NOTICE
Where oxidation catalytic converter is fitted, it is
mandatory to use Diesel fuel with sulphur contents as
given above. Use of any other diesel fuel can increase
the pollutants.
At very low temperature, 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. Ratio for mixing of
supplementary fuel and diesel are shown in the table.
