National Gas Price Average Dropping Toward Lowest of the Year

November 26, 2018 - On the week, the national gas price average has dropped seven cents to land at $2.56. As pump prices steadily decline, they are headed toward some of the cheapest gas prices in 2018. The national average was lowest in January at $2.49 while May brought the most expensive price of $2.97.

“Trends are indicating that the month of December may bring some of the cheapest gas prices of the year,” said Marilyn Buskohl, AAA spokesperson. “U.S. gasoline demand remains low and supply plentiful so motorists can expect to save at the pump as long as the price of crude oil doesn’t spike. Here in South Dakota the statewide average stands at $2.56, down 5 cents from one week ago.”

Gas prices have been cheaper in the U.S. as crude oil sells at $57/bbl and cheaper - the lowest prices of the year.
