NEW YORK — US diesel prices fell below $6 a gallon on Saturday, November 14, averaging $5.998 nationwide, according to fuel price tracker GasBuddy, the first reading under the $6 mark in two months after a record-breaking autumn surge.
Diesel hit $5.820 a gallon on September 3, breaking the record set after Russia’s 2022 invasion of Ukraine, topped $6 on September 10 and peaked at $6.519 on September 22. In California, where refining capacity is tight, prices briefly exceeded $10 a gallon.
Key Takeaways
- US diesel averaged $5.998 a gallon on Saturday, the first sub-$6 reading since early September, per GasBuddy data.
- Prices peaked at a record $6.519 on September 22; California briefly topped $10 a gallon.
- Brent crude futures are down 18.5% in two weeks, and US gasoline is below $4 for the first time since August 10.
- The US Energy Information Administration’s weekly diesel average fell to $6.127 for November 9, down 16.5 cents in a week.
Why US Diesel Prices Fell Below $6 a Gallon
Two forces are pulling together: easing supply fears and weaker seasonal demand. Diesel surged in the autumn as the US-Israeli war against Iran disrupted oil supplies and Ukrainian strikes on Russian refineries cut fuel output. With tensions easing, Brent crude futures are down 18.5% over the past two weeks.
Seasonal factors are helping. Demand usually softens in the autumn as people drive less, hurricane season winds down and the risk of Gulf Coast refinery disruption falls away. Refinery maintenance is also largely finished by November, letting production recover, according to Patrick De Haan, GasBuddy’s head of petroleum analysis.
The Trump administration has moved to ease fuel costs, temporarily lifting federal taxes on red-dyed diesel, easing sanctions on Russian fuel and launching an $8 billion support programme for farmers hit by higher fuel costs. Those measures gave only limited relief while supply concerns tied to the war in Iran dominated the market.
How Lower Diesel Prices Affect Trucking, Food and Inflation
Diesel is a key driver of transport and freight costs, so the autumn surge fed straight into the price of moving goods. Elevated diesel pushed up overall inflation and added to cost pressures on consumers, farmers and businesses. High fuel costs ranked among the issues voters cited in this month’s midterm elections, which handed Democrats control of both houses of Congress. October’s consumer price index rose 0.4% in the month.
US Diesel Prices by State: Where Fuel Costs Most and Least
The national average hides wide gaps. The US Energy Information Administration’s weekly figures for November 9 put the Gulf Coast cheapest and the West Coast dearest, with California far above the rest.
| Region | Diesel per gallon | Weekly change |
|---|---|---|
| US average | $6.127 | −$0.165 |
| East Coast | $5.920 | −$0.105 |
| Midwest | $6.201 | −$0.201 |
| Gulf Coast | $5.741 | −$0.171 |
| Rocky Mountain | $6.206 | −$0.239 |
| West Coast | $7.110 | −$0.162 |
| California | $7.897 | −$0.179 |
Every region fell in the latest weekly reading, with the Rocky Mountain region down the most at nearly 24 cents. Even so, West Coast drivers still pay close to $1 a gallon more than the national average, and California remains almost $1.90 above it.

Frequently Asked Questions
How much is diesel per gallon in the US right now?
The national average retail diesel price was $5.998 a gallon on Saturday, November 14, according to GasBuddy data. The US Energy Information Administration’s weekly on-highway average, from a different survey, stood at $6.127 for the week of November 9.
Why did diesel prices fall below $6 a gallon?
Easing geopolitical tensions and weaker seasonal demand pulled prices down. Brent crude futures have fallen 18.5% in two weeks as supply fears tied to the war in Iran eased, while autumn demand softened and refinery maintenance finished.
Will diesel prices keep falling?
That depends on whether crude prices keep sliding and on the war in Iran and Ukrainian strikes on Russian refineries, which pushed prices to records in September. GasBuddy’s daily readings will show whether the sub-$6 level holds.
How do lower diesel prices affect inflation and grocery prices?
Diesel powers most freight, so cheaper fuel lowers the cost of moving food and goods, easing pressure on consumer prices. The relief reaches shelves with a lag of weeks, and only if lower pump prices hold.
The next weekly fuel update from the US Energy Information Administration is due on Monday.
