RE: disposing of nitro fuel?
Old methanol-nitro fuel works in your gasoline tank of your car or truck. Often times we experience water in our fuel tanks. We go to the auto parts store and purchase "dry gas" to rid our fuel tanks of the moisture we may have acquired at our local gas station or in the northern climates; the heating and cooling causes the air vapor in our fuel tanks to "sweat" and deposit a very smallamount of water in the bottom of our car's fuel tank.Eventually, this water accumulation can become a problem. "Dry-gas" is methanol in a little bottle that the auto parts stores charge alot of money for. Old model airplane methanolfuel even with nitromethane and castor oil/syntheticoilin it works great for removing any accumulation of water ina fuel tank. The oil doesn't seem to foul the spark plugs and does a great job of cleaning the fuel injection system. My wife's DTS Cadilac Deville was running a little rough a couple of years ago. A pint of old airplane glow fuel fixed it right up!
If you have poison ivy growing around the yard; old fuel takes care of it in a couple of days.
