Dyed Diesel Fuel vs. Regular Diesel – What’s the Difference?

Did you know there are three types of diesel fuel?
Off-road Diesel
Off-road diesel doesn’t have state and federal taxes. Sometimes it’s called red diesel, alternative fuel, red fuel, off-highway diesel, or farm diesel. And, it’s not intended to be used for vehicles driven on the road. The diesel color is red for identification, and red dye is only for use off-road.
For example, in construction red dye fuel would be used for heavy equipment like:
| Cranes | Earth movers | Caterpillars |
| Loaders | Backhoes | Excavators |
| Compactors | Trenchers | Cranes |
| Rollers | Scrapers | Forklifts |
Truck Diesel
This is what long-haul truckers use. In some states, the pumps have a “tax-exempt” label. In that case, you need a valid tax certificate posted on the vehicle. Otherwise, you can get a big fine.
The fuel itself is the same as automobile diesel, also known as on road diesel.
Automobile Diesel
This fuel is for cars, SUVs, and regular trucks. Automobile diesel is the same as truck diesel, but the pump nozzles are smaller.
If you’re wondering what is auto diesel, it refers to diesel used in everyday on-road vehicles.
