U.S. motorists are set to pay the lowest Labor Day gasoline prices in five years, with crowd-sourced analytics firm GasBuddy forecasting a national average of $3.15 a gallon for the holiday weekend. The projection, echoed in an Axios report, puts prices 14 cents below last year’s level and marks the cheapest Labor Day fill-up since 2020. Government data show the trend is already in place. The U.S. Energy Information Administration’s weekly survey, published by the Federal Reserve Bank of St. Louis, pegged the average retail gasoline price at $3.15 a gallon for the week ended Aug. 25, while diesel held near $3.71. Futures markets point to further relief. On Aug. 26, September NYMEX RBOB gasoline settled at $2.1223 a gallon, with diesel at $2.2805 and natural gas at $2.7170 per MMBtu. Some analysts say pump prices could slip below $3 nationally later in the fall if crude supplies remain ample and seasonal demand eases.
