It is not an exact corollary, but you can use kerosene in an eberspacher heater, and it will burn much more cleanly - as red diesel in UK does not have a lot of the fancy additives used in road diesel, it can burn very dirtily and clog up the jet, a brief use of kerosene instead will clean it up nicely.

You can use kerosene in a diesel car as well, but it needs some additional oil in it otherwise the pumps complain.

I remember on my Grandparents farm in the 50s, the old tractor was actually a kerosene burner, started on petrol, and once warm turned over to kerosene (much cheaper then)
