The latest data from AAA shows the US national average price for regular gasoline at $4.511 per gallon as of May 13, 2026. This is a modest increase from $4.504 on May 12, signaling that upward pressure on fuel prices continues after several days of small but steady gains.
While the day-to-day change is minor, the broader pattern points to a market that is inching higher rather than stabilizing. Regional differences remain stark, with West Coast and non-contiguous states posting the highest prices, while several southern and central states continue to offer comparatively cheaper fuel.
California remains the most expensive gasoline market in the country. Regular gasoline now averages $6.148 per gallon, while mid-grade stands at $6.389, premium at $6.573, and diesel at a steep $7.450.
Texas continues to offer some of the lowest prices among large states. Regular gasoline averages $4.009 per gallon, with mid-grade at $4.481, premium at $4.849, and diesel at $5.050.
Florida’s prices sit slightly below the national average. Regular gasoline is averaging $4.314 per gallon, while mid-grade is $4.763, premium $5.099, and diesel $5.261.
New York drivers continue to pay more than the national average. Regular gasoline stands at $4.593 per gallon, with mid-grade at $5.085, premium at $5.477, and diesel at $5.941.
Washington remains one of the costliest fuel markets outside California. Regular gasoline averages $5.771 per gallon, mid-grade is $6.034, premium $6.280, and diesel $6.815.
Hawaii’s geographic isolation keeps it among the highest-priced markets nationwide. Regular gasoline averages $5.651 per gallon, mid-grade $5.913, premium $6.132, and diesel $7.141, reflecting the cost of importing fuel across long distances.
Oklahoma stands out as one of the most affordable states for drivers. Regular gasoline averages just $3.980 per gallon, with mid-grade at $4.394, premium at $4.694, and diesel at $5.032.
