U.S. gas prices by week since 1991

Until 2022, gas prices had peaked in the U.S. in the summer of 2008, topping $4 per gallon for regular, conventional gasoline.

This is only for regular grade gasoline and conventional gas (not reformulated, which is more expensive and mandated in some parts of the U.S.)
