In May 2025, one gallon of diesel cost an average of 3.5 U.S. dollars in the United States. That was a decrease compared to the month prior, and also lower than prices in May 2024. Impact of crude prices on motor fuel consumer prices Diesel prices are primarily determined by the cost of crude oil. In fact, crude oil regularly accounts for around 50 percent of end consumer prices of diesel. As such, supply restrictions or weak demand outlooks influence prices at the pump. The fall in diesel prices noted in the latter half of 2024 is a reflection of lower crude prices. Diesel and gasoline price development The usage of distillate fuel oil began in the 1930s, but until further development in the 1960s, diesel vehicles were mostly applied to commercial use only. In the U.S., diesel-powered cars remain a fairly small portion of the automobile market and diesel consumption is far lower than gasoline consumption. In general, gasoline also tends to be more widely available than diesel fuel and usually sells for a lower retail price. However, diesel engines have better fuel economy than gasoline engines, and, as such, tend to be used for large commercial vehicles.

The average price for regular gasoline in the United States stood at **** U.S. dollars per gallon on June 30, 2025. This compared to a diesel price of **** U.S. dollars per gallon. Prices for gasoline decreased that week following a fall in crude oil prices. Real price surge of 2022 and 2023 still below 2011 to 2014 prices When looking at the real price of gasoline over time, U.S. drivers had to pay notably more in the years between 2011 and 2014. The surge in prices noted throughout 2022 and partly for 2023, which followed supply constraints, was still lower in terms of real U.S. dollars. U.S. on the lower-end spectrum of worldwide motor fuel prices The U.S. has some of the lowest conventional motor fuel prices in the world. Although fuel prices are usually higher in high-income countries, the U.S. profits from its position as the world’s largest crude oil producer and can keep retail prices for oil products comparatively low. For example, among high-income countries, prices for automotive premium gasoline (RON 95) were only lower in Russia and Saudi Arabia - countries where crude oil and oil product exports are in part restricted by sanctions, thus keeping domestic supply high.

The cost of diesel fuel in the United States reached an annual average of 3.76 U.S. dollars per gallon in 2024. This was a decrease compared to the previous year, when diesel sold for an average of 4.21 U.S. dollars per gallon. In 2022, increased economic activity and thus fuel demand combined with supply constraints following the Russia-Ukraine war, which resulted in a notable rise in monthly diesel prices Crude oil prices and their impact on motor fuel prices Motor fuel prices largely mirror major oil benchmarks, such as the OPEC reference basket, WTI, and Brent. As such, the oil glut in 2015 and 2016, which followed years of increased oil production output by the U.S., is largely responsible for the fall in diesel prices seen in those years. The same is true for the 2020 pandemic-induced oil crisis and fall in benchmarks that year. Diesel and gasoline price development The usage of diesel began in the 1930s, but until further development in the 1960s, diesel vehicles were mostly used commercially. In the U.S., diesel-powered cars remain a fairly small portion of the automobile market and diesel fuel consumption is far lower than gasoline consumption. In general, gasoline also tends to be more widely available than diesel fuel and usually sells for a lower retail price. However, diesel engines have better fuel economy than gasoline engines, and as such are often used for large commercial vehicles.

Crude oil is the greatest cost component determining diesel retail prices in the United States. In February 2025, 49 percent of the diesel retail price was set by crude oil costs. That month, one gallon of diesel sold for an average of 3.68 U.S. dollars. U.S. diesel prices have generally stagnated in early 2025. Fuel consumption remains high despite higher prices Diesel and gasoline prices have experienced significant fluctuations over the past decades. In 2024, the average gasoline price stood at 3.3 U.S. dollars per gallon, a decrease from the 2022 peak but still higher than early 2000s levels. Despite these changes, U.S. gasoline consumption has remained high, averaging around 8.5 million barrels per day in 2024, with seasonal variations affecting demand. Tax impact on fuel costs across states Taxes play a significant role in determining fuel prices, with state-level differences creating notable price variations across the country. As of 2023, the average state tax for gasoline was 30.5 U.S. cents per gallon, while diesel faced a slightly higher average tax of 33.15 U.S. cents. These taxes contribute to the overall retail price and are often reinvested in road infrastructure. California, for instance, imposes some of the highest gasoline taxes in the country, reaching 68.1 U.S. cents per gallon in January 2024, which significantly impacts the state's fuel prices.

Average consumer prices are calculated for household fuel, motor fuel, and food items from prices collected for the Consumer Price Index (CPI). Average prices are best used to measure the price level in a particular month, not to measure price change over time. It is more appropriate to use CPI index values for the particular item categories to measure price change.

Prices, except for electricity, are collected monthly by BLS representatives in the 75 urban areas priced for the CPI. Electricity prices are collected for the BLS for the same 75 areas on a monthly basis by the Department of Energy using mail questionnaires. All fuel prices include applicable Federal, State, and local taxes; prices for natural gas and electricity also include fuel and purchased gas adjustments.

Diesel price fluctuations

Between Spain, Germany, France, United Kingdom, Italy, Japan, the U.S. and Canada, there is a lack of consistency in the monthly change in the price of automotive diesel. Canada's prices decreased by over 22 percent between June 2020 and June 2019, whereas prices in the United Kingdom only fell by around 16.2 percent. All changes were a direct result of falling oil prices amid the coronavirus pandemic.

Diesel fuel in the United States

The monthly retail price of diesel fuel in the U.S. had seen only slight fluctuations in the months between June 2019 and January 2020. However, when crude oil demand began falling due to the pandemic, so did diesel retail prices. Figures slumped to a low of 2.39 U.S. dollars per gallon in May 2020. Crude oil accounts for, on average, about 40 to 50 percent of the share of the total cost of diesel in the U.S. Texas sold the highest volume of diesel and alternative fuel of any state in 2018. That year, they sold about 5.91 billion gallons of diesel.

The mean B20 retail fuel prices in the United States amounted to three U.S. dollars per gasoline gallon equivalent on January 1, 2024. This compared to 3.16 U.S. dollars for regular diesel fuel, making it the lowest price for such fuels since October 2021. B20 fuel is a diesel blend with 20 percent with biodiesel content. The higher the biodiesel content, the more expensive the fuel on the retail market. B100 sold for a mean retail price of 3.85 U.S. dollars in January 2025. B20 has been the cheapest option since October 2017.
