Prices readers report from the pump: what they paid, where, and how they paid. Each one is a single fill on the date shown, not a survey average; the weekly EIA figures elsewhere on this page are the survey. The middle of the prices reported here is $6.42.

What did you pay for diesel?

Tell us the price at your last fill and see how it compares with the government survey for your state. Your report goes on this site as a dated reader report; we publish your state and the first three digits of your ZIP, nothing else.

Truck-Stop Chains and Fleet-Card Discounts

Network scale and published fleet-card terms. There is no audited per-chain cash price to publish here: EIA surveys the retail market as a whole, not individual chains.

We do not publish a current cash price per chain. EIA surveys the retail market as a whole rather than individual chains, so no audited chain figure exists, and an unverified estimate sitting next to the $6.35 survey average would read as though it came from the same place. Discounts above are Comdata's and Love's Financial's published small-fleet terms, checked 27 October 2026. Check the chain app for a live local price. Full comparison ->

Why Diesel Costs $6.35/Gal Right Now

Diesel ran $2.08/gal above regular gasoline ($4.27) in the EIA survey week of October 26, 2026. In 2026 to date the gap has averaged $1.24/gal, the widest annual average in EIA's retail series back to 1995. Three causes, from EIA's own price breakdown and the tax code:

  • 1.
    Refining and distribution take a bigger cut. In EIA's May 2026 breakdown, refining was 25% of the diesel price against 22% for gasoline, and distribution and marketing 23% against 15%. The NY Harbor diesel margin over Brent crude was $2.24/gal in September 2026, against $0.75 averaged over 2021 to 2025 (our arithmetic on EIA spot prices).
  • 2.
    Heating oil and diesel are practically the same fuel. EIA notes that fall and winter heating demand puts pressure on the diesel market, and that overseas demand for distillate, where diesel cars and distillate-fired power are more common, also affects US diesel prices.
  • 3.
    Higher fuel tax. The federal excise is 24.4 cents a gallon on diesel against 18.4 cents on gasoline, and some states widen the gap: Pennsylvania charges 74.1 cents on undyed diesel against 57.6 cents on gasoline in 2026.

Frequently Asked Questions

What is the current price of diesel per gallon in the US?+
In the EIA survey week of October 26, 2026, the US national average on-highway diesel price was $6.352 per gallon (series EMD_EPD2D_PTE_NUS_DPG). That is the retail price at the pump including all federal and state taxes. The previous survey week read $6.276. Over the last nine published weeks the series ran: $5.599 on 2026-08-31, $5.967 on 2026-09-07, $6.285 on 2026-09-14, $6.529 on 2026-09-21, $6.382 on 2026-09-28, $6.199 on 2026-10-05, $6.179 on 2026-10-12, $6.276 on 2026-10-19, $6.352 on 2026-10-26.
Which state has the cheapest diesel fuel?+
The EIA weekly on-highway diesel survey does not answer that question, and this site will not pretend it does. EIA publishes a weekly diesel price for the United States, its five PADDs, three PADD 1 sub-districts, West Coast less California, and California. It publishes nothing for the other 49 states, so no federal state-by-state ranking exists. What the data does support is a district ranking: the cheapest EIA diesel district in the week of October 26, 2026 was Lower Atlantic (PADD 1C) at $5.890 and the most expensive was West Coast (PADD 5) at $7.329. State diesel excise rates, which are set in statute and do vary state by state, run from 8 cents in Alaska to 102 cents in California.
Why is diesel more expensive than gasoline?+
In the week of October 26, 2026, diesel ran $2.083/gal above regular gasoline ($6.352 against $4.269, both US national figures from the same EIA survey). In EIA's own breakdown for May 2026, crude oil was about the same cost per gallon in both fuels; the gap sat in refining (25% of the diesel price against 22% of gasoline's) and in distribution and marketing (23% against 15%). Heating oil is practically the same fuel, so winter and overseas distillate demand pull on diesel, and the federal excise is 24.4 cents a gallon against 18.4 for gasoline. In 2026 to date the gap has averaged $1.24/gal, the widest annual average in EIA's retail series back to 1995. The full explainer is at /diesel-vs-gas.
How much does it cost to fill a semi-truck with diesel?+
A Class 8 semi-truck carries 200 to 300 gallons, typically two saddle tanks of 100 to 150 gallons each. At the $6.352/gal US average, a 200-gallon fill costs $1270 and a 300-gallon fill $1906. A typical fueling stop of 100 to 150 gallons runs $635 to $953. Most owner-operators fuel strategically rather than running a tank down.
Are truck-stop diesel prices different from gas station prices?+
No public survey splits truck-stop diesel from gas-station diesel: EIA's weekly on-highway price covers retail diesel outlets as a whole, so there is no published gap to quote. Compare posted prices on your route. Where truck stops do differ is fleet-card discounts: Comdata publishes up to 40 cents/gal at TA Petro on Total Advantage (50 on Comdata Max) and 10 cents at Pilot (20 on Comdata Max) for fleets of 20 or fewer trucks, while WEX and EFS discounts are negotiated by contract. Love's Express advertises at least 20 cents/gal at Love's for new qualified customers.
How much fuel does a semi-truck use per mile?+
Class 8 trucks average 6 to 8 mpg loaded on flat highways, 4 to 6 mpg loaded on hilly terrain or under heavy loads, and 8 to 10 mpg empty. At 7 mpg and $6.352/gal, fuel cost per mile is 91 cents, or $454 for a 500-mile day. At 6 mpg loaded and hilly, the same day costs $529. Use the fleet calculator at /fleet-fuel-calculator for your own vehicle and route.
What is the best fleet fuel card for diesel discounts?+
For over-the-road truckers using multiple chains, Comdata typically offers the best discount - its advertised rates are up to 40 cents/gal at TA Petro, 10 cents at Pilot and 8 cents at Love's (for fleets of 20 or fewer trucks; larger fleets negotiate custom pricing). For owner-operators: EFS Fleet Card (WEX) discounts are negotiated by contract rather than published as a flat rate. Love's own Express card advertises at least 20 cents/gal at Love's for new qualified customers; Pilot's driver programme pays points rather than a published discount. For mixed fleets: WEX Fleet Card offers the most granular spending controls. See the full comparison at /fleet-fuel-cards.
How does the current week compare with the year so far?+
The mean of the 43 EIA weekly observations so far in 2026, through 2026-10-26, is $5.126 per gallon. The latest week reads $6.352, so the current price sits above the year-to-date mean by 1.226 per gallon. Within the last nine published weeks the series bottomed at $5.599 on 2026-08-31. EIA has not published an annual average for the current year, so this is a year-to-date mean of the weekly series and not an agency annual figure.

How We Got These Numbers

Every price figure: EIA Weekly On-Highway Diesel Fuel Price survey, week of October 26, 2026, read through the EIA Open Data API and checked against EIA's own published tables before publishing. Prices are collected Monday morning and released the same afternoon ET.

State-level prices: there is no EIA weekly diesel price for 49 of the 50 states on this site. California is the exception. Every other state carries the figure for the EIA district it sits in, labelled on the page with the district name and series id. We do not interpolate, weight or borrow from a commercial feed to manufacture a state number, which is why neighbouring states inside one district show the same price.

Truck-stop chain prices:indicative national retail estimates from each chain's published fuel-price tool (pilotflyingj.com, loves.com, ta-petro.com). These are not EIA figures and are not survey data. Confirm at the chain's app before fueling.

Reader questions: anything on this page can be queried at questions@dieselcostpergallon.com. A person reads them, answers name the survey table and week the figure came from, and where a question shows that this page left something out, the answer is added here.

Disclaimer: DieselCostPerGallon.com is an independent informational resource. We are not a fuel retailer, truck-stop operator, fleet card issuer, or affiliated with any energy company. Always confirm current pricing at the pump or via your fleet card portal before refueling.
