Diesel Prices Down Across the U.S. for Second Week

Diesel Prices Fall for Second Straight Week Across All Regions

Diesel prices continued to move lower across the United States during the week ending June 8, giving truck drivers some relief after months of elevated fuel costs.

According to the latest data from the U.S. Energy Information Administration (EIA), the national average on-highway diesel price fell 14 cents to $5.21 per gallon. The decline follows a 17.3-cent drop the previous week.

Despite the recent decreases, prices remain $1.74 per gallon higher than they were one year ago.

Gasoline prices also moved lower nationwide. The average price for regular gasoline fell 15.9 cents to $4.15 per gallon.

Diesel Prices Decline in Every Region

All major regions reported lower prices during the week.

The Midwest posted the largest decline, with diesel prices falling 21 cents to $5.18 per gallon.

Other regional averages included:

• East Coast: $5.15 per gallon (-8.8 cents)
• Gulf Coast: $4.79 per gallon (-11.4 cents)
• Rocky Mountain: $5.20 per gallon (-13.1 cents)
• West Coast: $6.29 per gallon (-10.9 cents)

The Gulf Coast continued to report the nation’s lowest average diesel price at $4.79 per gallon.

The West Coast remained the most expensive region at $6.29 per gallon.

California Diesel Prices Remain Highest in the Nation

California continued to have the highest diesel price in the country.

The state’s average diesel price fell 11.1 cents during the week but remained at $6.94 per gallon.

That is nearly $1.73 per gallon above the national average.

Meanwhile, the average diesel price outside California but within the West Coast region was $5.73 per gallon.

Diesel Prices Remain Well Above Last Year’s Levels

While diesel prices have fallen during the past two weeks, fuel costs remain significantly higher than a year ago.

Compared to the same week in 2025:

• U.S. diesel prices are up $1.74 per gallon.
• West Coast: up $2.07 per gallon.
• California: up $2.20 per gallon.
• Gulf Coast: up $1.68 per gallon.

The higher year-over-year prices continue to affect operating costs for owner-operators and small fleets that purchase fuel on the spot market.

Gasoline Prices Also Move Lower

The national average gasoline price fell 15.9 cents to $4.15 per gallon.

The Midwest saw the largest weekly gasoline decline, dropping 19 cents to $3.95 per gallon.

The Gulf Coast recorded the nation’s lowest gasoline average at $3.64 per gallon, while the West Coast remained the highest at $5.36 per gallon.

California was again the most expensive state in the nation, with gasoline averaging well above the national average.

What Diesel Prices Mean for Truck Drivers

The latest EIA report marks the second consecutive week of lower diesel prices nationwide.

While fuel costs remain much higher than last year, the recent declines may provide some relief for trucking companies and owner-operators managing fuel expenses during the summer freight season.

Drivers will be watching closely to see whether diesel prices continue to move lower in the coming weeks or if seasonal demand and global energy markets push costs back upward.
