost of a barrel goes up again.
The average daily income in the U.A.E. is $104. It takes 1.6 percent of a day's wages to buy a gallon of gas.
South Africans face a lot of pain at the pump, which is exacerbated by how much gasoline they consume. In no other country do people spend more of their paychecks fueling up.
The rand's weakness compared with the dollar has also been expensive for motorists. Prices in South Africa are set monthly by the Central Energy Fund, a state-owned entity established in 1997.
South Africa's average daily income is $16. It takes 26 percent of a day's wages to buy a gallon of gas.
India has edged past Pakistan for the least affordable fuel in the world. In both of these countries, low wages and limited infrastructure result in widespread energy poverty. Quality of life is hampered by limited access to electricity and clean fuels.
Prime Minister Narendra Modi has taken advantage of the global slump in oil prices to reduce the country's budget-draining energy subsidies. The price of diesel, for example, will now fluctuate with the global market.
The average Indian would have to spend 80 percent of his daily income to afford a gallon of gasoline. Due to the cost, this country of 1.2 billion people has the lowest per capita consumption.
Electric vehicles are booming in the U.K., which now boasts the third-highest EV sales rate in the world, according to market researcher IHS. EVs make a lot of sense in a country with short driving distances and one of the highest gasoline prices in the world.
The U.K.'s average income is $120. It takes 5.7 percent of a day's wages to buy a gallon of gas.
Malaysia's extensive fuel subsidies give it one of the cheapest gas prices in the ranking, even after the country reduced payouts last year. But cheap fuel offers little comfort in a nation dealing with the economic turmoil of being one of China's biggest trading partners.
The average daily income in Malaysia is $29, 7.1 percent of which is needed to buy a gallon of gas.
Austrians buy less gasoline and pay less for it than the European average.
The average daily income in Austria is $122. The share of a day's wages needed to buy a gallon of gas is 4.1 percent.
Falling oil prices are bad news for Colombia, which relies on crude for half of its exports.
Colombia saw a relatively large decline in gasoline prices since the oil crash at the end of last year. Still, Colombians have been consuming ever more per person, and the total income spent on gas is on the rise.
The average daily income in Colombia is $19. It takes 17 percent of a day's wages to buy a gallon of gas.
Greece is still struggling to dig itself out of the financial crisis that almost drove the country from the European Union. To help rein in debt, Greece has been raising gasoline taxes since 2009, to rates that are now among the highest in Europe.
Greeks' pain at the pump is worsened by the amount they consume. Only South Africans spend more of their annual incomes to fill up their cars.
Average daily income is $52. It takes 13 percent of a day's wages to buy a gallon of gas.
Production of Hungary's oil and natural gas resources has peaked and is expected to continue to decline, according to the Organisation for Economic Co-operation and Development. More than 80 percent of the country's oil is now imported from Russia.
Hungarians really pay for it. The country's average daily income is $35—15 percent of which is required to buy a gallon of gas.
Despite being one of the world's smaller nations—roughly the size of Indiana—South Korea ranks high in cars. Hyundai and Kia are fifth in the world by combined global sales.
South Korea's average daily income is $78. It takes 6.9 percent of a day's wages to buy a gallon of gas.
Island nations like Cyprus generally pay more to have fuel delivered. With above-average gas prices, low incomes, and lots of driving, Cypriots devote the fourth-largest share of their annual incomes to fueling up.
The average daily income of a Cypriot is $60. It takes 9.2 percent of a day's wages to buy a gallon of gas.
