I was looking through Klotz's site again and looked at the Coxoc. The MSDS says it has a flash point of -18C and a AI temp of 180C. This is very close to ether. The odd thing is it says it freezes at 0C which is above the flash point. It doesn't really say what it is, and at 71USD per gallon, it actually costs more than John Deere Starting fluid. If I could get a small amount of it I'd try it. Nobody seems to know what the stuff really is.

The nitropropane in their Nitro is similar to nitromethane in that it carries oxygen allowing more fuel to be burned.
