Its all about the vw factor.

If you shut it down hot, how long do you wait to pull the plug?

If you drain it cold, you get all the rewards of all the heat thinning the oil, gravity draining and time as well.

I will break the filter loose and the plug while hot and pull the plug when cool, dump 1/2 qt in the top to flush the pan a bit and thats about all I can do.

If its a real busy time in my life, it just dont matter and the fact is I still changed the oil.

But really anyway one does it, is it really going to matter in the end?
