Gas prices today April 20: Check latest weekly average rates in California, Texas, Florida, New York, Washington and more

The latest figures from AAA show that the US national average for regular gasoline has edged slightly lower to $4.042 per gallon as of April 20, 2026, offering modest relief to drivers after weeks of elevated spring prices. While the national trend points to a small dip, the familiar regional divide remains firmly in place: West Coast states and Pacific markets continue to post the highest pump prices, while the South and parts of the Midwest and Great Plains offer the most affordable fuel in the country.

AAA’s state-by-state data highlights how taxation, environmental fuel requirements, refinery access, and distribution logistics continue to shape price disparities across the nation.

Gas price today in California

California once again tops the list as the most expensive gasoline market in the United States. Regular gasoline averages $5.837, with mid-grade at $6.064, premium at $6.257, and diesel soaring to $7.530 per gallon. The state’s strict environmental fuel blend standards, high excise taxes, and supply chain limitations consistently keep prices well above the national average despite minor national easing.

Gas price today in Texas

Texas remains among the cheapest large states for fuel. Regular gasoline stands at $3.656, mid-grade $4.116, premium $4.488, and diesel $5.131. Proximity to major Gulf Coast refining hubs and comparatively lower fuel taxes continue to shield drivers from the higher costs seen in coastal markets.

Gas price today in Florida

Florida’s fuel prices sit just below the national average. Regular gasoline is priced at $3.990, mid-grade at $4.439, premium at $4.777, and diesel at $5.487. The state benefits from strong fuel supply channels but still feels the impact of seasonal demand and transportation costs.

Gas price today in New York

In New York, drivers are paying $4.105 for regular, $4.605 for mid-grade, $4.986 for premium, and $5.920 for diesel. Higher state taxes, dense population centers, and distribution expenses continue to keep prices above the national benchmark.

Gas price today in Washington

Washington remains one of the most expensive states for gasoline after California and Hawaii. Regular gasoline averages $5.385, mid-grade $5.625, premium $5.874, and diesel $6.868. Environmental policies and regional supply limitations contribute to persistently high prices across all grades.

Gas price today in Hawaii

Hawaii’s structural reliance on imported fuel keeps it near the top of the price ladder. Regular gasoline costs $5.670, mid-grade $5.914, premium $6.157, and diesel $7.080 per gallon, making it one of the costliest markets for drivers nationwide.

Gas price today in Oklahoma (Lowest in US)

Oklahoma posts the lowest regular gasoline average in the country at $3.376. Mid-grade is $3.781, premium $4.077, and diesel $4.680, offering some of the most affordable pump prices available to US motorists.

For now, while the national average ticks lower, where you live continues to matter more than the overall trend when it comes to what you pay at the pump.
