GasBuddy: Average Gas Prices Could Increase Amid Geopolitical Tensions04/27/2026There’s a chance that gasoline and diesel prices could go up again. GasBuddy's Head of Petroleum Analysis Patrick De Haan explains:“Average gasoline prices rose in 39 states over the last week, with the national average moving higher, while diesel prices declined in most states, offering a brief divergence at the pump,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “However, that divergence may prove short-lived. Oil prices have been climbing again as markets react to renewed geopolitical tensions and the cancellation of talks between the U.S. and Iran. As a result, gasoline prices are set to rise further this week, with diesel expected to follow. Many inland states— including those in the Great Lakes and Plains— could see average gas prices climb to their highest levels since 2022, while price-cycling markets may also experience another round of hikes in the next few days.” -Patrick De Haan.Over the last week, gas prices in Fort Wayne have fallen 14.8 cents per gallon, averaging $3.56 per gallon on Monday. Gas prices in Toledo have risen 26.3 cents per gallon, averaging $3.86 per gallon.
