Gas prices continued an eight-week slide on Monday with the state average for Arkansas dipping to $2.22 a gallon.

Prices in Arkansas are 10.3 cents per gallon lower than a month ago, yet stand 33.8 cents per gallon lower than a year ago.

The national average price of gasoline has also fallen about a penny in the last week, averaging $2.55 on Monday. The national average is down 9.9 cents per gallon from a month ago, yet stands 28.7 cents per gallon lower than a year ago.

"For its eighth straight week, the national average has declined even as oil prices have bucked the trend in the last week, moving higher on optimism over upcoming trade talks between China and the United States," Patrick DeHaan, head of petroleum analysis for GasBuddy, explained in a news release.

If trade talks between the U.S. and China fall apart, DeHaan expects more price declines that will accelerate in the weeks ahead.

“Gasoline demand in early September generally declines alongside stock levels as refineries prepare for the switchover to winter-blend gasoline and undergo maintenance,” Jeanette Casselano, AAA spokesperson, noted in a news release. “These typical trends mean savings for motorists, leading the way for potentially some of the cheapest gas prices at the end of the year.”

While state averages range from as expensive as $3.65 in Hawaii to as cheap as $2.16 in Mississippi, nearly all state averages are 20 to 55 cents cheaper than this time last year.
