GasBuddy: Fuel Prices Could Increase Amid Ongoing Iran War Tensions04/13/2026You should prepare for another possible round of gasoline and diesel price increases. GasBuddy's Head of Petroleum Analysis Patrick De Haan explains,“Average gasoline prices surged for many Americans through the first half of last week before easing in some areas after oil prices slipped following President Trump’s announcement of a ceasefire. However, with a breakdown in talks and renewed escalation over the weekend, motorists should prepare for another round of price increases. The move toward a full blockade of the Strait of Hormuz is compounding global supply concerns and risks further disrupting flows, which pushed oil prices sharply higher in Sunday night trading. As a result, gasoline prices are likely to jump again this week, with diesel expected to follow, until there is a meaningful restoration of shipping through the Strait.” -Patrick De HaanOver the last week, average gas prices in Fort Wayne rose 12.3 cents per gallon, averaging $3.91 today, and are up 15.8 cents per gallon in Toledo for an average of $3.84 per gallon.
