RUTHERFORD COUNTY, TN - Drivers looking for a reason to smile at the pump this Monday, December 29, 2025 may want to look west— or simply stay right here at home in Rutherford County. The cheapest gas in America right now is being sold in Oklahoma, where prices dipped as low as $2.23 per gallon for regular unleaded. Iowa follows closely behind at $2.34 per gallon. However, gas prices are almost as low in the Murfreesboro / Smyrna and La Vergne, TN areas. 

Tennessee lands at number eight nationwide, with the statewide average for 87-octane gas sitting at $2.45 per gallon as of Monday morning.
