This is the result of crude oil transportation disruptions combined with reduced refinery output. Because diesel production is difficult to increase quickly, transportation and food prices also face upward pressure.\n\nThe price figures are based on AAA's September 21, 2026 tally and EIA's September 14 survey.\n\n## How Much Have U.S. Diesel Prices Risen?\n\nThe U.S. average diesel price tallied by AAA is $6.5107 per gallon. The reference date is September 21, 2026. The price has already passed the point where breaking $6.5 per gallon can be described only as a future possibility. [AAA fuel prices](https://gasprices.aaa.com/)\n\nThe U.S. Energy Information Administration, or EIA, publishes separate weekly prices. Its surveyed price on September 14, 2026 was $6.285 per gallon. Because AAA and EIA use different survey timings and methods, their figures must be distinguished.\n\n| Reporting organization and reference date | Diesel | Regular gasoline | Price basis |\n| --- | ---: | ---: | --- |\n| AAA, September 21, 2026 | $6.5107 per gallon | $4.4786 per gallon | U.S. national average retail price |\n| EIA, September 14, 2026 | $6.285 per gallon | $4.319 per gallon | U.S. national average, including taxes |\n\nThe EIA diesel price rose by $0.318 per gallon from the previous week. Regular gasoline rose by $0.162 per gallon over the same period. Diesel was not the only fuel that increased, but its increase was larger during this period. [EIA weekly fuel prices](https://www.eia.gov/petroleum/gasdiesel/)\n\n## Why Is Diesel Rising More When It Comes From the Same Crude Oil?\n\nDiesel and gasoline prices vary according to their respective supply and demand. Crude oil is the raw material used to make both products. When finished fuels are in short supply, product prices can rise faster than crude oil prices.\n\nDiesel is used as fuel for trucks, agricultural machinery, and other equipment. Diesel and similar petroleum products are collectively called middle distillates. EIA's distillate statistics also include heating oil. The diesel market is therefore affected not only by freight transportation but also by heating demand. [EIA factors affecting diesel prices](https://www.eia.gov/energyexplained/diesel-fuel/factors-affecting-diesel-prices.php)\n\n| Category | Gasoline | Diesel and related distillates |\n| --- | --- | --- |\n| Typical demand | Passenger vehicle use | Freight transportation, agriculture, industrial activity |\n| Seasonal demand factor | Summer automobile travel | Fall harvest, winter heating |\n| Indicator of a supply shortage | Gasoline production and inventories | Diesel and heating oil production and inventories |\n| Relative scale of U.S. consumption | Most-consumed petroleum product | Distillate fuel ranks second |\n\nIt is incorrect to say that U.S. diesel consumption is higher than gasoline consumption. EIA describes gasoline as the most-consumed petroleum product in the United States. The current price difference should be understood in terms of product-specific supply shortages rather than consumption rankings. [EIA explanation of petroleum product consumption](https://www.eia.gov/finance/markets/products/consumption.php)\n\n## Can Refineries Simply Make More Diesel?\n\nRefineries can increase the share of diesel they produce, but there are limits. Refining crude oil produces several products together, including gasoline and diesel. The production mix is affected by the properties of the crude oil and the configuration of the refining equipment.\n\nIt is therefore also inaccurate to say that the production ratio is always fixed. Conversely, refineries cannot freely increase diesel alone while leaving their equipment unchanged. The petroleum industry group API also explains that there are limits to adjusting the product mix. [API analysis of diesel supply](https://www.api.org/news-policy-and-issues/news/2026/08/26/inside-the-global-squeeze-on-diesel)\n\nThe difference between the diesel price and the crude oil price is called the diesel crack spread. It is the price difference between the product and the raw material when compared on the same volume basis. It is an indicator of refining profitability, but it is not the same as a refiner's net profit. [EIA explanation of price differences](https://www.eia.gov/finance/markets/products/consumption.php)\n\n- Recovery in crude oil supply: More raw material available to refineries\n- Recovery in refinery operations: More fuel produced for actual sale\n- Recovery in product transportation: More supply available for regions facing shortages\n\nThese are recoveries at different stages, so increasing crude oil supply alone will not resolve every problem.\n\n## How Do the Saudi Pipeline and Russian Refineries Affect the Market?\n\nDisruptions to the Saudi pipeline limit transportation routes that avoid the Strait of Hormuz. The East-West Pipeline carries crude oil from eastern Saudi Arabia to the Red Sea port of Yanbu. If this route is blocked, it puts pressure on crude oil exports and the procurement of feedstock for refineries.\n\nKpler analyzed supply disruptions in the Yanbu area on September 17, 2026. The analysis also pointed to losses in diesel production at Yasref. This is why the pipeline problem cannot be interpreted solely as a decline in crude oil exports. [Kpler analysis of the Yanbu supply disruption](https://www.kpler.com/blog/yanbu-pipeline-attack-ripples-across-crude-freight-and-gas-markets)\n\nReduced operations at Russian refineries are another factor putting pressure on diesel supply. EIA's September 2026 outlook describes this as a factor raising international distillate prices. Disruptions in the Middle East and Russia are having an effect at the same time. [EIA September 2026 Short-Term Energy Outlook](https://www.eia.gov/outlooks/steo/archives/sep26.pdf)\n\nAccording to AP, President Trump called for Ukraine to stop its attacks on September 13. He claimed that attacks on Russian diesel-related facilities were causing fuel shortages. This statement alone does not rule out the impact of the war in the Middle East. [AP report on the remarks](https://apnews.com/article/russia-ukraine-war-drones-odesa-refinery-border-crossing-17bb6a0401abc3eaa7d4586150a41d7d)\n\n## Why Are Tanker Freight Rates Rising as Well?\n\nUsing dangerous shipping routes or taking detours increases transportation costs. When ships remain tied up for longer, their capacity to transport other cargo also decreases. Route risks also affect marine insurance costs.\n\nWindward summarized freight rates by route on September 17, 2026. Spot charter rates for very large crude carriers passing through Hormuz had surged. Charter rates are the price of renting a vessel and are a different indicator from retail fuel prices.\n\n| Route presented by Windward | Charter rate level | Conditions to consider when interpreting |\n| --- | ---: | --- |\n| Loading crude oil inside the Persian Gulf after passing through Hormuz | Assessed on September 11, 2026 at more than $1 million per day | Specific very large crude carrier spot market |\n| Shipping from Oman to China | About $600,000 per day in the September 17, 2026 report | Route that does not pass through Hormuz |\n\nThese figures should not be applied as the average freight rate for all tankers. Detours by some Saudi vessels tracked by Windward added 10 to 14 days. It is also inaccurate to say that every detoured shipment takes an additional month. [Windward maritime transportation analysis](https://windward.ai/blog/houthis-take-perim-and-petroline-is-hit-as-freight-rates-soar/)\n\n## What Does the Panama Canal Drought Change?\n\nWater shortages in the Panama Canal restrict vessel reservations and loading conditions. The canal raises and lowers ships by changing the water level inside its locks. When there is not enough fresh water for this process, transit capacity decreases.\n\nThe Panama Canal Authority issued notice A-29-2026 on August 20, 2026. The notice announced reservation reductions because of lower rainfall and insufficient water inflows. The figures below are the number of reservable slots specified in the notice, not actual transit figures.\n\n| Item | Figure in the official notice | Applicable period |\n| --- | --- | --- |\n| Cumulative watershed rainfall | 34% below the long-term average | May to August 2026 |\n| Watershed inflows | 44% below the long-term average for the same period | May to August 2026 |\n| Daily reservable slots | 34 vessels in total | Effective September 4, 2026 |\n| Daily reservable slots | 32 vessels in total | Effective September 15, 2026 |\n\n\u003e the number of daily slots available at the Panamax Locks will be adjusted to twenty-three (23).\n\u003e\n\u003e Panama Canal Authority, Advisory to Shipping No. A-29-2026\n\nThe quotation states that reservations for the original locks will be adjusted to 23 vessels per day. Adding the 9 daily slots at the expanded locks brings the total to 32 vessels. Actual operating conditions should be checked in subsequent notices from the canal authority. (Verified value: 32 total reservable slots/day, 23 Panamax and 9 Neopanamax · Source: pancanal.com · Checked 2026-09-15) [Panama Canal Authority A-29-2026](https://pancanal.com/wp-content/uploads/2026/08/ADV-29-2026-Additional-Measures-to-Address-Reduced-Precipitation-in-the-Canal-Watershed.pdf)\n\nIf reservation auctions become more expensive, transportation costs for the affected vessels may increase. However, the rate of increase in auction prices is different from the rate of increase in overall tolls. The price of a specific auction cannot be generalized as the cost for all cargo.\n\nExport routes to Asia for U.S. LNG cargoes are affected. Describing the canal as a route for LNG imported by the United States does not match this flow. Canal restrictions can increase transportation burdens through detours and arrival delays. [EIA analysis of global energy transit chokepoints](https://www.eia.gov/international/content/analysis/special_topics/World_Oil_Transit_Chokepoints/)\n\n## Why Are Domestic Prices Rising While the United States Exports Diesel?\n\nDiesel-exporting countries are also affected by global product shortages. When overseas prices rise, the incentive to export U.S. diesel increases. High domestic production alone does not mean domestic inventories are sufficient.\n\nEIA's September 2026 outlook describes high net exports of distillates. Its analysis says reduced supply from the Middle East and other regions increased demand for U.S. products. EIA cited low domestic distillate inventories as a factor raising diesel prices. [EIA Short-Term Energy Outlook](https://www.eia.gov/outlooks/steo/archives/sep26.pdf)\n\nThe conditions for price recovery also involve several stages. Restarting pipelines improves the movement of raw materials. Recovery in refinery production and product inventories must be confirmed separately.\n\n| Change by condition | Meaning when assessing price pressure |\n| --- | --- |\n| Pipeline repairs only | Potential improvement in crude oil transportation |\n| Refinery production also recovers | Potential increase in diesel supply |\n| Transportation normalizes and inventories build | Potential easing of regional shortages |\n| Harvest and heating demand increases | Potential partial offset of the effects of supply recovery |\n\n## How Does This Affect Agriculture and Consumer Prices?\n\nHigher diesel prices affect consumer prices through production and delivery costs. Farms face higher fuel costs for tractors, combines, and other equipment. In freight transportation, the cost of moving goods rises.\n\nAP reported on September 11, 2026 about the burden on U.S. farms during harvest season. Fuel costs have risen during the corn and soybean harvest. However, claims that all agricultural machinery uses diesel should be avoided. [AP report on farm fuel costs](https://apnews.com/article/c320c9811a74654888255a4b4aff3d06)\n\n- Agriculture: Higher costs for diesel-powered harvesting equipment and agricultural product transportation\n- Logistics: Fuel cost burden for truck operations and deliveries\n- Food distribution: Cost burden from frequent transportation and restocking of fresh food\n- Consumers: Indirect effects through delivery surcharges or retail prices\n\nFresh food is exposed to cost pressure because it requires repeated transportation. Some companies are passing on costs through delivery surcharges. However, the timing of cost pass-through varies by product. [AP report on transportation and consumer costs](https://apnews.com/article/636252b3b82326b41661ee5c4073dacb)\n\nFood prices do not rise by the same percentage as diesel prices. Fuel costs are only one component of final retail prices. The effect varies depending on contract terms and how much of the cost companies absorb.\n\n## Common Mistakes When Reading Price Articles\n\nTo compare prices, the reporting organization and reference date must match. National averages must also be distinguished from prices at specific gas stations. The rate of increase changes when the comparison start date changes.\n\n| Common interpretation | Standard to check |\n| --- | --- |\n| $6.5 is a price that will be reached in the future | AAA's September 21, 2026 average was already $6.5107 per gallon |\n| The difference between AAA and EIA prices is an error | Differences in daily and weekly tallies and survey methods |\n| Lower crude oil prices mean an immediate drop in diesel prices | Whether refinery, product inventory, and transportation disruptions have been resolved |\n| The diesel production ratio is completely fixed | Refiners' range of adjustment and equipment constraints |\n| 32 canal reservation slots mean 32 vessels actually transited | Difference between reservable slots and actual vessel traffic |\n| Predicting Korean gas station prices from U.S. diesel prices | Differences in international product prices, exchange rates, taxes, and distribution conditions |\n\nSimply converting dollar-denominated prices into won cannot predict domestic prices. Domestic retail prices include separate costs and taxes. International diesel prices are one of several factors used to assess domestic prices.","content_html":"\u003cp\u003eThe U.S. diesel price is $6.5107 per gallon.

Therefore, describing a move above $6.5 only as a future prospect would not match the timing."},{"question":"Why do AAA and EIA report different diesel prices?","answer":"Because their survey timing and calculation methods differ. AAA's daily price and EIA's weekly survey figure should be shown together with the agency name and reference date."},{"question":"Is more diesel consumed than gasoline in the U.S.?","answer":"No. According to EIA, gasoline is the most widely consumed petroleum product in the U.S. The sharp rise in diesel prices should be explained by product-specific supply and inventory shortages rather than consumption rankings."},{"question":"Can refiners increase only diesel production?","answer":"They can adjust the production share of each product. However, there are limits based on the characteristics of the crude oil and the refining facilities. It is difficult to immediately increase only diesel production by as much as desired."},{"question":"Is the diesel refining margin a refiner's net profit?","answer":"The diesel crack spread is the price difference between equal volumes of diesel and crude oil. It differs from net profit after deducting all costs, including refinery operating costs."},{"question":"Will diesel prices fall immediately once the Saudi pipeline is restored?","answer":"It cannot be concluded that they will fall immediately. Even if crude oil flows recover, constraints may remain on refinery operations and product transportation. A recovery in diesel inventories must also be confirmed separately."},{"question":"Does the tanker rate of $1 million per day apply to all vessels?","answer":"No. The figure provided by Windward is the spot charter rate for a very large crude carrier on a specific route. It cannot be used as the average price for all tankers or long-term contracts."},{"question":"Can only 32 vessels pass through the Panama Canal each day?","answer":"Notice A-29-2026 adjusted the total number of reservation slots available per day to 32 vessels starting September 15, 2026. This is a reservation figure that must be distinguished from the actual number of vessels transiting the canal. Operating conditions should be checked in subsequent notices from the canal authority."},{"question":"How is the Panama Canal related to U.S. LNG?","answer":"It is used as a shipping route for LNG exported from the U.S. to Asia. Transit restrictions can cause diversions and delays in arrival. Diesel and LNG are different fuels, but both can be affected by transportation disruptions."},{"question":"Am I affected even if I do not have a diesel-powered vehicle?","answer":"You may be affected indirectly through the cost of transporting food and goods. However, the rate of increase in diesel prices does not translate directly into the same increase in delivery costs or food prices."},{"question":"Why are domestic prices rising even though the U.S. exports diesel?","answer":"When overseas supplies are scarce, the incentive to export U.S. diesel increases. International price increases and declines in domestic inventories can occur at the same time. It is difficult to assess the availability of domestic supply based on production volume alone."}],"sources":[{"url":"https://gasprices.aaa.com/","title":"AAA Fuel Prices: U.S. Average Fuel Prices on
