Diesel Fuel Price: National Average Trends

what is the national average diesel fuel price

The national average diesel fuel price is a topic of interest, especially for those in the transportation industry and those who rely on diesel-powered vehicles. As of January 6, 2025, the average diesel price in the United States was 3.51 US dollars per gallon, compared to 3.06 US dollars per gallon for regular gasoline. This price comparison highlights a notable difference between diesel and gasoline costs. Diesel fuel prices have experienced fluctuations over the years, with a surge in prices observed in 2022 and partially in 2023 due to supply constraints. The US, being the world's largest crude oil producer, generally maintains lower retail prices for oil products compared to other high-income countries.

Diesel price breakdown by cost composition

The retail price of diesel fuel is affected by various factors, including federal, state, and local taxes, as well as local market conditions and the location of the fueling station. The cost components of diesel fuel vary over time and across different regions of a country.

In the United States, the federal excise tax for on-highway diesel fuel is 24.30 cents per gallon, and the federal Leaking Underground Storage Tank fee is 0.1 cents per gallon. As of January 1, 2024, the average total state taxes and fees for on-highway diesel fuel were 34.74 cents per gallon. Sales taxes and local and municipal government taxes also contribute to the final selling price.

The transition to ultra-low-sulfur diesel (ULSD) fuel in the United States has affected diesel fuel production and distribution costs. The federal excise tax on diesel fuel is 6 cents higher per gallon than the tax on regular-grade gasoline, contributing to the overall cost of diesel fuel in the country.

The average price of diesel fuel has historically been lower than regular gasoline. However, worldwide demand for diesel and other distillate fuel oils has increased, particularly in China, Europe, and the United States. This rise in demand has influenced the cost composition of diesel fuel.

In the United Kingdom, average diesel prices hit a record high during the summer of 2022, with a litre of diesel costing 199.09p. At this time, taxes represented around 43-44% of the total price paid by drivers.

How diesel prices compare to regular gasoline

The US Energy Information Administration (EIA) releases weekly updates on gasoline and diesel fuel prices. These prices include all taxes.

Diesel fuel prices are typically higher than gasoline prices. This trend can be observed in the historical US motor gasoline and diesel fuel price data. However, there have been instances where the average diesel retail price has fallen below that of gasoline, such as in 2008 and 2009.

Several factors contribute to the higher cost of diesel fuel. One factor is the taxes imposed on diesel fuel. In the US, diesel fuel is taxed at a higher rate than regular gasoline. These taxes are included in the pump price that consumers pay.

Another factor influencing diesel prices is the cost of crude oil, which is a significant component of the overall price. The price of crude oil is determined by global supply and demand dynamics and can fluctuate, impacting the prices of both gasoline and diesel fuels.

Additionally, the production and refining processes for diesel fuel can also affect its price. The refining process for diesel fuel may involve additional steps and costs compared to gasoline production. Moreover, the availability and supply of diesel fuel in the market can influence its price.

While diesel fuel prices generally remain higher than regular gasoline prices, various factors, including taxes, crude oil prices, production costs, and market dynamics, influence the price differential between the two fuels. These factors are subject to change and can impact the relative prices of diesel and gasoline over time.

The impact of winter storms on diesel prices

Extreme winter weather events, such as storms, snow, and ice, can significantly impact diesel prices. Winter storms can disrupt the diesel supply chain in several ways. Firstly, refineries may be forced to shut down or reduce production due to extreme weather conditions, decreasing the supply of diesel fuel and leading to higher prices. For example, winter storms in Texas shut down refineries, causing a jump in national diesel prices to $3.143 per gallon, the highest in almost two years.

Secondly, winter storms can damage pipelines and transportation routes, delaying fuel deliveries to gas stations and consumers. This disruption to transportation can also increase freight activity as industries try to stock up on products and materials before the cold weather hits, leading to higher transportation needs and increased diesel demand. Poor road conditions caused by snow and ice can slow down last-mile distribution, reducing inventory at the pump.

The change in fuel formulation during winter also contributes to higher diesel prices. To prevent diesel fuel from "gelling" at extremely low temperatures, refiners add blending agents, increasing production costs. The shift to Ultra-Low Sulfur Diesel (ULSD), which requires additional processes to remove sulfur, further raises production costs.

Overall, winter storms and extreme cold temperatures have a significant impact on diesel prices by disrupting the supply chain, increasing production costs, and affecting demand for diesel and heating oil. These factors contribute to higher diesel prices during the winter months.

How diesel prices have changed over time

The usage of distillate fuel oil began in the 1930s, but until further development in the 1960s, diesel vehicles were used mostly for commercial purposes. In the U.S., diesel-powered cars remain a small portion of the automobile market, and diesel consumption is far lower than gasoline consumption. Generally, gasoline 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, so they are used for large commercial vehicles.

The U.S. Energy Information Administration (EIA) releases gasoline and diesel fuel prices weekly. The retail prices for diesel fuel in the U.S. are measured in U.S. dollars per gallon.

The retail price of diesel fuel in the United States has fluctuated over time. For example, the price in December 2022 was different from the price in December 2024.

It is worth noting that the diesel fuel prices provided by the EIA are adjusted for inflation.

Diesel prices in high-income countries

As of 23 June 2025, the average price of diesel worldwide was 1.21 US dollars per litre. However, diesel prices vary significantly across countries. Generally, richer countries tend to have higher prices, while poorer countries and oil-producing/exporting nations tend to have lower prices. An exception to this trend is the United States, a high-income country with relatively low gas prices.

Hong Kong, a high-income economy, had one of the highest diesel prices in the world as of 11 November 2024. Drivers in Hong Kong paid an average of 3.18 US dollars per litre of automotive diesel, more than three times the amount paid by drivers in Mainland China.

In contrast, lower diesel prices are often associated with substantial domestic crude oil production and government subsidies. Examples of such countries include Venezuela, Iran, and the United States, which benefit from their domestic oil production capabilities or the availability of government subsidies to offset diesel costs.

Frequently asked questions

$3.51 per gallon.

Regular gasoline was cheaper at $3.06 per gallon.

The price surge was due to the impending impact of winter storm Blair.

Fuel prices are usually higher in high-income countries, but the US benefits from its position as the world's largest crude oil producer, so it can keep prices comparatively low.
