Changing it cold can allow and solids in suspension to settle out and remain to recontaminate the new oil.
Not to mention hot oil flows better.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

The worst is when one takes the car to the dealer or elsewhere for an oil change and it sits for a few hours before pulled in onto the rack.
The engine is cold as is the oil, the tech removes the drain plug and lets oil run for a couple of minutes and replaces the plug.
Adds 5 quarts of oil to a 6 quart capacity pan and calls it a day.
Or possibly worse, puts in the recommended 6 quarts
What could go wrong?

He could forget to put the plug back in, or close the valve it it has that fancy valve. He could forget to put in oil, or the wrong oil. He might or might not replace the filter.

Usually cold.
I always figured with it cold, the oil had time to drain back to the pan from the upper extremes of the engine giving a more complete drain.
Rarely am I in a rush, so, I'll pull the plug and let gravity do its thing for a half hour or longer.
I've always done it this way and have never had an issue.

dump 1/2 qt in the top to flush the pan a bit and thats about all I can do. good idea that I have wondered about for awhile & recently I had oil pan out/leveled (tho most are changed with the front jacked up) I was surprised at the amt of dirty oil left in the bottom (& extended oil changes are getting more common).
