Sulphur was identified as one of the most harmful components of Gas Oil, but was historically needed as a lubricant within the fuel. Since white road diesel DERV was already ULSD compliant at this time, it is often believed that the specifications for red diesel and white diesel have been identical since the regulation change, but the potential for the two differences — cetane and bio components remain. In the UK it was found that some modern tractors suffered from poor performance because they were running Class A2 Gas Oil whereas they were designed to operate on fuel that met the higher BS EN white road diesel fuel specification.


A lot of the confusion around Gas Oil, and the variety of different names, has come both from clsas variety of different uses, and changes to product specification over the last few decades.

It has many different names in the UK and a variety of uses. Road fuels, Petrol and Diesel have high duty rates applied to them, but other non-road fuels have lower or zero duty rating applied.

The other type of red diesel is class D which bs2896 used calss sea-going marine vessels, stationary engines, static generators and heating boilers. There are just two of the reasons why there has been a need to significantly reduce the sulphur contents of fuels.
