Red Diesel
Red diesel is a fuel used in off-road plant, vehicles and machinery as well as for heating. It is the same technical product as regular diesel, but with a red dye added to maintain compliance to ensure it is not used instead of on-road diesel – red diesel is currently a government subsidised fuel and therefore lower cost. Many industries use this subsidised fuel, in particular agriculture, construction, marine and others. The main users are industries such as:
- Farming
- Construction
- Schools
- Rail
- Factories
- Hospitals
- Marine
- Commercial Fishing
Gas oil/red diesel is commonly used in vehicles such as tractors, farming equipment, off-road plant, forklifts, cranes, power generators, back-up generators as well as boilers.

What is diesel used for? Diesel is an energy-dense fuel that is used to power engines, including cars, trains, boats, turbines, generators and more. It’s mostly used for transportation purposes, while producing a higher mass density than gasoline. Because of this, the same volume of diesel has more energy than a comparable volume of gasoline.
What is the best diesel fuel to buy? The best type of diesel you can use will depend on how you intend to use it. For instance, if you’re using it in your car then you may wish to use premium diesel thanks to its high-performance values. If you’re using it for heating or to power plant machinery or off-road vehicles then you would use red diesel as a rebated fuel.
