Well, racing castor is still castor at heart that's had stuff done to it or added to it. If it hasn't had anything done to it or added to it, then there's nothing more special about it than the stuff that makes you poop easier. Heck, they could out the word "racing"'on the laxative bottle and sell more of it?

Benol isn't regular castor is the point I was trying to make. It's expensive that has other stuff added to it and its chemically changed from the base oil. Mix it with gas for your go kart, not model engine fuel. IMHO.
