As of April 20, 2026, the national average price for regular gasoline in the United States has decreased slightly to $4.042 per gallon, providing some relief to drivers after a period of high prices. However, significant regional disparities persist. California continues to have the highest prices, averaging $5.837 per gallon, driven by strict environmental regulations and high taxes. In contrast, Oklahoma boasts the lowest average at $3.376, benefiting from proximity to refining hubs and lower taxes. Other states like Texas ($3.656) and Florida ($3.990) also offer prices below the national average, while New York ($4.105) and Washington ($5.385) remain above it. The differences in gas prices reflect various factors, including state taxes, environmental requirements, and logistics, emphasizing that where you live greatly influences fuel costs.
