It has some minor drawbacks that have not been an issue with my using it for past 7 years on my motorized bikes.
It flashes at 420 deg F. The flash point is the lowest temperature at which a liquid vaporizes into a combustible mixture. The higher the flash point, the longer it is a liquid lubricating your engine. In addition, once castor burns, it forms an even better dry lubricant providing even more overtemp protection!
BTW, Amsoil interceptor flashes at 176 deg F and Amsoil saber at 214 deg F.
I ran Maxima 927 and my own personal blended castor/synthetic oil blends in excruciating conditions that turned my cylinder head read hot, discolored the metal on all of my engine components without the engine seizing and allowing another 3+ years of abusive use before I sold the bike to someone else.
This is a weird reply, but since childhood running Dad's model airplanes, I have always LOVED the smell of castor oil based fuel engines
An Amsoil user, I might spike my tank with a little Maxima just for pleasure
