Hi Ryan, check following link for guidance … http://www.rotaryaviation.c= om/faq.html

General consensus is maximum oil temperature into engine, af= ter oil cooler is 210F – this is to protect rotor oil seals.

Suggested maximum continuous operation <200F for both oil= (inlet) and water (block) temperature.

My suggestion would be 160F to 190F for both as normal cruis= e operating temps.

Is there some guidance somewhere indicating the approp= riate temperature range?
