A byproduct of crude oil, diesel fuel, comes in several different types that can be identified based on their colors. Let’s take a look at the range of diesel fuel colors and what they ultimately indicate.
What Is The Color Of Diesel Fuel?
Many vehicles these days operate on the use of diesel fuel, including heavy-duty trucks. Regular diesel fuel is clear when not combined with any dye. This fuel type is designed for on-road vehicles featuring diesel engines.
While other fuel colors are available, it’s important to note the United States strictly prohibits the use of other fuel colors in on-road vehicles.
Diesel Fuel Colors
Several variations of diesel colors can be used in on-road and off-road vehicles. Some, meanwhile, are designed specifically for heavy-duty equipment.
Clear Diesel Fuel
Clear fuel is the most common type of diesel, designed for on-road use. While the fuel is quite clear, it may be possible to notice a small hint of green, as well.
Available in every gas station, clear diesel fuel, will be taxed just like regular gasoline.
Green Diesel Fuel
Green diesel fuel comes chemically marked with green to show it is for off-road use only. This fuel type is typically used for agricultural reasons.
For that reason, it is taxed at a reduced rate. Green diesel is strictly regulated by law to prohibit any potential misuse.
Red Diesel Fuel
Red diesel fuel is made for off-road equipment only. Using this fuel in on-road vehicles can result in serious legal consequences, including large fines.
Composition is the biggest difference between these fuel types/colors. They are also taxed differently.
Conclusion
Clear, green, and red are all colors of diesel fuel. The biggest difference to understand is that clear fuel is the only fuel type used for on-road vehicles.
