GasBuddy: Gas Prices Could Hit $4 Per Gallon, Diesel Reaching Multi-Year Highs03/23/2026Average prices at the pump could reach the $4 per gallon mark for the first time since 2022. GasBuddy's Head of Petroleum Analysis Patrick De Haan explains:“Gas prices continued to rise nationwide over the last week as seasonal factors, combined with ongoing supply concerns tied to the continued disruption in the Strait of Hormuz, pushed both gasoline and diesel prices sharply higher. It now appears increasingly likely that the national average price of gasoline will reach the $4-per-gallon mark—potentially as early as this week—for the first time since 2022, while diesel prices are surging to multi-year highs, with some markets nearing record territory. There are few signs of stabilization so far, as global oil prices continue to climb and early indications suggest consumers may begin to pull back in response to the rapid pace of increases.” -Patrick De Haan GasBuddy says gas prices are up more than 30 cents per gallon in Fort Wayne and Toledo in the last week.
