Chinese nitromethane is cheaper than our good old U.S. stuff. If the price keeps going up, probably more folks will repurify the cheaper nitromethane. However, it is important to note that many batches of this nitromethane contains carcinogens (cancer-causing chemicals) at low concentrations. They can be removed during purification and should be. People are doing this to basically save money on their nitromethane. Pretty soon, I fully expect to see another fuel manufacturer claim their stuff is 99.99999785% pure. :-) The best grade of nitromethane in our hemisphere is still the good Angus Chemical Company nitromethane and it has worked well for modelers and car racers alike for a long time. I kind of find it ironic that a company will claim the highest purity of nitro on the planet, and then proceed to put either low amounts and/or lower quality oils in the fuels. That is kind of like snapping at a gnat and swallowing a camel. Some manufacturers have cut the amounts and quality of their oils in their fuels to save money (make more money), in my view, some to the detriment of the modeler and their expensive, well-built engines. I just refer to all this nitromethane stuff as mostly nitromania, with a LOT of heat and hype and very little light on the subject. Nitro is great, it gives you more power, it increases the burn rate of methanol, it gives you a nice reliable idle and great performance. Like Hershey bars, taken in excess, they can give your engine a belly ache. Also remember that many engines will do fine all day on 0-10% nitromethane. Over in Europe and other countries, folks sometimes wonder how the Americans can use so much of this prohibitively expensive chemical and then have to shim the head to lower the compression ratio to even use it sometimes. Just a few reflections from the peanut gallery.
