Just to make abundantly clear, I have said NOTHING about the likelihood of an engine failure at take off, but merely given facts from jet operation (not piston as the linked Lycoming document). CA - you need to speak to Rolls Royce - I seem to recall it was an Avon they test ran without oil for many hours until they throttled it back when I think it failed spectacularly. Like Intruder says, if you don't need to, don't touch it! Certainly power change is as Int says, most likely to be the cause of any stall/surges rather than cruise..
