"Average gasoline prices rose in nearly three out of five states over the last week, while diesel surged in every state — with some climbing nearly 50 cents per gallon in just seven days. The milestone many hoped to avoid has arrived: the national average price of gasoline on Labor Day set a new all-time record for the holiday, eclipsing the previous mark of $3.83 per gallon set in 2012," said Patrick De Haan, head of petroleum analysis at GasBuddy.
"Diesel's record fell as well, with the national average reaching $5.87 per gallon on September 3, surpassing the prior all-time high of $5.82 per gallon set in 2022 — and with $6 per gallon now a realistic possibility in the weeks ahead if Ukraine's continued attacks on Russian refining infrastructure keep knocking capacity offline. These are sobering milestones, and until the global refining supply picture meaningfully improves, both diesel prices face continued upward pressure while gasoline may seasonally slow in the weeks ahead."
