I want to mix up some nitro car fuel (I finally broke down and bought a1/8th scale nitro buggy to play with in the back yard when I can't go flying).
I have some gallons of glow fuel that are 23% nitro and 22% oil. That would leave 55% methanol. Breakdown by ounces (volume) would be 29.5oz of nitro,28oz. of oil and 70.5oz. of methanol = 128oz.
If I add 64oz. of methanol to a gallon of this fuel, I end up with the same29.5oz of nitro, the same 28oz. of oil, and now 134.5oz. of methanol for a new total of 192 oz. By my calculations, that would give me a decent car fuel of 15.4% nitro, 14.6% oil, and 70% methanol.
I remember reading something about the possibility of fuel being mixed by weight versus volume. If that's the case, I'm wondering how far off my calculations would be. The car fuels I see on Tower are offered in 10% oil "Pro", 12% oil "Race", and 14%-18% oil "Basher" mixes. My 14.6% oil mix would put me somewhere on the comfortable side of the oil range if I'm figuring correctly.
Thanks for any information, desmobob
