On-Road Vs Off-Road Diesel: Is There a Difference?

Diesel is a vital fuel source across many industries around the world. Due to state and federal regulations, there are two types of diesel: on-road and off-road. Understanding the differences between the two is integral for any business that relies on diesel fuel. Though chemically they are the exact same, there are a few key differences that they have.

What is On-Road Diesel?

On-road diesel is also known as clear diesel and highway diesel. It is intended for vehicles that operate on public roads, such as passenger cars, SUVs, and small trucks that regularly traverse public highways. It is taxed, so it tends to be more expensive than off-road (dyed) diesel. Clear diesel is easily accessible for on-road motorists. It is the green handle that you see at every gas station. If you used red diesel on the road, you can be heavily fined.

What is Off-Road Diesel?

Off-road diesel is also known as dyed diesel, ultra-low sulfur diesel, and farm diesel. It is intended for vehicles, machinery, and equipment that don’t typically operate on public roads, such as those in the construction and agricultural industries. It is not taxed, so it tends to be cheaper than on-road (clear) diesel. It’s also illegal to use in on-road vehicles, like consumer cars. Unlike on-road diesel, off-road diesel isn’t available for open sale to the general public. It’s must be purchased through a licensed diesel supplier.

What Are the Differences Between On-Road and Off-Road Diesel?

 

1. Color

Because off-road diesel is state and federally tax-exempt, it is dyed red so it is distinguishable from on-road (clear) diesel. Because dyed diesel is illegal to use on public roads,  it makes it easier for governing bodies to identify it for tax-purposes.

2. Taxation

As mentioned above, off-road diesel is state and federally tax-exempt, making it a cheaper fuel source. It is tax-exempt primarily because it is used in non-highway vehicles and equipment, such as farm machinery, construction equipment, and other industrial machinery. These vehicles and equipment do not use public roads, so they do not contribute to the wear and tear of highways and infrastructure funded by fuel taxes. As a result, governments exempt off-road diesel from the taxes imposed on regular diesel, which are intended to fund the maintenance and construction of public roadways.

Here are a couple of key reasons for this tax exemption:

  1. Non-Road Use: The diesel is used in activities like farming, construction, and other industrial operations that do not involve public roadways, so it’s considered fair to exempt it from road taxes.

  2. Support for Agriculture and Other Industries: Exempting off-road diesel from taxes helps reduce operating costs for farmers and industries that rely heavily on fuel for machinery, making these sectors more competitive and supporting economic stability.

In summary, off-road diesel is tax-exempt because it is not used in the transportation network that fuel taxes are designed to support.

3. Their Uses

Diesel powers many vehicles, from every-day trucks, school buses, trains, and even boats. But vehicles that don’t operate on public roads use off-road diesel. Some of the most common industries using dyed-diesel include construction, agriculture, mining, railroad, and carnivals and county fairs. Generators also primarily use off-road diesel.
