Since , the British Standard for Industrial Fuel Oils, BS, contains two grades of Gas Oil; Class A2 & Class D. The Class A2. Gas Oil BS Class A2. Gas Oil is a distillate fuel manufactured to give clean burning, maximum heat output and efficient combustion in boilers and off-road. Free download of BS – the fuel specification data sheets for Red diesel, gas oil and Red Diesel / Gas Oil 10ppm Specification Sheet (BS Class A2).

You can also order fuel by filling in our fuel quote form or speak to our friendly fuel experts on 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.

A European Fuel Quality Directive was set out in which stated that as of 1st Januaryall non-road mobile machinery should only contain up to a maximum of 10 milligrams of sulphur for every kilogram of fuel used 10 ppm or 0.

So init became a requirement that all fuel used bx2869 off-highway mobile machinery must comply with EU Ultra Low Sulphur Diesel ULSD regulations, and must therefore contain no more than 2a of sulphur per kg of fuel.

Environmental Legislation has demanded cleaner fuels with less harmful emissions and the British Standard for Gas Oil has changed specification to coass this. EN is the current standard for all automotive diesel fuel sold in the European Union member states.

Back to the news. The red dye contains chemical markers in accordance to Customs and Excise requirements and so its illegal use can be easily detected. This is one of the main reasons why red diesel is lower in cost when compared to road diesel.

Since the change is legislation, and because the majority of Gas Oil used in the UK goes into the Agricultural and Commercial markets to power engines, UK refiners and importers have focused on supplying the UK with diesel which meets the hs2869 possible required European standard EN It has many different names in the UK and a variety of uses. There are two recognized standards of Gas Oil that are currently in use: The higher the cetane rating the shorter the ignition delay. Class A2 gas oil may be used for either application.

The sulphur content of class D diesel is 0. We will expand on this later. For further information on the fuels supplied by Crown Oil, please see our fuel products page.

Gas Oil is a “dual purpose” fuel. So what is my Gas Oil now?

Has Gas Oil specification changed? Class A2 has a maximum sulphur content of 10ppm and is used for z2 road vehicles and equipment, while Class D has a maximum sulphur content of ppm and can only be used for heating or static generators. The Class A2 specification is suitable for both diesel engines and furnace applications whilst the Class D specification is only suitable for furnace applications such as boilers, dryers and roadstone coating plants, but not suitable for diesel engines.

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


Both our suppliers, and CPS Fuels, reserve the right to alter the specification without notice. There are just two of the reasons why there has been a need to significantly reduce the sulphur contents of fuels.

It has a high calorific value heat content and is thus recommended as a boiler fuel in industrial or agricultural installations with pressure jet burners e. Gas Oil supplied from September onwards is winterised.

Gas Oil is permitted for use in Tractors, hence Tractor Diesel, and on Farms, hence Farm or Agricultural Diesel, and is marked with a red dye to reflect this. Gas Oil has a lower cetane rating, so may have a lower energy yield than the DERV vehicle diesel alternative. John Deere, in particular, specify that fuel used within their engines must comply with the higher BS EN white road diesel fuel specification in order to guarantee performance and avoid invalidating warranties.

As Gas Oil is a form of diesel it can be used in diesel engines to provide propulsion or generation. In an update was made in the UK to Clsss Standard BS for gas oil red diesel requiring a dlass of 10mg of sulphur per kg fuel for mobile off-road equipment.

It was introduced to partner the European emission standards as part of the drive for a cleaner environment. The other type of red diesel is class D which is used for sea-going marine vessels, stationary engines, static generators and heating boilers.
