The OliveLube mix ran well. The Castor mix didn't. What I forgot was that castor and kerosene don't stay mixed at cold temps. I know that the two aren't supposed to mix at all but Benol castor from Klotz does, as long as you're above 60F or so. One thing I recall is that the olive lube seemed to enhance idling for some reason.

---------------------------------------------------------

I found that castor and kerosene don't mix without a certain quantity of ether being present.
I made a mix of 10% ether and 25% castor... and it seemed O.K
The fuel mix was left for a few days and when I came to use it it was very cloudy..... hmmmmm !

I added ether to take it up to 12% and again it looked O.K.... until left for awhile.
I finally found that the fuel mix remained clear when the ether content was brought up to 15%.

I gained the impression that a minimum of 15% ether was necessary in order to use 25% castor oil as the lubricant. This was in the UK in fairly cool weather, warmer temperatures may mean you can get away with less ether in the mix.

I found, after extensive testing, that olive oil does indeed give very good idle speeds.
Mineral oil seems to give very good throttle response
A mix of castor oil, modified olive oil and mineral oil gave me the very best running conditions of all.... with the added advantage of peace of mind due to the castor content

I don't know why olive oil should give such a marked improvement in idling but it certainly does.
Mineral oil gave a much better and instantaneous response to rapid throttle movements.

When mixed together in the fuel the combination of olive oil and mineral oil still gives the best characteristics of both.... very rapid throttling and superb idle..... beats me .... but it works !
