Diesel fuel averaged $6.331 a gallon across the United States in September, up from $3.730 a year earlier, the Bureau of Labor Statistics reported in its average retail price data. The 69.7 percent increase left diesel 78.4 cents above August’s $5.547, a one-month jump of 14.1 percent. Diesel powers long-haul trucks and farm equipment, so its price reaches shoppers through shipping costs more than through the pump. The latest weekly reading from the Energy Information Administration, $6.179 for the week of October 12, was down two cents from the week before.
For households, the question is whether the cost of moving goods reaches store shelves and delivery fees, and BLS’s September consumer price report shows no sign of it yet: the food-at-home index fell 0.1 percent for the month, and food overall is up 2.5 percent over 12 months. Energy is where the pressure shows, up 5.2 percent in September alone and 20.4 percent over the year. Households that heat with oil or pay for gasoline feel the same fuel shock directly, and several benefit programs exist to offset household energy and food costs.
Diesel’s 69.7 percent jump reaches households through freight, farms and fuel bills at the same time, and the programs that offset those costs have income limits. The Benefits Checklist covers 11 benefit programs, including heating help and SNAP, with the 2026 income limits for each.

Diesel’s September climb against gasoline
The Bureau of Labor Statistics table lists automotive diesel at $6.331 a gallon for September, against $3.730 for September 2025. In the Midwest, the average went from $3.526 to $6.198, a rise of 75.8 percent. BLS notes that its monthly figures describe the month as a whole rather than any specific date, so it does not line up with weekly surveys taken on particular days.
Gasoline rose too, but by less than half as much. All types of gasoline averaged $4.631 a gallon in September, 33.0 percent above a year earlier, while diesel gained 69.7 percent. BLS’s September inflation report says the gasoline index rose 9.1 percent in the month, accounting for over half of the monthly all-items increase of 0.6 percent.
What truckers and freight rates are signaling
The Energy Information Administration’s weekly survey put on-highway diesel at $6.179 for the week of October 12, $2.514 above a year earlier. The West Coast averaged $7.240 and California $8.091, while the Gulf Coast was lowest at $5.809. The two-cent dip from the prior week is small against the year’s gain: diesel is up at least $2.18 a gallon from a year earlier in every region the survey lists.
Heavy Duty Trucking reported that the national average hit a record $6.53 a gallon on September 22, according to AAA. Todd Spencer, president of the Owner-Operator Independent Drivers Association, said every $1 increase per gallon costs its members around $400 more per week. Dean Croke of DAT Freight & Analytics said freight rates usually take three to four weeks to catch up with rising diesel prices, and DAT’s September fuel component reached a record 84 cents a mile for a van. Higher shipping rates are the channel by which diesel could reach consumer prices.
EIA’s outlook for diesel supply into 2027
EIA’s October Short-Term Energy Outlook, released October 6, cites “extreme tightness in diesel markets.” East Coast distillate inventories, the category that includes diesel and heating oil, fell 32 percent below their five-year seasonal average in September. EIA forecasts them to stay around 20 percent below the 2021-2025 average through the winter, and to recover to near the five-year average only in the second half of 2027.
The same outlook says the squeeze reaches home heating too: the homes that burn heating oil, about 3 percent of households, face prices up more than 30 percent from last winter, and EIA expects their winter spending to rise 21 percent.
The agency expects retail diesel to average about $5.19 a gallon in 2026 and about $4.50 in 2027, both raised from the prior forecasts of $5.07 and $4.40. That is a drop of roughly 70 cents from this year to next, but it would still leave diesel well above the $3.730 of September 2025. Whether that gap reaches food and goods prices will show in coming consumer price reports, since Croke’s three-to-four-week lag applies to freight rates first.
Programs that offset fuel and food costs
The federal Low Income Home Energy Assistance Program covers heating bills, preventing shutoffs and reconnecting service, and repairing or replacing heating equipment, according to its federal page. To apply, households can use energyhelp.us or call the National Energy Assistance Referral line, 1-866-674-6327, which answers Monday through Friday from 9 a.m. to 7 p.m. Eastern. The page says the program charges no fee and lists the HHS Fraud Hotline, 1-800-447-8477, for anyone offered a grant or asked to pay.
Fuel-driven price pressure does not arrive evenly. The September report shows energy up 20.4 percent over the year while food at home slipped in the month, and the energy index had also risen 2.1 percent in August, so September’s 5.2 percent was the second straight monthly increase. That makes heating and driving costs the line items to watch first. The LIHEAP page does not list income limits and sends applicants to energyhelp.us or their local program for the requirements.
EIA’s next weekly diesel release is scheduled for October 20 and will show whether the two-cent dip becomes a trend. Its November 10 outlook will update the $4.50 forecast for 2027 against a market EIA describes as showing “extreme tightness.”
