PowerMaster is a real good fuel, it has 1/3 castor oil in it.
FBD, you might want to rephrase that a bit. I do think that Powermaster is not 33.3% oil. The 15% we use for racing is 18% oil. The oil content is 2/3 synthetic and 1/3 castor. So of the total oil content 12% of the fuel would be synthetic and 6% of the fuel castor,
