The national average for diesel has reached $4.264 per gallon, the highest level since Nov. 21, 2023. A week ago, diesel averaged $3.752 per gallon, marking a 51.2-cent jump in just one week — one of the most dramatic weekly increases seen in years, wrote Patrick De Haan, head of petroleum analysis at GasBuddy.
Iowa saw an even larger increase, with the average diesel price jumping 67 cents in a week, tied with Texas for the largest increase in the country.
