AAA: Michigan Gas Prices Down a Few Pennies Compared to Last Week

The Michigan state average is still $1.10 more than this time last year

DEARBORN, Mich., (September 20, 2021) - Gas prices in Michigan are down 2 cents compared to last week. Michigan drivers are now paying an average of $3.16 per gallon for regular unleaded. This price is 6 cents less than this time last month but still $1.10 more than this time last year.

Motorists are paying an average of $47 for a full 15-gallon tank of gasoline; an increase of about $8 from when prices were their highest last January.

Last week, the national average for a gallon of regular gasoline increased two cents to $3.19, tying early August peaks and matching a 7-year-high. Much of the rise was due to impacts from Hurricanes Ida and Nicholas on oil and refinery production. Approximately 30% of crude production in the Gulf of Mexico remains shuttered, according to the U.S. Bureau of Safety and Environmental Enforcement. Reduced crude production combined with gradual refinery restarts has led to a drop in the percent of crude utilization nationwide by just over 9% to 82.1%, according to the most recent weekly report from the Energy Information Administration (EIA). Meanwhile, total domestic stocks took another step back by 2 million bbl to 218 million bbl.

At the close of Thursday's formal trading session, WTI closed at $72.61. Prices increased last week due to the market reacting to impacts from Hurricanes Ida and Nicholas. The price per barrel hit a high of $72, a level not seen since July. Industry reports show that Hurricane Ida has reduced crude supplies by about 30 million bbl, causing a month-to-month reduction of the global supply of 540,000 b/d. Domestically, tightened crude supplies will likely be offset by less gas demand after Labor Day, which decreased from 9.61 million b/d to 8.89 million b/d in EIA's new weekly report.

"Despite decreased demand after Labor Day, the impact of the hurricanes and the latest crude price increases could help pump prices remain above $3 a gallon in the weeks ahead," said Adrienne Woodland, spokesperson, AAA-The Auto Club Group.

Compared to last week, Metro Detroit's average daily gas price dropped slightly. Metro Detroit's current average is $3.26 per gallon. This price is 1 cent less than last week's average and $1.13 more than this same time last year.
