If you know anything about engines and oil you also know that dilluted oil, or thinned out with petroleum, decrease its lubrication capabilities up until the temps get high enough to ventilate the petroleum.

When the engine is at lower temperatures, a lower viscosity oil is desirable to keep the top end lubricated.
That is the purpose of the fuel, to lower the viscosity. As the temperature rises, the fuel is vaporized and vented leaving the oil at its pre-mix viscosity.
I honestly do not understand the point you are trying to make.

It was a compromise to improve reaction time.

It is a measure to
reduce wear on the engines, too.
Why do think they recommend pickling over ground starts and runs for aircraft engines today that experience more than a few weeks without being flown?
The best thing you can do to keep an airplane healthy is fly it. One of the worst you can do is ground run it up over and over without flying it.
That will cause corrosion and reduce the engine life faster than just letting the airplane sit.
