If you’re managing a commercial fleet, running a construction site, or working in agriculture, fuel is a daily decision. But not all diesel is the same—and choosing the wrong type can lead to legal or mechanical issues.
In this blog, we’ll explain the difference between dyed and clear diesel, when to use each, and how to stay compliant in Toronto.
What Is Clear Diesel?
Clear diesel is the standard fuel sold at gas stations. It’s road-legal and taxed for use in vehicles that operate on public roads.
Common Uses:
- Delivery trucks
- Buses
- Passenger vehicles
- Commercial fleets
Because it’s taxed, it’s typically more expensive—but using anything else for road vehicles can result in fines.
What Is Dyed Diesel?
Dyed diesel (also known as red diesel) is the same as clear diesel, but with a red dye added to distinguish it. It’s not taxedand is strictly limited to off-road use.
Common Uses:
- Construction equipment
- Generators
- Agricultural machinery
- Commercial heating systems
Using dyed diesel on the road is illegal and carries serious penalties in Ontario.
How to Know Which Diesel to Use
Here’s a quick rule:
- If it’s on the road → Use clear diesel
- If it stays on-site or is used for heating → Use dyed diesel
