There are few ways to make your own fuel. You need to go to your LHS and buy the ingredients. You will need an oil, preferably synthetic. It comes in either high viscosity or low viscosity. You will also need nitromethane and methanol. If your LHS doesn't have the nitro or methanol, you can geth these from a drag racing shop.
Depending on how much nitro you need will determine how much things to buy. Lets say you have a high viscosity synthetic oil, you will need about 18% oil. If you want 15% nitro, then you will need 18% oil, 15% nitro and 67% methanol. If you want 20% nitro, you will have to have 18% oil, 20% nitro and 62% methanol. If you want 30% nitro, you will have to have 18% oil, 30% nitro and 52% oil.
If you get a low viscosity synthetic oil, you need more oil somewhere between 22-23%. You will probably be better off buyng it already mixed as you won't save much money mixing it yourself.
