Bob:
Sorry if I misunderstood. I don't know what it means when you say "lean ROP or LOP to >60 ROP if necessary... depending on power". Perhaps you can clarify. But my 2 POHs were clear: at cruise run only 2+ divisions (or over 50 degrees) rich of peak EGT. No ifs ands or buts. Just like Tom (OSCARDEUCE) says. Your point 4 (although unclear) suggests something different. And your point 7 is different.
BTW, I'm not saying that it is technically unwise to operate as your points 4 and 7 indicate. I think that there is enough data out there showing that at low power settings it's hard to damage the engine by operating close to peak EGT or even lean of peak EGT. It's just that you're likely to have any warranty claim nullified by departing from the POH and that the POH recommendations (2+ divisions rich of peak EGT) leads to good combustion results (i.e., clean plugs).
Finally, kudos to Kevin for removing this topic from the old thread and starting a new one.
