(The Center Square) – The average price of a gallon of unleaded gas in Wisconsin rose to $4.20 on Thursday morning, up from just more than $2.50 in late February and below $3.70 just 10 days ago, according to GasBuddy.
Numbers from the American Automobile association showed a $4.16 per gallon average on Thursday, up from $3.96 on Wednesday and $3.68 a year before. That’s up from $2.97 a year ago.
The average price of a gallon of gas across the country reached $4.30 on Thursday, the highest price since July 2022 according to GasBuddy Head of Petroleum Patrick DeHaan.
Gas prices in Michigan, Indiana, Ohio, Illinois and Wisconsin are now at their highest levels since summer 2022, and are approaching new all-time records— Patrick De Haan (@GasBuddyGuy) April 30, 2026
Part of the reason for the jump in the oil market is the conflict in the Middle East along with discussions and disagreements between the U.S. and Iran over the Strait of Hormuz, AAA told The Center Square.
Another part of what impacted the prices across the Midwest, according to GasBuddy, is limited spare refining capacity in the region, following a power outage Sunday at a BP refinery in Whiting, Indianq, near Chicago.
