I would mix 1part glow fuel and 1 part heat(metanol) this would make your glow fuel 7.5% nitro and 9% oil then I would go ans take 1 part of this mixture and mix it with 2 parts 91 octane gasoline; at the end you will have aproximately 2.5% nitro, 3.333% oil, 27% methanol and 66.6 % gasoline which wil work fine with the engine. but remember to mix the heat and the glow fuel first, one question though is Heat pure methanol or does it have other ingredients in it, because these other ingredients may cause the fuel to split just my guess, but go ahead and make a smal batch and see wath results do you get.
