Diesel Drops 16.5 Cents in a Week to $6.127 a Gallon, Its Biggest Weekly Drop Since Early October

By Big Rig Daily Staff

The national average price of diesel fell 16.5 cents in one week, from $6.292 to $6.127 a gallon, according to the U.S. Energy Information Administration's weekly diesel price data released Nov. 10, as The Trucker reports. It was the biggest one-week drop since early October, EIA's weekly figures show. Diesel fell further in some earlier weeks after the Iran war began, including a 22.7-cent weekly drop in late June.

The drop follows a 6-cent decline the week before, when the average fell to $6.292.

Where prices fell most

The Rocky Mountain region posted the largest decline, nearly 24 cents, from $6.445 to $6.206 a gallon, The Trucker reports. The Midwest fell just over 20 cents, from $6.402 to $6.201.

Oil is sliding too

The Associated Press reported that oil prices kept falling, with Brent crude, the international benchmark, dropping below $91 a barrel, its lowest level in three months, according to The Trucker. Brent fell 2.2%, or $2.02, to $90.55 a barrel, while U.S. benchmark crude slid 1.8%, or $1.65, to $84.94.

The declines came after President Donald Trump said the war in Iran "militarily is effectively over," The Trucker reports.

Gasoline under $4

Transport Topics reports that the U.S. average price of regular gasoline slipped below $4 a gallon, to $3.98 on Nov. 9, according to AAA. It was the first time the average had fallen below $4 since mid-July.

Transport Topics also notes that pump prices typically fall more slowly than they rise, and that any renewed conflict could send prices up again. Retail diesel remains above $6 a gallon after crossing that mark for the first time in September.

What it means at the pump

Even after the drop, diesel is still above $6. As a simple illustration, a truck running 2,500 miles a week at about 6 miles per gallon burns roughly 417 gallons. At $6.127 a gallon, that is still more than $2,500 a week in fuel. Actual mileage and prices vary by truck, load and region.

Why it matters to truckers

A 16.5-cent drop saves about $69 on that 417-gallon week. It is real relief, but diesel is still above $6 a gallon, a level it first crossed in September.
