Diesel Prices Reach New All-Time High, Surpassing 2022 Record – GasBuddy

GasBuddy, North America’s trusted fuel savings platform for more than 25 years, announced that the national average price of diesel has reached a new all-time record high of $5.85 per gallon, continuing to climb and surpassing the previous record of $5.82 per gallon set in June 2022.

While gasoline prices often dominate headlines, diesel can have a much broader impact on inflation and business costs. Diesel powers much of the U.S. economy, including freight trucks, trains, agricultural equipment, and construction machinery. As diesel prices rise, transportation costs increase, often leading to higher prices for consumer goods and services.

According to GasBuddy data, more than 515,000 unique users reported fuel prices in August 2026 alone, contributing to one of North America’s most comprehensive real-time fuel price datasets and reflecting the scale of GasBuddy’s highly engaged consumer driver community.

“Diesel is the fuel that moves the economy, and when diesel prices reach record levels, the impact extends far beyond the transportation sector,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Higher diesel prices impact consumers as rising supply chain costs increase the price of groceries, household goods, deliveries, and countless other products Americans rely on every day.”

Diesel prices have climbed sharply in recent months as geopolitical tensions and supply chain disruptions continue to drive volatility in global energy markets. Higher oil prices, reduced refining capacity abroad, and tight global inventories have all contributed to rising diesel and gasoline prices. As a result, diesel prices are up over $2/gal from a year ago (September 2025: $3.70/gal diesel).
