Most enlightening information on Kerosene thanks. I have a similar cut on it as a result of regional differences. Kerosene in New Zealand is just not suitable for Wallas Paraffin burners. I don't know enough about the aviation fuel aspect but here in NZ it may be fraught because of access difficulties.
In fact we have seen many people coming here from the USA, UK and European countries with Wallas Paraffin burners who tell us that by bitter experience that the UK, Europe and some parts of the USA are where the only sources of paraffin are located. Many have tried lamp oil and doctored Kerosene only to end up in our workshop with a smutted up burner pot.
Paraffin appliances have a lower capital cost however the advice is clear - if you are sailing internationally, buy a Diesel burner as you can buy diesel in any country.
