Gasoline Demand

U.S. gasoline demand in 2026 is expected to be 8.9 million barrels per day, approximately 370 million gallons per day, or about 37 million fill-ups per day (based on a 10-gallon fill-up). Demand peaked at a record 9.3 million barrels per day in 2018. (Source: U.S. Energy Information Administration, Short-Term Energy Outlook, January 2026)

Consumption of ethanol-blended into gasoline is expected to average 1.07 million barrels per day in 2026; the ethanol share in gasoline is expected to average 12.1%. (Source: U.S. Energy Information Administration, Short-Term Energy Outlook, January 2026)

Typically, U.S. gasoline demand increases during the first half of the year (beginning in February) and peaks in the warmer months. In 2025, that gasoline pattern largely held, with demand peaking in July and August, during peak vacation travel season. Demand in August 2025 was 743 thousand barrels/day more (8.8%) than in January 2025.

U.S. Oil Imports and Exports

The U.S. imports more petroleum products from Canada than any other country, an estimated 60-68%.  
(Source: U.S. Energy Information Administration)

Crude oil imports have been relatively low the last few years. In 2025, monthly imports of crude oil and petroleum products ranged from 2.0 to 3.9 million barrels per day. From 1994 to 2018, imports of crude oil and petroleum products were at least 7 million barrels per day and topped 10 million barrels per day several times. The United States first tracked oil imports in 1902, when it imported 2,000 barrels per day. (Source: U.S. Energy Information Administration, U.S. Imports by Country of Origin)

Strategic Petroleum Reserve

With a capacity of 714 million barrels, the U.S. Strategic Petroleum Reserve (SPR) is the largest stockpile of government-owned emergency crude oil in the world. As of January 9, 2025, the SPR had 413.7 million barrels of inventory. The SPR was established in 1975 in the aftermath of the 1973-1974 oil embargo to provide emergency crude oil supplies for the United States. The oil is stored at four sites with deep underground (Source: U.S. Department of Energy, SPR Quick Facts and FAQs)

It takes about 13 days from the time a presidential decision is made to tap the SPR for oil to enter the U.S. market. (Source: U.S. Department of Energy, SPR Quick Facts and FAQs)

Refining

Nearly 60% of U.S. refineries have closed over the past 40 years. In 1982, the earliest data provided, there were 301 operational refineries. There were 131 operating refineries in 2025. The last major refinery built in the United States was completed in 1976. (Source: U.S. Energy Information Administration, Number and Capacity of Petroleum Refineries ) 

Despite the precipitous drop in the number of refineries operating in the United States, domestic refining capacity has only slightly declined. Increases in facility size and improvements in efficiencies have offset much of the lost physical capacity of the industry. The operating capacity of U.S. refineries was a record 18.98 million barrels of crude oil per day in 2020 but has dropped to 18.42 million barrels per day in 2025. (Source: U.S. Energy Information Administration, U.S. Refinery Operable Atmospheric Crude Oil Distillation Capacity)

On average, a 42-gallon barrel of oil produces 19 to 20 gallons of gasoline, 11 to 13 gallons of distillate fuel (largely diesel), 3 to 4 gallons of jet fuel and 6 gallons of other refined product as part of the refining process in U.S. refineries. The total of refined product is more than the input because of refinery processing gain. (Source: U.S. Energy Information Administration, Refining Crude Oil)

The Marathon Petroleum refinery in Galveston Bay, Texas, has a capacity of 631,000 barrels of crude oil per day, making it the largest refinery in the United States and one of the 10 largest in the world. Six U.S. refineries have operable capacities of at least 500,000 barrels per day. (Source: U.S. Energy Information Administration)

Planned periodic shutdowns of refineries, called turnarounds, allow for the regular maintenance, overhaul, repair, inspection and testing of plants and their process materials and equipment. They are scheduled up to 10 years in advance and usually when demand for refined product is at its lowest level, typically early in the year. The industry average is about four years between turnarounds. During this time, refineries also may optimize their operations so that they can refine summer-blend fuel.

Refined Product Tankers

General purpose tankers are often used to transport refined product on shorter trips, such as between North America and Europe. They can transport 70,000 to 190,000 barrels per tanker. Crude oil from the Middle East is moved mainly by Very Large Crude Carriers capable of delivering 2 million barrels per trip. A small number of Ultra-Large Crude Carriers can deliver as much as 3.7 million barrels of crude oil. By comparison, a train of 100 cars can transport 3 million gallons, and a truck typically holds 9,000 gallons. (Source: U.S. Energy Information Administration)

More than 20% of all oil is transported through the Strait of Hormuz, which links Middle East crude producers to markets in Asia Pacific, Europe and North America. (Source: U.S. Energy Information Administration, The Strait of Hormuz is the World’s Most Important Chokepoint)

Fuel Pipelines  

Overall, 83% of crude oil and refined products are transported by pipeline, with 9% transported by rail and 8% transported by water carrier; 92% of crude oil is transported by pipeline. (Source:  Bureau of Transportation Statistics )

The first oil pipeline in the United States was built in 1865, following the 1859 discovery of oil in Pennsylvania. Today, pipelines are the most important petroleum supply line in the U.S. for transporting crude oil, refined fuel and raw materials. Pipeline transport crude oil and more than 50 refined petroleum products, including various grades of gasoline, home heating oil, diesel fuel, jet fuel and kerosene. (Source: Pipeline 101, The History of Pipelines)

The diameter of pipelines varies greatly. For cross-country crude oil transport, diameters are typically 8 to 24 inches but are as large as 48 inches for the Trans-Alaska Pipeline System. Pipelines for refined products range in size from 8 to 42 inches. (Source: Pipeline 101, How Do Pipelines Work?)

There are 229,888 miles of U.S. oil, refined products and natural gas liquids pipeline. This includes over 80,000 miles of crude oil pipelines, 70,000 natural gas liquids pipeline miles and 62,000 miles of petroleum products pipeline. (Source: Pipeline 101: Where Are Pipelines Located? )

The Colonial Pipeline is the country’s largest pipeline system, spanning 5,500 miles from Houston, Texas, to New York Harbor (Linden, New Jersey) and transporting more than 100 million gallons of fuel daily. (Source: Colonial Pipeline Company)

Crude oil moves through pipelines at about 3 to 8 miles per hour (about a walking pace), but other products can move through faster depending upon line size, pressure and other factors such as the density and viscosity of the liquid being transported. For example, natural gas can travel as fast as 25 miles per hour. On average, it takes from 14 to 22 days to move liquids from Houston to New York City. (Source: How Pipelines Make the Oil Market Work — Their Networks, Operation and Regulation)

Ethanol transportation by pipeline is not widespread; it is generally blended at the local wholesale terminal for use as E10 or E85. Because ethanol has an affinity for water and is a better solvent than gasoline, it is more likely to bind to any water in pipelines or pick up impurities. In addition, gasoline pipelines generally start in the South, near petroleum refineries. Because most ethanol is produced in the Midwest, the current pipeline system is not conducive to transporting the alternative fuel. (Source: U.S. Department of Transportation)

Rail Transport

The freight rail network is nearly 140,000 miles. The amount of crude oil transported by rail carload varies by the source of the oil, the type of tank car used and the season of the year. In 2023, the average carload of crude oil originated in the United States carried 650 barrels of oil. The 97,000 carloads of crude oil originated by U.S. Class I railroads in 2023 was equivalent to around 173,000 barrels per day, or approximately 1.3% of total U.S. production. (Source: Association of American Railroads)

As much as 70% of ethanol product in the United States moves throughout the country by rail. Most ethanol carried by railroads moves in 30,000-gallon tank cars. (Source: Association of American Railroads, Freight Rail and Energy)

Brent crude oil spot prices averaged $69.04 per barrel in 2025. West Texas Intermediate (WTI) crude oil spot prices averaged $65.40 per barrel in 2025. (Source: U.S. Energy Information Administration, Short-Term Energy Outlook, January 2026)

With 42 gallons in each barrel of oil, a $1 change in the price of a barrel of oil roughly translates to a 2.4-cent change per gallon at the pump.

This last category includes all post-refinery expenses and retailer profit. (Source: U.S. Energy Information Administration, Gasoline Pump Components History, Jan.-Dec. 2025)

Price volatility has been extreme over the past two decades. Daily crude oil prices fluctuated between a low of $18.28 in November 2001 to a high of $147.27 per barrel in July 2008. (WTI oil futures briefly dipped to -$37 per barrel in April 2020.) Daily national average gasoline prices fluctuated between a low of $1.06 in December 2001 to a high of $5.02 in June 2022. The highest diesel fuel price recorded was $5.82, also in June 2022. The highest average price in a state is $6.44 for gasoline and $7.01 for diesel fuel, both in California in June 2022.

Since the final implementation of the Clean Air Act Amendments in 2000, the seasonal transition to summer-blend fuel has caused gasoline prices to rise significantly before reaching their peak, with increases ranging from a low of 1 cent in 2020 to a high of $1.56 per gallon in 2022. The average annual increase over the past 26 years is 50 cents per gallon.

Gasoline theft, also called drive-offs, is a problem at stores that don’t require prepay. The average loss per store in 2016 was $888 per store reporting theft. It is difficult to obtain an industrywide number because only a small percentage of stores today allow customers to pump their fuel before paying. Gasoline theft peaked in 2005 when it cost the industry an estimated $300 million. It had declined considerably since September 2005 (post-Hurricane Katrina when gasoline rapidly increased and topped $3 per gallon) as more stations began mandating prepay. However, new forms of theft involving high-tech fuel dispenser manipulation have emerged over the past few years. (Source: NACS State of the Industry data)

Over the past five years, retailer gross margins (before expenses) have averaged 38.3 cents per gallon. Retailer expenses to sell fuel are about 20-25 cents, with about 8 cents/gal as credit card fees. Distribution of fuel usually costs about 8 cents/gal, but that increases when diesel prices increase and were around 12 cents/gal when gas prices topped $4.50 in 2026.

Barrel: The unit of measure for petroleum products. A barrel holds 42 gallons and futures contracts are in 1,000-barrel lots. According to Daniel Yergin, the standard of a 42-gallon barrel dates to the year 1482, when King Edward issued a statute that 42 gallons was the standard for a barrel of herring.

Boutique Fuels: Unique gasoline blends required for a specific region or metropolitan area of the U.S. Prior to 1990, six types of gasoline were sold in the United States, and that grew to as many as 14 in the late 2010s. Today, there are 10 unique gasoline formulations, not including regular/mid-grade and premium octanes for each fuel, manufactured for and sold within specific markets throughout the country that are mandated by federal, state, and local governments. These fuels are not interchangeable with fuel blends sold in other areas of the country.

Branded Retail Outlet: A retailer that sells motor fuels with the brand name of a major oil company or refiner but is not necessarily owned (and is usually not owned) by that company. Branded retailers benefit from marketing and advertising support, consumer brand loyalty and priority access to gasoline supplies. Lately, a new benefit has emerged, with branded stations participating in loyalty programs with grocery chains. In return, the branded marketer pays a surcharge for the use of the brand and the benefits that come with it.

Contango: When crude oil market near-term prices are lower than longer-dated ones, such as in April and May 2020 when futures were negative. The opposite is “backward-dated”, which is when near-term prices are higher than longer-dated ones.

Ethanol-Blended Fuels (E10, E15, E85, etc.): E10 (90% gasoline and 10% ethanol) is approved for use in all new U.S. automobiles. Higher blends of ethanol (known as “flex fuels”) can be used in flex-fuel vehicles and under some other conditions. E15 is 85% gasoline and 15% ethanol and is approved by the U.S. Environmental Protection Agency for use only in vehicles manufactured in 2001 or later, but not in older vehicles, motorcycles, watercraft or small engines. E85 is not 85% ethanol; it is a mixture of gasoline with ethanol content between 51% to 83%.

Fuel Retailer: As of December 2025, 122,620 convenience stores sold gasoline and other fuels in the United States, representing 80.7% of country’s 151,975 convenience stores. These retailers are also referred to as “petroleum marketers.”

Fungible: Interchangeable. The U.S. gasoline system was designed to facilitate the efficient flow of gasoline to all regions of the nation, allowing the same gasoline formulation to be sold in all markets. The system is no longer fungible, with 10 unique gasoline formulations required in specific markets throughout the United States.

Futures: Crude oil futures have been traded on NYMEX since 1983 and are now the most heavily traded commodity. Futures trade in units of 1,000 U.S. barrels (42,000 gallons).
Trading terminates at the close of business on the third business day prior to the 25th calendar day of the month preceding the delivery month.

On-Demand Fueling (or Mobile Fueling): When fuel is delivered directly to fleets and individual consumers with pay-as-you-go, member- and subscription-based business models. The first wave of companies pioneering the concept in the 2010s largely replaced by new startups in the 2020s.

Organization of Petroleum Exporting Countries (OPEC): OPEC an international organization of 12 countries that are heavily reliant on oil revenues as their main source of income: Algeria, Congo, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia, United Arab Emirates and Venezuela. These countries collectively supply about 32% of the world’s crude oil and liquid fuels output and possess nearly 80% of the world’s total proven crude oil reserves. Twice a year, or more frequently if required, the oil and energy ministers of OPEC member countries meet to decide on its output level and consider whether any action to adjust output is necessary because of recent and anticipated oil market developments.

OPEC+: The 12 oil producing countries that are part of OPEC plus 11 other oil-producing countries—among them Russia, Kazakhstan and Mexico—that have also agreed to work together to regulate supply and help dictate oil prices. Collectively, they control approximately 41% of total supply and 90% of proven reserves.

Pass-Through: The time from which wholesale price changes fully reach consumers. Wholesale gasoline price increases—or decreases—paid by retailers are not immediately passed on to consumers but are spread over a period. A large portion of the price change is passed through immediately, with the rest spread over a period that could be eight weeks. Pass-throughs help minimize the price volatility of gasoline.

Petroleum Administration for Defense Districts (PADD): The U.S. Department of Energy divides the United States into five regions for planning purposes. The result is a geographic aggregation of the 50 states and the District of Columbia into five districts, each operating essentially as its own market. The five districts are: PADD I (East Coast), PADD II (Midwest), PADD III (Gulf Coast), PADD IV (Rocky Mountain) and PADD V (West Coast).

Refinery: Where crude oil is refined into a specific blend of gasoline or other fuels (such as diesel, kerosene, etc.) or for other oil-based applications. There are currently 131 operating refineries in the United States—less than half the number from 1981. No major new refinery has been built in the United States since 1976.

Reformulated Gasoline (RFG): The 1990 Clean Air Act Amendments required the most polluted metropolitan areas in the United States to sell a special blend of gasoline to reduce the emissions of ozone forming volatile organic compounds (VOCs) and toxic air pollutants. The first phase of the RFG program began in 1995, and the second (current) phase began in 2000. RFG is required in cities with high smog levels and is optional elsewhere. RFG is currently used in 17 states and the District of Columbia. Approximately 25% of gasoline sold in the U.S. is reformulated.

Replacement Costs: The cost to acquire the next shipment of fuel. This price is almost always different than the cost of the gas that retailers have in their tanks. Because of the enormous volume of fuel sold (an average store sells 3,00-4,000 gallons of gas a day), retailers must price their fuel based on their estimated cost of the next delivery. Even slight wholesale price variations can increase a retailer’s replacement cost by hundreds or even thousands of dollars. The importance of replacement costs is particularly acute for smaller businesses, which have less cash on hand to meet payments.

Spot Market: This market is usually comprised of motor fuels that have not been pre-allocated to the integrated or branded outlets. Retailers and other fuel distributors purchase fuel at terminals, or “racks,” where costs fluctuate based on current prices.

Summer-Fuel Blends: Several state and local governments have developed fuel regulations to control for the formation of smog during summer months. These generally require that gasoline sold during the summer have a lower Reid vapor pressure (RVP), which measures the gasoline’s potential to emit vapors and can contribute to the formation of smog.

Terminal: A bulk gasoline terminal is a gasoline storage facility that receives gasoline by pipeline, ship or barge, and has a gasoline throughput greater than 20,000 barrels per day. The loading rack at the terminal is the broad term for the loading arms, pumps, meters, shutoff valves, relief valves and other piping and valves that fill delivery tank trucks picking up product at the terminal.

Tight Supplies: Describes a situation in which demand for gasoline or crude oil exceeds the supply available, and prices rise based on this supply/demand imbalance. Also known as “market shorts” or “upsets.”

Ultra Low Sulfur Diesel (ULSD): ULSD is a clean-burning diesel fuel that is defined by the United States Environmental Protection Agency (EPA) to have a maximum sulfur content of 15 parts per million (ppm). It was phased into use between 2006 and 2010.
