What is Gas Oil – or Diesel Fuel, as it is commonly known?

Gas oil is one of a family of heavy oils made from the fractional distillation of petroleum. Gas oil can be used for heating or automotive applications, where it is called ‘diesel fuel’. It is also sometimes referred to as ’35 second oil’.

Why is Red Diesel Red?

Gas oil or ‘red diesel’ is the diesel fuel for commercial, industrial and agricultural off-road vehicles & machinery that are exempt from Excise Duty.

Why red? Gas oil for use in vehicles such as tractors, tippers or mowers, is taxed less than the diesel (white diesel) used in ordinary road vehicles. A red dye is added to allow inspectors to identify that it is being used correctly.
