The national gas price average is $2.18, which is the cheapest start to the month of October since 2016, according to AAA.

That average is the same as a week ago, four cents cheaper than the start of this past September and nearly 50 cents cheaper than last year, AAA said. The national average held on the week as demand was mostly stable at 8.5 million barrels per day despite gasoline stocks increasing by 700,000 barrels.

“Demand is likely to see some declines in the weeks ahead as drivers traditionally take fewer road trips in the fall,” said Jeanette Casselano McGee, AAA spokesperson. “That will mean gas prices are likely to push cheaper throughout the month.”

The nation’s top 10 largest weekly changes are Florida (up 9 cents), Delaware (up 6 cents), New Jersey (up 6 cents), Washington, D.C. (up 5 cents), Michigan (down 5 cents), West Virginia (up 4 cents), Maryland (up 3 cents), Kentucky (down 3 cents), Idaho (down 3 cents) and Indiana (down 3 cents). 

Meanwhile, the nation’s least expensive markets are Mississippi ($1.84), Texas ($1.85), Arkansas ($1.87), Oklahoma ($1.87), Missouri ($1.87), Louisiana ($1.88), Alabama ($1.89), South Carolina ($1.91), Tennessee ($1.93) and Kansas ($1.95).
