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.

Hot baby, no matter the make/model vehicle..... I will run the vehicle for a few minutes after getting it into the oil change position "operating temp"

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!

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

"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.

Just use an insulated total body condom to protect you from the hot oil and you should be fine.

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.

Thats the best way to do this as that gets all of the available oil out of the system while holding maximum contaminants in suspension for removal.

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

Double glove for slightly more thermal protection.
