Tracking average gas prices in Mass.

If there's one thing people in Massachusetts aren't looking forward to these days, it's topping off their gas tank.

Bay State drivers have become grudgingly accustomed to paying well north of $4 per gallon after Russia's invasion of Ukraine in late-February sent shockwaves through global oil markets. The war in Europe came as prices were already creeping up at home, with the U.S. grappling with inflation not seen in decades.

Average gas prices eclipsed the $5-per-gallon threshold in June after a parade of record-setting months. Since that peak, prices have been inching down about 10 cents each week.

Soaring gas prices are a nationwide problem, and the Biden administration announced in March it would begin regular withdrawals from U.S. oil reserves in a bid to tamp down the trend. But it's unclear how quickly or how much the move will make a difference. Massachusetts members of Congress have also directed criticism toward oil and gas corporations.

For now, the pump is yet another place where rising consumer costs have put a deeper-than-usual dent into people's expenses.

Take a look at the chart below to see how gas prices are changing week-to-week. We'll be updating it each Monday as AAA releases its latest data, based on a survey of thousands of self-serve gas stations across Massachusetts.
