"The first point to bear in mind is that a conventional diesel fuel with kerosene and ignition improver should not be used in these engines—quite apart from the starting difficulties which will be experienced, serious damage will result if this advice is ignored."
I dunno Earl, perhaps the extra calorific value of kerosene would over stress the engine?
