GasBuddy: Uncertainty at the Pump After Gas Price Spike05/04/2026There could be some uncertainty at the pump in the near term. GasBuddy's Head of Petroleum Analysis Patrick De Haan explains:“Gasoline prices rose in every state over the last week, with some of the most significant and fastest increases concentrated in the Great Lakes, where states like Michigan, Indiana, Ohio, and Illinois saw sharp spikes, while Wisconsin experienced more modest gains. At the same time, diesel prices surged to new records in parts of the region, with some areas touching the $6-per-gallon mark. While refinery outages were a key driver behind those outsized increases, early signs of improvement could help ease some of the most extreme price pressures in the Great Lakes in the days ahead. Beyond the region, markets are also digesting a wave of new developments— including OPEC+ raising production for June and President Trump outlining a plan to free stranded ships— which could help restore some supply. However, with so many moving pieces, the outlook remains highly fluid, and while some localized relief may emerge, broader price volatility is likely to persist in the near term.” -Patrick De HaanAverage gasoline prices in Fort Wayne have risen $1.35 per gallonin the last week, averaging $4.91 pergallon Monday.
