Gas Oil

Gas Oil is a distillate fuel manufactured to give clean burning, maximum heat output and efficient combustion in boilers and off-road diesel engines. It is a 'rebated' gas oil, (reduced rate of excise duty) and as such is dyed red and contains chemical markers in accordance to Customs and Excise requirements, to prevent its use as a fuel in road vehicles.

Gas Oil exceeds the latest requirements of relevant British Standard Specification BS 2869 Class A2 and D. Fuel properties are seasonally adjusted to maintain good low temperature operability.

Gas Oil is a "dual purpose" fuel and is recommended as a boiler fuel in domestic or light industrial installations with pressure jet burners and as a diesel fuel for off-the-highway equipment such as stationary diesel engines, farm tractors, construction equipment, railway and marine engines.

Product grade switch over Winter to summer grades Gas Oil 10ppm and Diesel EN 590 when and from where? 2018/2019

The switch over from Winter grades to Summer grades at the terminals was from 16th March

Cold Filter Plugging Point (CFPP)

The cold filter plugging point for gas oil is -4 degC for summer and -12  degC for Winter.

For Diesel, the cold filter plugging point is -5 degC in summer and -15 degC for the winter.

Cloud Point

The Cloud point for gas oil is 3 degC in summer and -2 degC in Winter.

The Cloud point for Diesel is 3 degC in summer and -5 degC in Winter.

The switch overs are as below.

Summer(S):

16th March to 15th October Ex Refinery

16th March to 31st October Ex Road Terminals

Winter(W):

16th October to 15th March Ex Refinery

1st November to 15th March Ex Road Terminals

Note that the switch over from Winter to Summer is the same date for both refinery and terminals. That is because winter grade is fine for summer use, it is only the reverse that can cause an issue.

Note also that with ambient temperatures at 0 degC (as across the UK recently), both fuels would look cloudy (see above cloud points for summer) but there should not be any associated filter blocking problems.
