regular, at the pump in 1973
inflation-adjusted (CPI-U)
The average U.S. price of a gallon of regular gasoline across 1973, shown both as it was at the pump and adjusted for inflation to constant 2025 dollars. For years before 2000 this comes from EIA’s State Energy Data System (all-grades motor gasoline) and is approximate; from 2000 on it is the average of EIA’s monthly regular-grade retail prices.

1973 is an annual-average year
EIA’s weekly and monthly U.S. retail gasoline series begin in 2000, so for 1973 only an annual figure is available — there is no intra-year weekly high and low to chart. The value above is EIA’s State Energy Data System estimate (all-grades motor gasoline) and is approximate.
