U.S. retail gasoline prices in 2023 averaged $0.43 per gallon (gal) less than in 2022, according to data from our Gasoline and Diesel Fuel Update. This decline was due, in part, to lower crude oil prices in 2023 compared with 2022 and higher gasoline inventories in the second half of 2023. Compared with the last weekly average price snapshot of 2022, prices during the last week of 2023 were about even, up only $0.02/gal.
