RE: Rc Fuel Faq
Fuelman
I've always had a question about whether fuel is mixed by weight or by volume. I have a graph that compares nitromethane percentage by weight vs. percentage by volume. There appears to be a substantial difference. For example, if I mix 15% nitromethane by weight I will only get 10% nitro by volume. Based on this I must assume that the fuel manufacturers will chose to mix by weight, thereby using less nitromethane per gallon for an advertised percentage. It seems that there is a mixed bag of literature on what criteria they use. Some will tell you that they mix by volume while others don't mention it. Your thoughts or comments?
