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 July 7, 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.

Diesel prices in the United Kingdom rose to more than *** pence per liter in early 2024. The March national average was ***** pence per liter, compared with a price of ***** pence per liter for diesel sold at supermarkets. Hypermarkets dominate motor fuel sales Hypermarkets such as Sainsbury's, Asda, and Tesco have the greatest market share of motor fuel sold in the UK. In 2023, roughly ** percent of all motor fuels were sold at hypermarkets. Diesel more expensive than regular gasoline Although gasoline and diesel are both refined petroleum products, their refining process differs, thus also impacting manufacturing and retail prices. Diesel sold in the UK is required to have an ultra-low sulfur content and also contain a biodiesel component of seven percent. The extra steps required in the production process make diesel a more expensive commodity than gasoline, which trades around ** pence lower.

On July 7, 2025, the price of ultra-low sulfur unleaded petrol (gasoline) in the United Kingdom averaged 133.19 pence per liter. This compared to 140.58 pence per liter for diesel. Diesel prices were consistently higher than petrol/gasoline prices throughout this period, although the margin varied. Reasons for such differences in pricing lie in the refining process and molecular makeup of the products, with diesel requiring more complex refining processes and being an overall heavier liquid. As motor fuel pricing in the UK is not regulated by a monitoring body, there may also be notable differences in prices between retailers and regions. Supermarkets provide lowest fuel prices in the UK In the UK, much of the motor fuel is sold through supermarkets. Large supermarkets, or hypermarkets, account for more than 40 percent of all motor fuel sales in the country. The reason for their popularity often lies in the fact that they offer lower average prices. In the last four years, regular petrol/gasoline sold at supermarkets was up to six pence per liter cheaper than the national average. How UK fuel prices compare to the rest of the world Tied as they are to crude oil prices, motor fuels are generally cheapest in major producing countries, such as Iran, Venezuela, and Russia. In Europe, costs of importing the raw or finished products, in addition to taxes and levies, may hike up pump prices significantly. The UK is often among the countries with the highest petrol/gasoline prices, alongside other large European car markets such as France and Germany.

The global fuel energy price index stood at 153.15 index points in May 2025, up from 100 in the base year 2016. Figures decreased that month due to lower heating fuel demand and a fall in crude oil prices. The fuel energy index includes prices for crude oil, natural gas, coal, and propane. Supply constraints across multiple commodities The global natural gas price index surged nearly 11-fold, and the global coal price index rose almost seven-fold from summer 2020 to summer 2022. This notable escalation was largely attributed to the Russia-Ukraine war, exerting increased pressure on the global supply chain. Global ramifications of the Russia-Ukraine war The invasion of Ukraine by Russia played a role in the surge of global inflation rates. Notably, Argentina bore the brunt, experiencing a hyperinflation rate of 92 percent in 2022. The war also exerted a significant impact on global gross domestic product (GDP) growth. Saudi Arabia emerged with a notable increase of nearly three percent, as several Western nations shifted their exports from Russia to Middle Eastern countries due to the sanctions imposed on the former.

In April 2025, the average diesel retail price in Canada stood at ****** Canadian cents per liter. This was the steepest month-over-month fall in prices since 2020, with a similar development echoed by Canada's monthly gasoline prices.

On July 1, 2025, the price of regular gasoline was highest in California, at around **** U.S. dollars per gallon. This was some *** dollars above the national average of **** U.S. dollars. California's high motor fuel prices are largely determined by it being the U.S. state with the highest gasoline tax. Tax impact on pump prices As of January 2024, California's gasoline tax reached **** U.S. cents per gallon, far exceeding rates in other states. This tax burden plays a crucial role in shaping retail prices, with federal and state taxes being one of the strongest determinants of what consumers pay at the pump. The revenue generated from these taxes is typically reinvested in road infrastructure, demonstrating the direct link between fuel costs and transportation development. Winter months see lowest prices While taxes significantly influence gasoline prices, crude oil costs remain the primary factor, accounting for ** percent of the retail price in February 2025. The volatility of crude oil prices directly impacts pump prices, as seen in the fluctuations over recent years. Conventional motor fuel prices, including gasoline and diesel, are generally lowest in the winter months. This is due to generally lower demand during those months, as well as the winter fuel blend being less expensive to produce than the summer alternative.
