How to use castor oil??

[Nomad]

I have read a little about the use of castor oil in the mix, I think I like the smell of burned castor oil, reminds me of the small airplane engines I used to run on my models. How would I mix it to be useful in the gas oil mix?.... could I use it instead of regular 2 stroke synthetic or in combination with it?... what are the benefits of using castor oil?....

thanks.

you can buy synthetic/castor oil blends. i blend my own, about 50/50 with the honda synthetic 2-stroke and the maxima927 castor, both available at local motorcycle shops. i read somewhere that as the castor burned up it was still a dry lubricant, espesialy at extreme tempuratures such as in the ht motors. i dont know maybe i just like the smell of burning castor too.

I have some 100% pure castor oil from the health food store, could I use that in a 50/50 mix or just add a half ounce or so for the smell effect?

It has to be "de-gummed" castor, and it has to be the type that mixes with gasoline, not alcohol.

Don't run it straight. Blending with synthetic oil is fine. Figure out what ratio you want to run over all and then back into it with a small amount of castor.

FOR EXAMPLE: If you decide on 32:1 overall. This is 4 oz to make up the gallon (128 oz) of gas. Use .5 oz castor and 3.5 oz synthetic oil.

I would say whatever blend you decide on, keep the castor less that 1 oz per gallon in your blend or you will foul your plug and build up crud.

Castor oil mixes well with the white lightning fuel, that being Cohlman lamp fuel. My friends over at the local air strip sware by it in their weed eaters as well. Nothing but clean vapours and no blue trails.

Yep,

The guys at my local flying field have been using it in their R/C planes for years.
