Charlotte gas prices drop 3 cents over the week

Gas prices in the Charlotte region and the rest of the U.S. declined over the week as domestic oil supplies continue to keep fuel costs in check.

Over the last week, the average price of a gallon of unleaded gas in the Charlotte area fell 3 cents, according to auto group AAA. Drivers currently pay 91 cents a gallon less for gas compared with one year ago.

South Carolina remains the state with the cheapest gas in the nation.

Nationally, gas prices are the lowest they have been since February and could continue dropping, said AAA, which surveys 120,000 stations across the U.S. to determine average prices.

“Barring any unanticipated disruptions in supply, and/or spikes in the price of crude oil, the national average could fall below the $2 per gallon threshold for the first time since 2009 before the end of year,” AAA said in a report this week.

Below are local and national gas prices as of early Tuesday.
