U.S. gasoline prices decreased across all fuel grades in July 2025 when compared to the month before. Regular gasoline prices rose to an average of 3.17 U.S. dollars per gallon. In the period of consideration, gasoline prices reached their highest level in June 2022. Differences in fuel grades Fuel grades at U.S. gas stations are differentiated by octane level. Higher grade fuels have higher octane levels, meaning that the fuel can be compressed more in the engine. This enables high-performance engines to create more power. Fuel may also vary from state to state and pump to pump. Some cities also have regulations on gasoline in order to improve air quality. Bioethanol is added to gasoline in some cases to meet the renewable fuel standard. Gasoline-run engines are able to run on blends with a bioethanol percentage of up to 25 percent. Gasoline prices reach historic high Primarily a result of the Russia-Ukraine war and inflation, the annual retail price of gasoline reached a new historic high in 2022, climbing to nearly four U.S. dollars per gallon. By 2024, annual prices had decreased again slightly, reaching 2014 levels.

Gasoline prices in the United States have experienced significant fluctuations over the past three decades, with 2024 seeing an average price of 3.3 U.S. dollars per gallon. This marks a notable decrease from the record high of 3.95 U.S. dollars per gallon in 2022, yet remains considerably higher than prices seen in the early 2000s. Despite this, American consumers continue to enjoy relatively low gasoline prices compared to many other countries, with some European countries paying more than double the U.S. average. Drivers in Hawaii and California pay the most at the pump Gasoline prices vary significantly across the United States, with Hawaii and California consistently ranking as the most expensive states for this fuel. As of January 1, 2025, Hawaii's average price for regular gasoline was 4.54 U.S. dollars per gallon, nearly 1.5 dollars above the national average. California's high prices are largely attributed to its steep gasoline taxes, which reached 68.1 U.S. cents per gallon in January 2024. These taxes play a crucial role in shaping retail prices and are typically reinvested in road infrastructure, demonstrating the direct link between fuel costs and transportation development. Patterns in gasoline consumption In a global context, the United States maintains some of the lowest conventional motor fuel prices among high-income countries. This is largely due to its position as the world's largest crude oil producer, allowing it to keep retail prices comparatively low. Despite fluctuations in price, gasoline consumption in the U.S. remains robust, averaging around 8.5 million barrels per day in 2024. Consumption tends to be highest in the summer months and lowest in the winter months due to changing driving behavior.

In September 2025, one gallon of diesel cost an average of 3.75 U.S. dollars in the United States. That was an increase compared to the month prior, and higher than prices in September 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 since 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.

In the spring of 2018, a 10-day field study was conducted in Colorado’s Denver-Julesburg oil and natural gas production basin to improve information on well pad pneumatic controller (PC) populations and identify PCs with potential maintenance issues (MIs) causing excess emissions through a novel optical gas imaging (OGI) survey approach. A total of 500 natural gas-emitting PCs servicing 102 wells (4.9 PCs/well) were surveyed at 31 facilities operated by seven different companies. The PCs were characterized by their designed operational function and applications, with 83% of the PC population identified as intermittent PCs (IPCs). An OGI inspection protocol was used to investigate emissions on 447 working PCs from this set. OGI detected continuous emissions from 11.3% of observed IPCs and these were classified as experiencing some level of MIs. OGI imaging modes were observed to have a significant effect on emission detectability with high sensitivity mode detection rates being approximately 2 times higher compared to auto mode. Fourteen snapshot emission measurements (not including actuations) were conducted on IPCs in this category using a high-volume sampling device with augmented quality assurance procedures with observed emissions rates ranging from 0.1 up to 31.3 scf/hr (mean = 2.8 scf/hr). For PCs with continuous depressurization type (CPC), 36.8% had continuous emissions observed by OGI. Four supporting emission measurements were conducted on CPCs with one unit exceeding the low bleed regulatory emission threshold with an emission rate of 9.9 scf/hr (mean = 4.2 scf/hr). Additional information was collected on PC actuation events, as observed with OGI, which showed a strong correlation between observed actuation events and facility production compared to observed continuous emissions caused by MIs which did not correlate with facility production. Implications: A novel survey approach of pneumatic controllers at oil and natural gas production facilities in the Denver-Julesburg basin, using optical gas imaging and supporting emission measurements, was demonstrated as an effective method to identify controllers with potential maintenance issues causing excess emissions. The results of the pneumatic controller and optical gas imaging surveys improved information on pneumatic controller populations within the basin and also demonstrated the significant effect optical gas imaging modes have on emission detections.

An economic analysis of producing Fischer–Tropsch (FT) liquid fuel such as diesel from crop residue is presented. The process is thermochemical based involving fast pyrolysis and autothermal reforming (ATR) followed by FT synthesis. A spreadsheet for estimating economics is presented, which is simple to use and transparent in its input parameters and its output. Plant sizes of 2000, 10 000, and 35 000 dry metric tons (t) per day were calculated at 8% return on capital to require sales prices (exclusive of tax) of $3.30, $2.40, and $2.06 per gallon (gal), respectively. U.S. tax would add another ∼$0.50/gallon. A biomass feed stock cost of $61.20/dry t was assumed. Capital cost for the 2000 dry t/day plant is estimated to be $M231. These estimates, of course, must be regarded as rough, but they suggest that even without the benefit of imposed regulations liquid fuel derived from biomass could be competitive at current price levels. Sale of char produced in the pyrolysis step for soil amendment as a byproduct at $500/t, had a significantly favorable impact on the economics, reducing diesel price by $0.35/gal. Like the heavy influence of the cost of crude oil on current fuel price, the cost of biomass is the largest single contributor to the final price of biomass derived fuel and becomes more so as plant capacity increases. This suggests the need to improve methods of biomass gathering and delivery. For each $10/dry t increase in the price of biomass the sales price of the FT fuel is estimated to increase by $0.20/gal. It is estimated that pyrolyzer collectives 25 miles square (mi2) on a side would reduce diesel price by $0.12/gal, as compared to those 14 mi2 on a side.
