AAA: Good news, bad news on gas prices

June 18, 2018 - South Dakota drivers are finding both good news and bad news at the pump. The good news is that local gas prices continue to drop slightly but the bad news is that many areas are seeing prices between 50 and 60 cents higher than one year ago.

“Drivers may be enjoying a continued drop in gas prices but they shouldn’t get too comfortable with it,” said Marilyn Buskohl, AAA spokesperson. “Motorists can expect to spend an average of $200 more on gas this season, fueled by the price of crude and the high demand for gasoline.”

With strong summer consumer gasoline demand expected in the months ahead, AAA says motorists can expect little relief at the pump with the national gas price average ranging between $2.85 and $3.05 through Labor Day.

On the week, the national gas price average is two cents cheaper at $2.90. Today’s national average is only one cent more expensive than a month ago, but 60 cents more expensive than a year ago.

Nationwide, 44 states have less expensive or steady gas price averages compared to last Monday. However, the cheaper trend may be reversing. Gasoline demand spiked in the latest Energy Information Administration’s (EIA) report, in fact setting a new all-time record at 9.88 million b/d for the week ending June 8. As demand skyrockets, U.S. gasoline inventories plummeted 2.27 million bbl, to land total inventories at 237 million bbl, which is 5.7 million below stocks last year at this time.

“If demand continues to strengthen and inventories decrease in the weeks ahead, motorists can expect gas prices do a reversal and start to increase again,” said Buskohl, AAA spokesperson. “AAA expects the national gas price average to range between $2.85 and $3.05 through Labor Day, likely seeing the summer’s highest prices in June.”
