So I was trying to figure some random stuff out, trying to figure out something other than gasoline to supplement inject into an engine in a stand alone with nitrous other than gasoline. I know there are a bunch of things I don't know about chemistry, but I have a couple questions before I can even proceed. I took Octane and balanced the equation and found its change in enthalpy during combustion, then I found the change in enthalpy of Decane the same way. I found Decane to have a higher change in enthalpy during combustion, please correct me if I am wrong. But, i think that means that Decane has more energy per mol. Then I used a reference of -1X10^11 kJ to see how they compared for a certain amount of energy. I used the molar mass of Octane and Decane to convert these to kg used for that amount of energy. Since the molar mass of Decane is higher than Octane I found that you need less octane in kg to make this amount of energy, by quite a bit I might add. So my conclusion is that it would be a waste of time to try to use Decane. As if I even know where to find it or enough about chemistry to actually get everything working correctly. Please correct any mistakes I've made in my logic here. I'm completely self taught in Chemistry. Thanks.
