Trump's Red-Dye Diesel Order May Offer Limited Relief, Experts Say

President Trump signed an executive order Monday evening that permits drivers to use tax-exempt red-dye diesel, a move intended to alleviate the financial strain on Americans. However, experts suggest the impact on pump prices may be minimal due to several logistical and regulatory challenges.

Red-dye diesel is chemically identical to standard diesel fuel but is colored red to signify its tax-exempt status. It is typically designated for off-road agricultural equipment, such as tractors. While long-haul truck drivers could potentially achieve significant savings by using this cheaper fuel, potentially passing those savings on to consumers for goods like groceries, experts point to several obstacles.

Patrick De Haan, head of petroleum analysis at GasBuddy, estimates that only a small fraction of truckers, possibly one in 100, will be able to utilize the tax-exempt fuel because it is not widely available at typical fueling stations. "The problem, first of all, is that dyed diesel is a specialty product. Generally it appears in rural areas where there are many farmers, not at gas stations," De Haan stated.

CNRG Fleet, a fueling management company, indicates that off-road diesel can be found across the country, but refueling locations are often dispersed and uncommon in urban areas. For instance, the closest readily available red-dye diesel station to New York City is in North Bergen, New Jersey, with no such options on Long Island.

Ramanan Krishnamoorti, vice president for energy and innovation at the University of Houston, noted that many consumers are unaware that red-dye diesel is the same as ultra-low sulfur diesel, apart from the added dye. "So adoption becomes more challenging," Krishnamoorti said.

During a campaign rally, President Trump asserted that the average trucker would save over $100 per fill-up and that farmers would save millions, predicting a substantial reduction in the cost of all goods, including groceries. This is because a large portion of consumer goods in the U.S. are transported by diesel-powered trucks.

National average diesel prices reached $6.32 per gallon on Tuesday, a 71% increase from $3.68 a year ago, according to AAA. De Haan suggested that some states might see a diesel price reduction of up to 60 cents per gallon due to the executive order, though this could vary significantly by state.

Krishnamoorti cautioned that the rollout's effectiveness "all depends on how fast this gets adapted," adding that he anticipates "a whole bunch of states interjecting and indicating federal overreach." Executive orders do not automatically supersede state laws, leaving states with the discretion to decide whether to waive taxes on diesel fuel, and tax rates for red-dye diesel differ across states.

The varying tax status across state lines could discourage long-haul trucking companies from adopting red-dye diesel, as drivers might face penalties in states that do not waive the taxes. A nationwide suspension of the diesel tax, which De Haan estimated would save 24.4 cents per gallon in every state, has not been proposed by policymakers.

"Truckers who don’t cross a state line may be able to use this. Farmers and construction companies are already using dyed diesel," De Haan commented. "The announcement is very loud but the potential impact isn’t really a needle-mover."

Further questions arise regarding the executive order's language, which authorizes highway use of tax-free dyed diesel but states it is "deferring the federal diesel excise tax through the end of the year." It remains unclear whether these taxes will be fully waived or if a bill will be issued later.

Drivers might also be hesitant to use red-dyed diesel due to the potential for residual coloring in their fuel tanks. After the temporary waiver expires, truckers who have used red-dye diesel could face scrutiny if exhaust emissions indicate the use of the dyed fuel.
