Good evening Greg,

Further to my comments earlier about my being able to mix Sig Castor oil with kerosene. Initially it went into solution and seemed to be ok. I looked at it today (4 or 5 days laters) and it too had separated. It was sitting in the basement. I tried some lamp oil and eventually seperated out as well.

So, it seems the old wive tale of Castor not mixing with kerosene is true. However, this still leaves Andy's experience of having it mix reasonably well. I think the difference is he is using Klotz Benol which (according to their literature) is a more highly refined castor oil which they describe as "Blends With Methanol Alcohol, Nitromethane, or Gasoline".

So, if we want to use Castor oil in your no ether diesel we will have to use Klotz Benol but that even has some limitations as Andy has noted with regards to temperature and separation.

cheers, Graham in Embrun near Ottawa Canada.
