TAMPA, Fla. (May 29, 2018) -- Motorists should soon catch a break from rising gas prices. Oil and gasoline futures prices plunged after Russia and Saudi Arabia expressed interest in raising oil supply.

"This news couldn't come at a better time, as motorists roll into the summer driving season," said Mark Jenkins, spokesman, AAA - The Auto Club Group. "The drop in crude should amount to a discount of at least 10 cents at the pump, in the short term. Yet that will not happen overnight. Retailers are usually slow to lower prices, especially those who bought shipments of gasoline when prices were at a premium."

Gas prices in Tennessee increased 6 cents during the past week. The state average on Memorial Day was $2.73 - the most expensive for the holiday since 2014, when the average price was $3.45 per gallon.

Tennessee motorists are paying 62 cents per gallon more than a year ago. It now costs $41 to fill an average-size tank of gasoline - an increase of nearly $10.

The most expensive gas price averages in Tennessee are in Jackson ($2.77), Nashville ($2.76), Knoxville ($2.72)

The least expensive gas price averages in Tennessee are in Johnson City ($2.66), Chattanooga ($2.66), Clarksville-Hopkinsville ($2.69)
