Dallas gas slips under $4 again as diesel eases, but both remain well above last year
Dallas regular gas is back under $4 and diesel eased too, but both fuels are still far above year-ago prices and costly for local budgets.
Dallas drivers got a modest break in AAA’s latest metro price check. As of May 13, 2026, regular gas averaged $3.996 a gallon, slipping back under $4. Diesel averaged $5.046. Both fuels were down 2.3 cents from the previous day, so this is a small easing, not a big drop.
Regular gas is up 0.8 cent from last week, 27.3 cents from last month, and $1.213 from a year ago. For commuters and households, that means the monthly budget pressure has not gone away even though the headline price looks a little friendlier than it did a day earlier.
Diesel tells the harsher story. Dallas diesel is down 22 cents from last week and 44.8 cents from last month, but it is still $1.907 higher than a year ago. That gap matters for contractors, delivery fleets, landscapers, service trucks, restaurants that depend on shipments, and anyone running a diesel-powered work vehicle.
Dallas is also running a touch below the Texas average, which AAA put at $4.009 for regular gas and $5.050 for diesel, and well below the U.S. averages of $4.511 and $5.659. The Energy Information Administration’s weekly update shows U.S. fuel prices remain elevated, which is the backdrop for why local relief is limited.
For drivers, the practical takeaway is simple: the Dallas market is a little cheaper than the state and national benchmarks, but fill-ups are still expensive enough to matter. That affects commute costs, road-trip budgets, and the bottom line for small businesses that burn fuel every day. Local station prices can still vary sharply by neighborhood, so the AAA metro average should be treated as a benchmark, not a guarantee at any one pump.
