Less than a month before the midterm elections, the price of fuel is becoming a powerful electoral question.

This week, President Trump released a decree aims to reduce costs for frequent diesel users by making a type of fuel called “dyed diesel” more accessible through the end of the year.

Could this reduce the cost of diesel? Let’s go.

Why is diesel so expensive right now?

Prices of all kinds of oil products have risen this year because fewer ships are passing through the Strait of Hormuz and carrying crude to refineries around the world – but the diesel supply chain has been particularly hard hit. Ukraine’s recent attacks on Russian refineries have knocked many of them offline, and Russia has cut its diesel exports. China too.

Added to this is a limited supply of diesel – a fuel that powers much of the industrial supply chain.

Its price has therefore soared; the American average for a gallon broke a record from $6.52 a few weeks ago. The price has fallen a bit since then, but a gallon remains about $2.60 higher than this time last year, according to AAA.

Analysts say when diesel prices rise, inflation will likely follow. Diesel powers much of the industrial supply chain, from agricultural equipment to trucks moving goods from warehouses to grocery stores.

What is tinted diesel?

The “dye” part means: red dye. “Red-dyed diesel is diesel that contains red dye. That’s it,” said Will O’Neill, senior analyst at S&P Global Energy and a fan of all things diesel.

Chemically, this diesel is almost identical to the regular type found at most gas stations. But it’s a different color because it’s used and taxed differently.

Red dyed diesel is only for off-road vehicles, primarily agricultural and construction equipment, such as a tractor used in a field. It is exempt from federal tax 24.4 cents per gallon on commercial diesel.

Drivers are not supposed to use it in vehicles traveling on highways. People who do so are subject to an IRS penalty – either $1,000 or $10 per gallon, whichever is greater.

The red color makes it easier to catch someone who has filled their tank with the wrong substance. Using red-tinted diesel is “effectively a form of tax evasion,” O’Neill said.

But the new decree stipulates that tinted diesel will be authorized on motorways until the end of the year. The IRS will not penalize anyone who uses it.
