Its not very cost effective to make your own fuel. It cost me about 10 bucks a gallon to homebrewer 50 gallons of 10% nitro fuel containing 20% oil.

I got lucky one day and was able to purchase at selling cost to retailers many cases of fuel from a major glow fuel company. I paid about 7 bucks a gallon for 15% nitro and about 8 bucks a gallon for 20/20.
