LPG avg 46930
Petrol avg 44750
Kero avg 43990
Diesel avg 43320

Kero(jet fuel) would be better than diesel - it's also a lot thinner.

That interests me too. Would it have a tendency to gum up the works at all?

Obviously the higher the amount of kero the more likely it is - in some countries the petrol you buy at the pumps is doctored as much as 60% kero.

Ideally you want 2 tanks - start on pure petrol - switch to the petrol/kero mix - and then pure petrol again before shut down.

Can Turbodiesel give us any clues as to how it's done - or is it secret? Do Barrus sell conversion kits? Are there any major problems with engine reliability?

Sadly, I'm old enough to remember petrol/parrafin engines - I always thought they smelled rather nice, though I think they used something called Tractor Vapourising Oil. TVO.

Woe betide you if you let them stop without switching back to petrol - oiled up 2 stroke symptoms plus.

Probably not allowed to say how its done!!, and no we dont sell it as a kit!!. The engine looks pretty identical to the that standard production engine thought. The engines are still on Trial at the minute so they are having lots of hours put on them by various select people on boats. I just go out and check them every 100hrs or so.
