I also ran an old SuperTigre .51 in which I had installed a new Frank Bowman ring, it ran fine. That's all I've run Saitos and an OS or two on for about 5 years.
For one I said that castor is thicker than most synthetics. But since the same engine will do fine with castor as well this is no proof that one is better than the other. Yes most engines will do fine with synthetic. With this type of testing you would have to run hard till the same model of engine is worn out on both oils.
