GasBuddy analyst Patrick DeHaan said President Trump's executive order easing
limits on dyed diesel is unlikely to materially reduce diesel prices across most
U.S. regions. Most states still ban dyed diesel for highway use, the move
appears to defer rather than waive federal fuel taxes, and it does not increase
physical diesel supply. Diesel futures and refinery crack spreads should remain
driven by Middle East crude flows, low inventories and emergency stock releases
rather than this tax change. A few states that shift to dyed diesel could
tighten non‑road fuel availability during harvest and raise local prices, while
potential deferred tax bills may deter fleets from switching and limit demand
transfer. A full federal diesel tax suspension would require congressional
approval and, even if passed, would likely have only limited nationwide impact.
