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.
