On any engine, oil that's in oil galleries will eventually drain back down. There's no magic number of minutes, it's going to depend on the oil, the temperature of said oil and other factors.When I do my oil I always drive home and then park it . Leave it sit for several hours. Supposedly after 35min. The oil that is up in the oil cooler will drain back on its own.
There will always be oil that will not make it back down as well, trapped in oil galleries that don't run downhill into the pan. You can take apart an engine after a week, and still leave a mess of oil all over the floor if you don't prepare for it.
I don't know where that magic 35 minutes comes from - but I can imagine.......................
Me - change it when hot. More oil is going to run out faster. I will leave it open longer than many so that probably adds up to 35 minutes LOL
