U.S. retail prices of diesel fuel
The usage of diesel began in the 1930s, but until further European development in the 1960s, diesel vehicles were mostly applied to commercial use only. More recently, diesel-fueled engines have become more popular as diesel engines become more efficient. In the United Kingdom, 47.7 percent of new cars registered in 2016 were fueled by diesel. However, in the United States, diesel-powered cars remain a fairly small portion of the automobile market. Diesel cars often have lower acceleration, higher costs, and a heavier weight. They may also be more difficult to start in cold weather. Gasoline also tends to be more widely available than diesel fuel. However, diesel engines have better fuel economy than that of gasoline engines, and tend to last longer as well.
As of May 2017, diesel fuel retail price in the United States reached 2.56 U.S. dollars per gallon. In comparison, gasoline cost 2.14 U.S. dollars per gallon in 2016. The price of diesel has dropped in several countries but risen in others. From January 2016 to January 2017, the retail price of automotive diesel increased by 21.1 percent in Germany. In Japan, prices increased by 5.7 percent during the same time. The United Kingdom had some of the highest prices for automotive diesel, reaching 1.50 U.S. dollars per liter in January 2017. In the United States, highway vehicles consumed nine million barrels of gasoline and 2.9 million barrels of gasoline-equivalent gallons of diesel in 2015.
