Can gasoline prices at the pump in Wisconsin be changed more than once a day?

On the retail sale of gasoline in Wisconsin, state law states: 

“All prices posted shall remain in effect for at least 24 hours after they are posted.”

The law is aimed at protecting consumers from deceptive advertising.

In 2026, the Department of Agriculture, Trade and Consumer Protection issued a warning to at least one gas retailer after receiving complaints that prices were raised more than once in 24 hours.

Gas prices have been volatile since the start of the Iran war in February.

As of Nov. 9, the average price for a gallon of regular gas in Wisconsin was $3.92, according to AAA.

A week earlier, the average was $4.23.

A year earlier, it was $2.85.

The record-high average gas price in Wisconsin hit $4.92 in June 2022, but exceeded $5 in six southeastern counties.
