....it appears then, that all castor oil is de-gummed. [;)]

That's what I'm thinking. Most that have read about competitive fuels know about Lubricin as an additive, but who knew it was castor based? Maxima says they add something to their Castor 927 to reduce carbon buildup. This is probably it. Think about where Sig's castor comes from. They sell Klotz Techniplate which they buy bulk from Klotz.

quote: ORIGINAL: gkamysz http://www.groshea.com/caschem/products/aastandardtds.pdf This is Baker's AA castor oil. I have found that degumming reduces the phosphorus content in the oil. http://www.wsu.edu/~gmhyde/433_web_pages/433Oil-web-pages/castor/castor-oil2.html This is the process of production. I don't believe that first press doesn't have "gum". What the heck is "gum"? I think of the plant resins as gum. Some of these referances seems to call the congealed oil and varnish as gum. So I am not sure what they consider gum. Perhaps the degumming process only refers to the second pressing of the pulp. Notice the diagram has the first pressing going straight to the tank.
