When was gasoline a dollar a gallon?

Gasoline prices briefly reached around a dollar a gallon in the late 1990s and early 2000s in the United States, particularly around 1998 and 1999. Prices fluctuated due to various factors, including supply and demand, geopolitical events, and changes in crude oil prices. However, by the mid-2000s, prices began to rise significantly, and it became rare to see gasoline at that price point again.
