I voted hot, because that's the best way to get the most of the old oil and crap out, and I do it hot 98% of the time. I don't obsess over it if I need to change it cold though. I just let it drip longer.

you always want to change motor oil right after you shut it off, and is still hot. otherwise all the junk in the oil won't drain out, it'll be sitting in the bottom of the sump instead of draining out with the oil.

It doesn't really matter unless you've got an oil cooler with a thermostat. The oil flows out quicker when it's warm, that's about it. You'll still have oil with impurities suspended in it in the motor whether it's hot, warm, or cold.
Change your oil regularly with quality oil. If you're worried about impurities, get a UOA done with both a hot and a cold drain. There's no difference between them.

Not enough to make a difference, unless you've got sumping issues.

I will take quick ride long enough to get the engine hot.Then I let it sit for about 20 min.
The engine will still be hot enough for the oil to drian out good.

I voted hot for thats how I was taught by my uncle who was a mechanic for 41 yrs for Chevy before he died. I always drain my scoot oil through a paint strainer while draining it, just to see what is coming out.
Thats what gave me a heads up on my tensioners. Not much, just enought to make me go "humgh", andmaybe I need to break into this and see what we have here!!
