Okay, I've got one for ya...
 

I want to work for a man from Georgia (the country, not the state), who was a car enthusiast, and European car collector. He insisted I’m driving well out of his way to the relatively short distance back and forth to work, because he said that it didn’t give his engine enough time to get up to temperature taking the direct route. He said that every time you started your engine, it should be driven until it reached warm up running temperature for the sake of its longevity, before it was turned off, and apparently idling after a short trip wasn't sufficient. Is there some engineering logic that would lend credence to his practice?

If one doesn't run the engine long enough then moisture in and under the valve cover will mix with the oil
It will create a sort of paste that looks like mayonnaise.
When the engine runs long enough to heat up the moisture, it reduces this chance of making this paste.

Ah, yes. That makes sense. But for what length of time would you have to run the engine to expel that vapor?

Run for at least ten to twenty minutes when engine is warm

It is a known fact that 80% of engine wear takes place when the engine is cold. That means below operating temp which is about 140 degrees F

That maybe true but does little to answer the original question. A commuter wants to go from A to B and B to A about 200 to 300 days a year. Will extending the commute to 20 minutes or so result in more commutes for the life of the engine?
I suggest more frequent oil changes with high quality oil and an extended drive once a week. This should take care of the condensation issue. Or best: get an electric vehicle.

Trivia question: where does this water in the oil and water paste come from anyway?

Since you asked,
How's this?
Depending on the ambient temp, Of which the ambient temp of Georgia is unknown, also the vehicle starting temp of which is unknown, we can only hope the vehicle has some indication of engine temp on the dash and bla, bla bla. By the way, , Happy Easter Guys !

The air moisture and it gets sucked into the engine in one way or another.
Happy Easter

How is this: When you combine hydrocarbons with oxygen you get carbon dioxide ( CO2) and dihydro oxide (H2O). So, our ICE's are really making power with steam that is generated in the combustion chamber.

Happy Easter to you guys also!
