When it comes to fueling your equipment or vehicles, you might wonder: Can you mix dyed and clear diesel? Whether you’re operating in Toronto, the GTA, or rural Ontario, understanding the difference between these two fuels—and the consequences of mixing them—is crucial.
Let’s break it down.
What’s the Difference Between Dyed and Clear Diesel?
In Canada, diesel fuel comes in two main types:
- Clear diesel: Also known as road diesel, this fuel is taxed and intended for use in on-road vehicles like trucks, buses, and personal diesel-powered cars.
- Dyed diesel: Also called off-road diesel or farm fuel, this fuel is tax-exempt and has a red dye added to it. It’s strictly for use in non-road vehicles like construction equipment, agricultural machinery, and generators.
The difference isn’t just the color—it’s about tax regulations and legal use.
Can You Mix Dyed and Clear Diesel?
Technically, yes—you can mix them because they are chemically the same fuel. However, you absolutely should not for the following reasons:
1. Heavy Fines and Legal Consequences
In Ontario, using dyed diesel in on-road vehicles is illegal. If authorities find traces of red dye in your fuel system, you could face:
- Large fines for fuel tax evasion
- Vehicle inspections and penalties
- Business disruptions if your fleet gets flagged for improper fuel use
Regulatory agencies frequently conduct roadside checks in Toronto and across Ontario, so mixing fuels—even accidentally—could be costly.
2. Potential Engine and Fuel System Issues
While dyed and clear diesel are chemically the same, mixing them could:
- Void warranties on some vehicles and machinery
- Cause confusion in fleet management, leading to unintended use in on-road vehicles
- Lead to contamination risks if fuel storage tanks aren’t properly cleaned
3. Problems with Fuel Suppliers
If your business relies on bulk fuel delivery, many suppliers in Toronto and the GTA require clear separation of dyed and clear diesel. Mixing fuels could:
- Violate supply contracts
- Compromise quality standards
- Lead to service refusals from reputable fuel providers
For businesses relying on heavy equipment, trucking, or agricultural machinery, it’s always best to keep tanks properly labeled and dedicated to the correct fuel type.
What Should You Do Instead?
If you need both on-road and off-road diesel, the best solution is:
- Store dyed and clear diesel in separate tanks
- Label fuel containers clearly to avoid mix-ups
- Work with a trusted fuel supplier in Toronto who understands local regulations and can help you manage fuel needs efficiently
