EIA diesel benchmark falls 14.7 cents to $6.382 as Gulf crude flows recover

Andy Will, Chief Editor · Wednesday, September 30, 2026

The diesel price that sets most fuel surcharges dropped 14.7 cents to $6.382 a gallon, the first decline in four weeks. The Energy Information Administration published the weekly average Tuesday, effective Monday, and it breaks a three-week run where the number hit a new record every week. For carriers billing surcharges off that figure, it is the first break they have had this month.

The reason is supply. Crude flowing out of the Persian Gulf is getting back toward pre-war levels, and that is pulling oil prices down. FreightWaves tied the diesel move directly to it.

The catch for haulers

The relief is thin against where costs are. David Parker of Covenant Logistics told FreightWaves operating costs are up 40 to 50 percent since 2019, with driver pay up around 50 percent. One 14.7-cent week off a $6.38 benchmark does not undo that. It trims the surcharge line and little else.

Russia's ban

Russia extended its ban on diesel, marine fuel and gasoil exports for producers through October 31. That keeps barrels off the global market at the same time Gulf crude is easing. The two pull opposite directions on price, which is why the diesel drop could stall if Russian supply stays bottled up.

Trump's export talks

Trump held crisis talks over a possible US diesel export ban, the Times reported. Keeping more diesel at home could soften US prices near term, though it would scramble Gulf Coast refiners who sell abroad. Nothing is decided. Worth tracking for anyone whose supply comes off Gulf Coast racks.

Dyed diesel pause

Oklahoma Governor Kevin Stitt called for a pause on dyed diesel enforcement while fuel costs stay high, which would let off-road users burn tax-exempt fuel with less exposure. It is a narrow state-level cost move. It also signals how much pressure retail diesel is putting on operators.

Biodiesel credit

Grassley and Klobuchar introduced S. 5583 to extend the Small Agri-Biodiesel Producer Credit through 2029. The credit is set to expire December 31, 2026. It runs 20 cents a gallon on the first 15 million gallons for producers making 60 million gallons a year or less, using crop oils and animal fats. For small blenders that is production certainty. For haulers moving biodiesel it keeps the volume in play.

What to watch

Whether next week's EIA print extends the decline or the Russian ban pushes it back up. And whether Trump's talks turn into an actual policy that reroutes Gulf Coast diesel, which could move US rack prices before the crude picture does.
