Just to kinda add...
Fuel;
Fill your fuel tanks - By filling to maximum and hence reducing the air space to a minimum you have reduced the water vapour to a minimum and increased the fuel dilution of any remaining water to a maximum.
Turning Over:
The caveat on "turning it over a few times" is that the system must reach full temp.
That way moisture is neither in the exhaust system corroding it or in the oil along with incomplete combustion products leading to acidic oil (they are fully vented after a run at operating temp).
90% of your engine wear happens at startup" is absolutely true, but is less to to with "grinding engine parts" and more to do with combustion.
When the combustion gases burn, they form acids which are highly corrosive when their vapours condense. These acids collect in the upper cylinder areas where their temperature is raised above their dew point.
The acids condense and etch the cylinder walls and piston rings. In reality, this accounts for over 85% of engine wear, the other 15% being down to abrasion.
Without a full run to completely vaporise and evacuate these acid vapours you will do a lot more harm than good to your engine.
