I, for one, would not use it. I sat in a presentation by Evan's coolant
where they talked about its use and advantages. There are some, but mainly
for engines that can benefit by running hotter. (Over the road diesels). The
heat transfer characteristics are less desirable, lower heat capacity, lower
thermal conductivity, higher viscosity than water/ethylene glycol mix.

It will work, but you will be closer to the ragged edge on the temperature
limits on the rotary.
