Massachusetts gas prices remain at record high $4.73 a gallon

BOSTON - Gas prices in Massachusetts remained at a record high of $4.73 a gallon Monday, according to AAA. They have not risen since reaching that level last Thursday.  

Prices are up 13 cents a gallon in the last week. A year ago, it was $2.91 a gallon, $1.82 less.

"Gasoline is $1.19 more than it was the week of Russia's invasion of Ukraine," AAA's Mary Maguire said in a statement Monday. "That sent shock waves through the oil market that have kept oil costs elevated. Domestically, meanwhile, seasonal gas demand is rising as more drivers hit the road, despite the pain they face paying at the pump."

The national average is currently $4.59 a gallon, which is also a record, according to AAA.

California still has the highest prices in the country, with an average of $6.06 a gallon.

Diesel prices continued their slow decline and are now averaging $6.35 a gallon in Massachusetts as of Monday. That's six cents lower than the record set Wednesday of $6.41.
