OKLAHOMA CITY — AAA Oklahoma says gasoline prices are plunging following the Labor Day holiday and the end of the busy summer driving season.

AAA spokesman Chuck Mai said Tuesday that the statewide average price for a gallon of self-serve regular gasoline is down 7 cents since August 30. But Mai says the decline is even more dramatic in Tulsa, where the citywide average has plummeted 14 cents since August 31. Oklahoma City’s average has fallen 11 cents since August 30.

Pump prices are also declining nationally. South Carolina reports the lowest statewide average at $1.94, followed by Alabama at $1.97, Mississippi at $1.98 and New Jersey at $1.99. AAA says Oklahoma has the nation’s 11th-lowest state average price.

Tuesday’s national average gas price is 2 cents less than a week ago.
