You have to consider the smaller operating range when running LOP. Small
changes in altitude, temperature, or pressure will wider fluctuations in
temperature when running LOP as opposed to ROP. We would all like to think
we keep the engine perfectly leaned, but over the 2000 hours on a typical
engine, how many times does the average pilot let the temperature drift a
little before catching it. How long at 25 or 15 LOP before you shorten the
engine life.

Well, I hope you've kept adequate re$erve$ for a top overhaul in addition to
your early MOH.
