Of course all the piston airliners routinely ran LOP - but it's
important to remember that over the course of its life, the cost of
fuel the engine burns is significantly higher than the cost of the
overhaul - and thus LOP operation, which can easily save 10-15% for the
same power and speed, can be economically advantageous even if it does
measurably shorten engine life.

This seems like one of the most straight forward and reasonable statements
you've made thus far. That's a good point. A very good point. Have
anything which validates that's the real reason they ran LOP?

Less fuel, cleaner, better internal pressures...all things that make for
BETTER TBO. Some of the airlines were running their radial engines to
3500-4000 hrs between overhauls.

Because LOP saves fuel and keeps plugs clean. That much is proven. It
is a fact that lower combustion pressures are also proven - but how
this correlates to long term engine longevity is unknown.

DUH!!! And you're an engineer? HAHAHAHAHAHAH...
