Diesel Prices Rise Again in Latest Weekly Fuel Update

Diesel Prices Climb to $3.897 in Weekly EIA Update

Diesel prices moved higher across the U.S. in the latest weekly fuel report from the U.S. Energy Information Administration (EIA). The national average price for on-highway diesel reached $3.897 per gallon for the week of March 2, 2026.

That marks an increase of 8.8 cents from the previous week, when diesel averaged $3.809 per gallon.

For truck drivers and fleets, fuel costs remain one of the biggest operating expenses. The latest increase continues a trend of rising prices over the past several weeks.

Diesel Prices Increase Across Most Regions

The EIA report shows diesel prices rose in every major U.S. region last week. The East Coast average climbed 8.1 cents to $3.924 per gallon. Within that region, New England recorded one of the largest increases, jumping 11.3 cents to $4.314 per gallon. In the Midwest, diesel prices rose 9.0 cents, bringing the regional average to $3.888 per gallon.

The Gulf Coast, which typically has some of the lowest fuel prices in the country, saw diesel increase 10.9 cents to $3.598 per gallon. Meanwhile, the price in the Rocky Mountain region increased 5.4 cents, reaching $3.737 per gallon. On the West Coast, diesel rose 6.9 cents to an average of $4.534 per gallon. California remained the most expensive market, where prices reached $4.990 per gallon.

Diesel Prices Remain Higher Than Last Year

Although diesel prices are still below levels seen two years ago, they remain higher than the same week in 2025. The national diesel average is currently 26.2 cents higher than one year ago, according to EIA data.

This year-over-year increase shows that fuel costs continue to put pressure on trucking operations, especially for owner-operators and small fleets. Because prices directly affect freight rates and operating costs, many drivers closely monitor weekly changes.

Gasoline Prices Also Rose Last Week

Gasoline prices also increased nationwide during the same reporting period. The national average price for regular gasoline rose to $3.015 per gallon, up 7.8 cents from the previous week.

Several regions saw notable increases:

• Midwest: up 11.9 cents to $2.794
• Gulf Coast: up 11.2 cents to $2.644
• Lower Atlantic: up 8.2 cents to $2.830
• West Coast: up 4.9 cents to $4.160

Although gasoline prices are not as critical for heavy trucking as diesel, they still influence broader transportation and consumer costs.

Why Diesel Prices Matter for Truck Drivers

For the trucking industry, diesel prices are closely tied to freight costs and profit margins.

When the diesel price rises, carriers often adjust fuel surcharges to offset higher operating costs. However, those adjustments may not always fully cover increases, especially in the spot market. Higher prices can also influence:

• freight rates
• delivery costs
• trucking company expenses
• consumer prices for goods

Because trucks move most freight in the U.S., fuel trends can ripple through the entire supply chain.

Diesel Prices Continue to Be a Key Industry Indicator

Weekly fuel reports from the EIA are widely watched across the trucking industry. Many carriers, brokers, and logistics companies track diesel prices to help predict cost changes in freight transportation.

If diesel prices continue rising in the coming weeks, trucking companies may face additional cost pressure heading into the spring shipping season.

The next EIA fuel price update is scheduled for March 10, 2026.
