hot and often has been the old information to go off of... Hot is important - for UOA, it is usually recommended to do it no more than 1/2 hr after a hot shutdown.

I guess I'm the oddball but I usually change it cold. The night before I'd park the car in a way so it's ready to get worked on in the morning.

I have always changed my oil hot, but this last go around I didn't and to make it double bad I moved the cars to the back pad without warming them up. Fuel was through the roof!!

Hot, it will flow better and suspend more particles. Put in a Fumoto drain valve, and you do not have to worry about oil splashing or burning you.

I change it when hot, or at least warmed up. But to be honest, I'm not sure I understand the rationale of it. It seems to me that the objective is to drain the maximum amount of oil. Wouldn't that be after the oil has been allowed to settle for the longest period of time ... that is, cold? Given that a cold engine has most (all?) of its oil in the oil pan, why wouldn't draining it cold make sense? I'm serious ... I've always wondered about that.
