U-Haul is the one major chain that publishes a live per-gallon refill price: its propane results pages list each location with its own current price. Each price above was read on that page on Oct 30, 2026 and carries its source link and check date. U-Haul prices are live and change — a verified price here is shown fresh for 30 days, visibly aged after that, and demoted to “last reported” after 90 days (see the methodology). Confirm the current price before you drive.
Propane refill in the Dallas–Fort Worth area
Dallas–Fort Worth has 3 verified refill prices, every one read from U-Haul's own propane results pages on Oct 30, 2026. The lowest is U-Haul at Ferguson Rd in Dallas, TX at $4.15/gal (+ tax).
Coverage so far is the Dallas side of the metroplex (Dallas and Garland). No Fort Worth-side results page was opened in this pass, so no Fort Worth price is shown — Fort Worth stations will be added only when their prices have been read the same way.
