I live close to Indianapolis In. racing capital of the world. Finding the ingrediants here are easy if you can buy large amounts. Like 4 drums of nitro at a time. Mixing my own fuel is just plain fun. If you fly alot it is worth it. Dragsters use 11 gallons of fuel in 1/4 mile ,that is 44 gallons to a mile. Engines have to be rebuilt every 1/4 mile. The simple fact is nitro kills engines and eats internal metal. The less you use the longer your engine will last. Nitro is expensive and should't make up for and under powered plane. Get a bigger motor. If you gather all the recommended engine manufactures fuel list it would bring you to conclude this. 20% oil of a blend like 20 /80 and 5 to 10% nitro. I still am not convinced 100% synthetic is good , so humor your engine and warranty with alittle castor oil..
