Regional Analysis

East Coast (PADD 1): Diesel prices in the region declined by an average of 6.7 cents this week to $3.619. New England (PADD 1A) dropped 4.8 cents, the Central Atlantic (PADD 1B) went down 6.1 cents, and the Lower Atlantic (PADD1C) showed the region’s biggest weekly decline at 7.2 cents.

Midwest (PADD 2): The Midwest saw the largest weekly price decline, 8.5 cents to $3.528. The drop can be attributed to reduced agricultural fuel demand and stable refinery output, which improved supply availability in the region.

Gulf Coast (PADD 3): Diesel prices along the Gulf Coast decreased 7.5 cents to $3.190, continuing its trend as the region with the lowest diesel prices. The region benefits from its proximity to major refining operations, helping to keep prices lower and driving this significant weekly decline.
