best compromise is to drain while fully hot (just use an insulated rubber glove to pull the drain plugs) and then let it cool most of the way down before doing the filters. I typically drain when I get home from work, then have dinner and do some other things and then go out and finish the change.

I tried using the mightyMite for brake bleeding in the past. The thought of draining 12 qts of oil with that pump is scary. Hand would get pretty strong though! That maybe useful to some.

I do not recall if I changed the oil hot or not. My normal practice is to change oil after the car has been run at to operating temp, then waiting 20-30 minutes - sure I followed that practice. I do not remember that I really had any issues with the oil being too hot and causing much trouble. I did remove the oil return line, and based on the amount of oil I added back, got at least an extra 1/2 qt out.
I remember the hardest part of changing the oil was locating the small engine filter!

Warm is plenty good enough. Hot is too hot; you'll burn your hands on the oil and the engine components while working under there. There's not enough oil in the oil cooler lines and oil cooler to make any difference in the health of your engine, provided you change the oil at least once a year or every 5k or so, whichever happens first. Warm is good enough.

"Warm" is how I've done it for yeeeaars, over many cars, especially the 993, and for the simplest reason: I don't like getting burned by hot parts or scalded by hot oil. Simple. As for the engine's health? ....puhlease!! I'm sure it will fare much better with an oil change even stone cold than I would getting burned.

Ahhh, a voice of reason (only because I agree
).

I've burned, cut, banged and bruised myself so many times over the years a couple more times isn't going to make a difference. Keep band-aids in the garage because of it too. Do use the disposable blue Nitrol (sp ?) gloves when doing oil changes though.

We use nitrile gloves to protect ones hands.

You are soooo right ...what the heck was I thinking!!!

FWIW, disposable gloves (a la Costco) are the norm for any/every job I do that will incur muck. I gave up on GoJo and Lava long ago ...not getting dirty is so much easier than cleaning it off
