Jezmo- I didn't find the comments you are talking about, or I would have removed them. I can see the disagreements but they seem to be okay at the moment. We all get worked up over these sorts of subjects it seems. I hope we can keep it civil and friendly no matter the disagreements.

Red B- I have not seen any proof or claim that any synthetic oil protects like good old castor, newer European oils or not. The bottom line still is that synthetics burn to ash at lower temps than the point where castor provides better protection with 'varnish'. The varnish is protective whereas ash is not. Also, castor probably still provides far better rust prevention than synthetics. Myself, I use a blend of synthetic and castor.
