Is it a good idea to use WD-40 in engine oil?

I'm honestly just curious about if WD-40 would help get the water out if you blow a head gasket when you do an oil change

Gas engine running on WD-40:  Granted it’s lawnmower engine, but still interesting experiment:

no.

nope.

 

water is heavier than oil though, so it should end up in the pan. I would just run the engine for a little bit, and then drain out some of the oil.
