Exactly.* Hence the point that the easier you make life for your engine the longer it will make life easier for you, particulary with old-technology, slow-turning*engines like the FL120, aircraft radials, etc.* But the basic premise of the harder you run the shorter the working life of the engine will be applies to everything.* That's not to say a particular engine that is designed for hard running applications will fail prematurely if operated this way--- it will, or should-- operate reliably for whatever length of hard-running time the engine was designed for.
