Good thought. Scot furnished a breakin log. RPM vs head temp. The only fuel info he listed was 10% nitro and 50/50 oil. Meaning 50% synthetic and 50% castor.
Yes this is what you want if you can get a fuel with 20% oil 50/50 mix that's what want to buy if not 5 oz. of castor added to a gallon will bump the oil content by 3%.
