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.
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.
