ENgine oil doesn't burn well - hence blue smoke with knacked engines!!
You'll find it blocks the injectors and combustion chambers up (worse on a indirect diesel - like the old Transit engine (2.5 york)) and will wreck the pump as its miles to thick!

Because kerosene is slightly more viscous than diesel (28 sec instead of 32 if my memory serves right) so the engine oil brings it back up to the right viscosity.
Kerosene is also less lubricating than diesel so the added engine oil aids lubrication of the pump.
