What It Means
Looking ahead, diesel prices could continue to decrease due to ongoing global oil market trends and domestic fuel demand. However, regional differences are expected, particularly in areas like the West Coast, where factors like supply chain dynamics and environmental regulations can cause price fluctuations.
