What is Red Diesel?

Red diesel, Gas oil, 35 second oil, rebated diesel are terms used to describe the fuel that is used in off-road vehicles and machinery. It is essentially the same as regular diesel you might use in your car but with a red dye added to help prevent illegal use.

This dye ensures that only permitted industries can use it, as it is subject to lower fuel duty compared with regular white diesel.
