Diesel and kerosene are essentially the same but with different tax rates.

Diesel has better lubricating properties than kerosene / paraffin. If
you use raw paraffin or heating oil to run a Diesel engine, you'll
kill the injector pump. If you want to make a habit of this, find a
Diesel (such as an ex-Army multi-fuel engine) that uses a separate
lubricating oil supply for the pump, rather than relying on the fuel
to do it.

"Diesel" can be either tax-free (unheard of in practice), agric diesel
(red, cheap tax), boat diesel (blue, slightly cheap tax) or DERV
(Diesel Engine Road Vehicle, clear, full tax).

I can't see any combustion engine self-generation scheme being cost-
effective, compared to Grid. Even if you went for CHP (Combined Heat &
Power) you need to have simultaneous demand for both heat and power to
make it work out.
