Diesel Prices Down for Third Straight Week

Diesel Prices Continue to Fall Across the U.S.

Diesel prices fell for the third consecutive week, giving truck drivers additional relief at the pump as fuel costs continued to move lower nationwide.

According to the U.S. Energy Information Administration (EIA), the national average on-highway diesel prices declined 16.4 cents to $4.668 per gallon for the week of June 29. The national average has now dropped 39.1 cents over the past two weeks.

While diesel prices have moved lower in recent weeks, they remain 94.1 cents higher than they were during the same week last year.

Diesel Prices Decline in Every Region

Every region of the country reported lower prices compared to the previous week.

The largest weekly decreases occurred on the West Coast:

• California: down 28.8 cents to $6.180 per gallon.
• West Coast (excluding California): down 27.6 cents to $4.962.
• West Coast overall: down 28.1 cents to $5.528.

Other notable declines included:

• Rocky Mountain: down 19.3 cents to $4.602.
• Midwest: down 16.8 cents to $4.583.
• Central Atlantic: down 17.8 cents to $5.190.

The Gulf Coast continued to report the nation’s lowest average diesel price at $4.283 per gallon, while California remained the highest at $6.180 per gallon.

National Diesel Prices by Region

According to the latest EIA data, average diesel prices by region are:

• U.S. Average: $4.668 per gallon (down 16.4 cents)
• East Coast: $4.758 (down 12.8 cents)
• Midwest: $4.583 (down 16.8 cents)
• Gulf Coast: $4.283 (down 13.2 cents)
• Rocky Mountain: $4.602 (down 19.3 cents)
• West Coast: $5.528 (down 28.1 cents)
• California: $6.180 (down 28.8 cents)

The Gulf Coast continued to report the nation’s lowest average diesel prices, while California remained the most expensive market for diesel fuel.

Why Diesel Prices Are Falling

The recent decline in diesel prices comes as crude oil prices have retreated sharply from their recent highs.

Oil markets have stabilized after geopolitical tensions eased, leading both Brent and West Texas Intermediate crude prices to post steep monthly declines. Lower crude oil costs typically reduce refinery and wholesale fuel costs, although retail diesel prices often take time to fully reflect those changes.

The EIA also expects prices to moderate later this year compared with recent peaks, even though diesel is still projected to average above historical levels because of higher global crude oil prices.

Gasoline Prices Also Move Lower

Although diesel price remain the primary concern for most commercial truck drivers, gasoline prices also declined during the latest reporting week.

The national average for regular gasoline fell 8.3 cents to $3.831 per gallon, marking another week of lower fuel costs across most regions of the country.

What It Means for Truck Drivers

Fuel is one of the largest operating expenses for owner-operators and small fleets. Three consecutive weeks of lower diesel prices may provide some relief, particularly for carriers that do not receive fuel surcharges.

Despite the recent declines, diesel remains nearly $1 per gallon higher than a year ago, meaning fuel continues to be a significant cost for trucking operations. The EIA’s next weekly fuel price update is scheduled for July 7.
