Castor is added because it offers a higher protection over synthetics, either here in the U.S. or Europe. Some European oils have better cling over some of the more popular glow fuel oils over here, but castor is still the best for hot and lean runs. I have yet to see any synthetic that survives the heat levels of castor, or more importantly, still provides the same protection when overheated. The varnish people mention about castor is the protection when you need it most. A blend of both castor and synthetic is the best bet. I've always thought it a shame that nitro is heavily taxed in some places. There are a couple of countries in Europe where nitro is priced comparable to the U.S., but I forget which now. There were some interesting prices posted about a year ago.
