Fuels :
High speed diesel conforming to IS 1460 or DIN 51601 or
equivalent is recommended to be used as fuel.
At very low temperatures fluidity of diesel may become
insufficient due to paraffin separation. It is therefore,
necessary to mix supplementary fuel with summer or winter
grade diesel. The supplementary fuel to be used is kerosene
or aviation turbine fuel
