Diesel fuel is an essential resource for powering a wide range of vehicles and equipment. However, not all diesel fuel is created equal. On-road and off-road diesel fuel are two distinct varieties with their own unique properties and use.
Understanding the differences between these types of diesel fuel can help you make informed decisions when it comes to fueling your vehicles and equipment. In this article, we will explore the key differences between on-road and off-road diesel fuel and help you determine which type is right for your needs.
On-Road Diesel Fuel
This is a common fuel used worldwide, in diesel-powered vehicles. It differs from off-road fuel. Here, we’ll look into the requirements for each type of diesel fuel, and their properties.
This fuel has more regulations and requirements than off-road diesel fuel.
The Different Grades
It is classified into distinct grades depending on its cetane rating and sulfur content. These grades assist the consumers in selecting the fuel that works best for their engine.
The three grades of on-road diesel fuel are;
- Ultra Low Sulfur Diesel (ULSD): This grade has a maximum sulfur level of 15 ppm. It’s formulated to reduce emissions from diesel engines.
- Low Sulfur Diesel (LSD): This grade has a maximum sulfur content of 500 ppm and is applicable to older diesel engines.
- Renewable Diesel: This grade is made from renewable sources such as agricultural by-products, fats, and vegetable oils.
Knowing their grades helps you make informed decisions for your engine and the environment.
How On-Road Diesel Fuel is Refined
It is processed from crude oil. It is heated in a distillation column. This causes it to divide into different parts depending on their molecular weight. The lighter bits, such as diesel and gasoline, are collected on top.
Next, it is sent for hydro treatment. It is mixed with hydrogen and passed through catalysts at high temperatures and pressure. The hydrogen reacts with sulfur and nitrogen in the diesel, removing any impurities and creating a cleaner fuel.
After hydro treatment, it is further refined with filtration and polishing to take away any extra impurities.
The result is a high-quality, low-emissions fuel ideal for use in on-road vehicles.
The Benefits and Drawbacks
Benefits: It gives better fuel efficiency and longer engine life. It’s cost-effective for long-distance travel.
Drawbacks: It contributes to air pollution and greenhouse gas emissions. It’s also subject to taxes and regulations, making it more expensive than regular gasoline.
Off-Road Diesel Fuel
This petrol is a special kind of fuel used for vehicles not allowed on public roads. It has less sulfur and higher cetane compared to the on-road type. It also has a different composition, making it perfect for farming, construction, and marine operations.
Let’s explore the differences between on-road and off-road diesel fuel. Plus, know the benefits of off-road fuel and where you can buy it.
What is Off-Road Diesel Fuel Used For?
It is also called dyed petrol. It’s used in vehicles and heavy equipment not running on public roads. Unlike on-road diesel, it’s not taxed and is cheaper.
It’s mainly used in industries like construction, agriculture, and mining. Tractors, excavators, generators, and pumps require off-road petrol.
The Different Grades
It is available in three grades. High sulfur, low sulfur, and ultra-low sulfur.
High Sulfur: This is the oldest and lowest quality. It was used for vehicles until recently. It has high sulfur content. Burning produces sulfur dioxide, which pollutes the air.
Low Sulfur: This grade has 500 parts per million (ppm) of sulfur max. It was introduced in 2006 and is used for off-road vehicles like farming and construction equipment. Low-sulfur petrol produces 90% fewer emissions than high-sulfur petrol.
Ultra Low Sulfur: 15 ppm max sulfur content. It was released in 2010 and is now the standard for diesel petrol. It is less harmful, more efficient, and better for the environment than high-sulfur diesel.
Differences Between On-Road and Off-Road Diesel Fuel
They both have their advantages. On-road petrol is typically used for vehicles on public roads, like highways. Meanwhile, off-road petrol is mostly used for vehicles in private areas like farms, ranches, and industrial sites.
In this section, let’s discover the differences between them.
Taxes on on-road petrol are higher than on off-road ones. This is because vehicles that use public highways contribute to road wear and tear. Off-road petrol is used for activities such as construction, farming, and industrial activities. Therefore, it is taxed at a lower rate.
Using off-road petrol in highway vehicles is illegal and can result in hefty fines. So, it is important to use the right type and pay the correct taxes.
Sulfur Content Differences
They are different due to their sulfur content. On-road petrol has a lower sulfur content, as regulated by the EPA, at 15 ppm. Off-road petrol, on the other hand, has a maximum of 500 ppm sulfur, since it’s used in types of machinery such as tractors, generators, and construction equipment.
This higher sulfur content leads to more emissions. But, it also provides better lubrication than low-sulfur on-road diesel fuel. This means using off-road petrol in on-road vehicles can result in more wear and higher maintenance costs.
So, it’s important to select the right type of petrol depending on your vehicle or equipment needs and to follow all regulations to reduce environmental impact.
They have similar components and properties. Nevertheless, there are substantial legal distinctions between them. Mainly, these differences relate to their taxation and environmental regulations.
Taxation: On-road type is taxed by both state and federal governments. It supports infrastructural and upkeep expenses. Off-road type is not taxed as it is used for agricultural, construction, and industrial objectives.
Dye: Off-road diesel fuel has a red dye. This shows it is not taxed. Also, it prevents its use on-road, which is forbidden.
Sulfur content: On-road type must follow strict sulfur content regulations to decrease emissions and enhance air quality. Off-road type does not have the same regulations and may have higher sulfur levels.
Consequently, on-road petrol is pricier and its use is more tightly regulated.
Finding a Fueling Station for Off-Road Diesel Fuel
Locating it can be a hassle, especially in remote or unknown areas. But, there are certain ways and resources to find a trustworthy and nearby fueling station.
Google “off-road diesel fuel near me” or use GasBuddy or Fleetio to locate one. Check the National Association of Convenience Stores (NACS) or the National Association of Truck Stop Owners (NATSO) for stations that offer this fuel.
Contact local fuel distributors, agriculture cooperatives, or construction companies to see if they offer off-road diesel to customers. Some states have fuel tax exemption programs for off-road petrol. Look into if your state has this, and what the requirements are.
You can use these resources and strategies to find a fueling station for your needs and keep your equipment running smoothly.
