That is a question that cannot be solved. Companies fuel vary to much to awnser your question. The Make up of fuel is usually the same: nitromethane, methanol, and some sort of oil wether it be castor, synthetic or a mixture of both. some companies run hardly any castor and some companies hardly run any synthetic. some companies run a 1/2 mixture while some companies run a 1/4 synthetic or a 1/4 castor. you see it varies to much to actaully tell someone what the best fuel is. Car engines vary alot also. Some have more ports then others and some arent as good quality then others. beilive it or not, engines sometimes have a fuel preference.



Here is what i would do if i were you. try out different fuels and see what you like best. make note wich one has the best power and provides sufficient cooling. I have done this myself. I found that i can run cheap "airplane" blend fuel in my engines just find so that is what i will continue to run. Im not going to try and tell you too buy the airplane blend, just find what you like and stick to it.
