Michigan gas prices keep rising. Here's how much

Michigan gas prices on Tuesday rose 16 cents to an average of $4.18 per gallon for regular unleaded from two days earlier, according to experts.

On Monday, AAA-The Auto Group reported fuel prices in the state had risen to $4.02 per gallon for regular unleaded from the previous week, a 19-cent increase. AAA cited a decline in the domestic gasoline supply, despite a fall in demand, for the jump.

Tuesday’s average price of regular unleaded gasoline in Michigan is about 39 cents higher than a week ago, when the average was $3.79, according to AAA’s data. A month ago, the average in Michigan was $3.97 per gallon.

GasBuddy, the Dallas-based tech company that tracks fuel prices, said Michigan gas prices on Tuesday averaged about $4.21 per gallon for regular unleaded.

The firm said the average price on Tuesday was 4.3 cents higher than on Monday. The cost is also 45.3 cents more than last week’s average of $3.76 per gallon in Michigan, according to GasBuddy.

Nationally, a gallon of regular unleaded gas costs an average of $4.17 on Tuesday, according to AAA. The price is also up 6 cents from Monday, 15 cents more than last week’s average, and 20 cents higher than a month ago.

GasBuddy reported Tuesday that the national average price for a gallon of regular unleaded gas is $4.18. That compares with $4.16 on Monday, $4 last week, and a 20-cent leap from $3.97 last month.

“Average gasoline prices rose in 39 states over the last week, with the national average moving higher, while diesel prices declined in most states, offering a brief divergence at the pump,” Patrick De Haan, GasBuddy’s head of petroleum analysis, said on his company blog Monday. “However, that divergence may prove short-lived. Oil prices have been climbing again as markets react to renewed geopolitical tensions and the cancellation of talks between the U.S. and Iran.

“As a result, gasoline prices are set to rise further this week, with diesel expected to follow. Many inland states — including those in the Great Lakes and Plains — could see average gas prices climb to their highest levels since 2022, while price-cycling markets may also experience another round of hikes in the next few days.”

On Tuesday, De Haan said on X that Michigan and other Great Lakes states including Ohio and Indiana “could see a double spike week as continued refinery challenges in the region has caused a large surge in wholesale gas prices.”

Reuters reported early this month that Chicago had become the most expensive U.S. jet fuel market, with prices topping $5 per gallon, as the disruptions caused by the Iran war combined with previously scheduled refinery maintenance to leave regional supply tight.

Phillips 66’s 356,000-barrel-per-day Wood River refinery in Illinois took its crude oil unit and some other parts of the refinery offline at the end of February for a 45-day maintenance period, industry monitor IIR Energy told Reuters.

Marathon Petroleum’s 253,000-bpd Robinson refinery in Illinois also began planned maintenance in mid-March, with units expected to remain offline until mid-May, IIR said.
