Diesel prices in Hawaii
As of November 2022, Hawaii had the fifth-highest average diesel fuel prices in the United States at $6.07 per gallon. This price is significantly higher than the average diesel price in the United States for December 2024, which was $3.49 per gallon.
While Hawaii's diesel prices are relatively high compared to other states, there can be variations within the state. For example, diesel prices in different cities in Hawaii, such as Pearl City, may differ slightly. Additionally, diesel prices can fluctuate over time.
According to GlobalPetrolPrices.com, the average diesel price in Hawaii from December 9, 2024, to March 17, 2025, was $1.42 per liter, with a minimum of $1.42 on December 16, 2024, and a maximum of $1.43 on December 9, 2024. This data is obtained from official government sources, regulatory agencies, petroleum companies, and major media sources.
It's important to note that diesel prices can vary daily and are influenced by various factors, including the cost of crude oil, supply restrictions, and demand outlooks. These factors can cause fluctuations in diesel prices not only in Hawaii but across the United States.
To find the most up-to-date diesel prices in Hawaii, it is recommended to refer to local gas station price boards or utilize real-time price-tracking websites or applications. These sources can provide you with the most accurate and current diesel fuel prices for your specific location within Hawaii.

California diesel prices
California had the highest average diesel prices in the United States as of November 2022, at $6.28 per gallon. This is in contrast to the average price of diesel across the US in December 2024, which was $3.49 per gallon.
Diesel prices are largely determined by the cost of crude oil, which regularly accounts for around 50% of the end consumer price of diesel. When crude oil prices fall, diesel prices tend to follow suit. This was the case in the latter half of 2024, when diesel prices fell to their lowest level in 24 months.
However, despite these nationwide trends, California's diesel prices have remained high compared to other states. This may be due to a variety of factors, including local taxes, transportation costs, and the unique blend of diesel fuel required in California.
California has some of the strictest emissions standards in the country, which means that the diesel fuel sold in the state must meet specific requirements. This specialized fuel blend, known as "California Diesel," can be more expensive to produce and distribute, which may contribute to the higher prices seen at the pump.
In addition, California has a relatively high tax rate on diesel fuel, which can further increase the price. The state's diesel excise tax is currently $0.375 per gallon, which is higher than the national average of $0.244 per gallon. This tax rate is regularly adjusted to fund transportation projects and infrastructure improvements in the state.

In December 2024, the average price of one gallon of diesel in the United States was $3.49, which was a slight decrease from the previous month and the lowest price in the previous 24 months. Diesel prices are largely determined by the cost of crude oil, which typically accounts for about 50% of the end consumer price of diesel.

Diesel prices in the Midwest
The price of diesel fuel is influenced by the cost of crude oil, which regularly accounts for around 50% of end consumer prices. Other factors that influence diesel prices include supply restrictions and weak demand outlooks. Diesel prices also affect the prices of many other products since most trucks and airplanes use diesel fuel for transportation. As a result, when diesel prices increase, the prices of goods like groceries, household items, and clothing also tend to rise.
In the Midwest, the retail price of diesel fuel has been a topic of interest, with sources indicating that natural gas spot prices have fallen even as international prices rose in the week ending June 11. While specific data for the Midwest region is not readily available, it is worth noting that diesel fuel prices can vary across different states.
As of November 2022, the states with the highest average diesel fuel prices included California ($6.28), Pennsylvania ($6.16), Vermont ($6.16), Connecticut ($6.12), Hawaii ($6.07), Rhode Island ($6.03), Maine ($6.00), New York ($5.98), New Jersey ($5.97), and Delaware ($5.95). These prices reflect the average costs at the time and may not represent the most recent figures.
It is worth noting that gas prices fluctuate daily, and the current average prices may differ from the posted prices. However, the relative differences in average prices across states are expected to remain relatively consistent. To track the most up-to-date average gas prices by state, organizations like the American Automobile Association (AAA) provide valuable resources for consumers.

Diesel prices in the Great Plains
The Great Plains region, particularly North Dakota, has been facing a diesel fuel supply shortage. As of late May and early June, the North Dakota Petroleum Marketers and Suppliers (NDPMA) struggled to meet demand due to scheduled maintenance in up to eight refineries in the region. This shortage has been likened to the oil embargoes of the 1970s, highlighting its severity. The NDPMA has been working with Governor Hoeven's office to secure an Hours of Service waiver to facilitate the procurement and transportation of diesel fuel into North Dakota from other states.
The Upper Great Plains region relies primarily on refineries and pipelines connected to the northern tier of the pipeline system to meet its diesel fuel demand. While the pipeline system and petroleum distribution terminals in Fargo and Grand Forks are mechanically sound, they have experienced short-term outages due to a lack of supply. The region can also source diesel fuel from refineries in Texas, Oklahoma, and Kansas; however, this has proven insufficient to meet the demand.
The diesel fuel supply shortage in the Upper Great Plains has impacted both the transportation industry and consumers. Diesel-powered trucks and airplanes play a pivotal role in transporting goods, and a shortage of diesel fuel can lead to increased prices for everyday items like groceries and clothing. The situation has been challenging for petroleum marketers and suppliers, and they have been working to minimize product outages by managing inventory and sourcing from alternative origins when possible.
While the Great Plains region grapples with diesel fuel supply issues, the average diesel price in the United States tends to be higher in Western and North-Eastern states, with Hawaii, California, and Washington topping the list. In contrast, prices are generally lower in Southern states, with Texas and Oklahoma offering more affordable diesel fuel.
