How long does it take for the oil to drain out of an engine completely?

As a general rule, a typical oil change can take from 30 to 45 minutes to complete. This includes draining the old oil, replacing the oil filter and adding the new oil to the engine. There are a few options available when it comes to getting the oil changed in your vehicle.

Should I warm up my engine before changing oil?

The five-minute rule is a good one. You warm up the oil so it’s less viscous and it flows better. That way, less of the old oil remains inside the engine — stuck to the walls of the oil pan and other engine parts. So you’ll remove a little more unwanted gunk when you drain out warm oil.

Can you let oil drain overnight?

Probably unnecessary to leave it out overnight but shouldn’t hurt anything. I don’t suppose a foreign object would enter the pan and contaminate it while open to atmosphere. A small quantity of dirty engine oil will probably still remain trapped in the engine even after an overnight drain.

An oil drain plug can fall out 2 months later; just like a spark plug can blow out 2 months later, an improperly tightened alternator mounting bolt coming loose, or whatever else fits the scenario. What the OP needs to do is provide the info about the last outfit to change the oil.

Can a loose oil plug hold the oil?

A loose oil plug will hold the oil pretty well – until that last thread lets loose and the plug comes out entirely. Then 4-5 quarts gushes out and it’s pretty much all over after that. Might a loose plug drip a little oil? Sure. Mine actually does drip b/c its rubber sealing cap is shot and I haven’t gotten a new one.
