I was not aware that the oil sump in internal combustion engines had been moved to the top of the engine.
I reject the premise that "warming up" was the result of "fuel mixture issues."
There is no way to drive away at idling speeds; anything above idling speed increases wear on the entire engine, before oil distribution throughout the engine takes place.
The rule of thumb was that 50% of engine wear was at start up.
A lot was dependent on oil quality and time between starts controlling clingage to metal parts.
Do you have an oil gauge? Seconds after the gauge shows full pressure you have full flow.
Modern automobile engines have computers to indicate when to change the oil which is dependent on how the engine was used.
Longer idle periods will result in the computer indicating that your oil will need changing sooner.
