June 6, 2023

The report released on June 5 showed the national diesel price average on Monday was $3.921 per gallon, down 4.5 cents from last week.

ProMiles produces a report that is similar to one published weekly by the federal Energy Information Administration. A key difference between the two reports is the type and number of fueling stations in order to calculate its averages. While ProMiles uses its direct feed from thousands of truck stops to develop its averages, EIA surveys 400 truck stops and convenience stores nationwide. The EIA report is also the average price of diesel for the previous week.

With decreases across the board, only one region now has a price above $5 per gallon.

A drop of 7.5 cents in the Central Atlantic was the greatest decline across all regions. The West Coast region reported a drop of 5.2 cents and the East Coast was down 4.7 cents. The Gulf Coast’s average price per gallon was around 4 cents lower this week.

The Rocky Mountain region’s price was most similar to last week, reporting a change of less than 1 cent.

According to the June 5 ProMiles report, five regions now have an average price per gallon below $4.

At $3.494 per gallon, the Gulf Coast region reported the lowest average price of any region this week.
