What has worked great for me is mixing my own. I buy 5 gallons of pure methanol for $23 and 1 gallon of Sig castor oil for $31 shipped and mix it 80% meth/20% oil (no nitro) and run it in the following:
OS 40FP, OS 40LA, Super Tigre 40, Magnum XLS46 and Rossi 45. I add a splash of Acetone to aid in the idle and run my engines with a Hot plug (OS 6 or OS 8). So for less than $60 I get 5 gallons of glow fluel. You can buy pure methanol from any company that carries oils or diesel fuels or any high performance race shop. I cant tell the difference between my mix and any major brand.
