Have you tried any hi-octane commercially available

products in an alcohol stove? If so, how does the heat output compare to the "Heet" alcohol fuel people normally use?
And that brings to mind medicinal rubbing (Isopropyl) alcohol -- does it compare?
...Looked up alcohol stove fuels, and found this (
Zen and the Art of the Alcohol Stove). It sounds like the methyl or methyl + ethyl varieties work best in those stoves.
