Fuel-industry groups are urging retailers to wait for clearer rules before expanding red-dyed diesel sales following President Trump’s new executive order.
Their concerns include taxes that could come due later, differing state restrictions, and the practical problems of supplying the fuel.
For diesel RV and tow-vehicle owners hoping for cheaper fill-ups, those warnings raise a practical question: will their usual fuel stop offer it?
Why fuel sellers are hesitating
In an October 6 alert published by FUELIowa, Energy Marketers of America (EMA) advised members to wait for federal and state guidance before changing their dyed-diesel sales, tax collection, or compliance practices.
EMA said the order itself does not authorize highway sales or use. Eligibility and conditions depend on Treasury’s implementation.
According to NBC News, fuel-marketer association SIGMA and truck-stop association NATSO also warned members about participating.
“We do not expect most reputable diesel retailers and fuel marketers to do this,” the groups said.
Their concerns included continuing tax obligations, potential liability, and residual dye remaining in tanks and fuel systems after the temporary relief ends. That warning reflects the associations’ expectations, rather than confirmed decisions by individual fuel chains.
Delaying the tax does not erase it
The October 5 executive order directs Treasury to determine its authority to postpone certain diesel-tax payments and identify eligible taxpayers. It also calls for an IRS announcement providing specified penalty relief for highway sales and use of dyed diesel from October 5 through December 31, 2026.
However, the order leaves the underlying tax obligation in place. Treasury is directed to consider ways, including legislation, to eliminate that obligation.
“Deferral is not forgiveness,” EMA warned. Fuel marketers could be among those responsible for paying the tax when the deferral ends.
Treasury’s implementing guidance must identify who qualifies, the conditions of relief, and the payment deadline for postponed taxes. As of the morning of October 7, we had not located that guidance in our checks of Treasury and IRS announcements.
Getting dyed diesel to the pump brings complications
Even with clearer tax rules, offering dyed diesel widely would require suitable equipment and supply arrangements.
Roll Call reported on October 7 that SIGMA questioned whether dedicated equipment and fuel supplies are available to sell it at scale. An agricultural business that already stores dyed diesel faces a different situation from a retailer introducing it for highway customers.
State rules add another complication. A driver crossing state lines could purchase fuel under one state’s relief provisions and still face restrictions or tax obligations elsewhere.
Federal tax-penalty relief also leaves separate environmental requirements unresolved, EMA cautioned. Retailers need clarity on what they can sell, to whom, and under which conditions.
How much could drivers actually save?
Truckers’ representatives are also questioning the potential benefit. NBC News reported that Todd Spencer, president of the Owner-Operator Independent Drivers Association, said wider use of dyed diesel would provide only “minimal relief.” He said a more stable fuel market is needed to bring costs down over time.
At the federal diesel-tax rate of 24.4 cents per gallon, the tax amounts to $12.20 on a 50-gallon purchase. Any reduction at the pump would depend on the relief that applies and what the seller passes along. State tax relief could affect the total, but it would depend on the rules in that state.
Postponing payment also does not make that amount a permanent saving. Under the order, deferred taxes remain payable unless the obligation is subsequently eliminated.
What RV owners should watch for next
For RV owners, the next useful developments are federal implementation guidance clarifying eligibility and tax responsibilities, followed by announcements from fuel sellers about availability.
Personal RV eligibility remains unconfirmed in the materials we reviewed. Until those details are clearer, travelers should not count on buying red-dyed diesel at their usual stop or build a particular saving into their trip budget.
