The national average price of gasoline remained steady heading into Labor Day at $2.84 per gallon, which is 2 cents cheaper than a month ago and 48 cents higher than a year ago, according to AAA. Certain states have seen their average price decline as much as 4 cents.

"With Labor Day approaching, motorists could see a small swing towards higher gas prices, but any jump should not last past the holiday weekend," said Jeanette Casselano, AAA spokesperson.

A year ago, gasoline prices spiked during the Labor Day weekend due to Hurricane Harvey, which shut down refineries and pipelines as it battered the southeast region. The national average price reached $2.67.

States with the most expensive gasoline include Hawaii ($3.76), California ($3.60), Washington ($3.37), Alaska ($3.32), Idaho ($3.26), Oregon ($3.25), Utah ($3.20), Nevada ($3.19), Connecticut ($3.04), and Pennsylvania ($3.03).

States with the biggest weekly changes include Ohio (up 10 cents), Michigan (up 5 cents), Wyoming (up 4 cents), Florida (down 4 cents), Colorado (up 3 cents), South Dakota (down 3 cents), Georgia (down 3 cents), Kansas (down 3 cents), Missouri (down 3 cents), and Utah (up 2 cents).

Meanwhile, the average price of a gallon of diesel increased 1.9 cents to $3.226, which is 62.1 cents higher than it was a year ago, according to the U.S. Energy Information Administration.
