I know there's no right answer, but I'm wonder what you guys do.
I remember when I'd collect samples to send to Blackstone, their recommendation was to drive at least 20 miles before collecting a sample. I've got a one-way commute over 40 miles, so my preferred time to do an oil change was a bit after I got home from work. However, my wife isn't too happy about it an asks why do I need to do it "right now". So sometimes I'm stuck doing it on the weekends before the rest of the family is up. I'll probably warm it up for 4 miles, although we've got hills around here and I'll do some nice hill climbs, which should warm it up well.
I've heard all sorts of recommendations, including changing the oil with a cold engine to reduce the amount of mess. I've never done a cold oil change, although back when I did an extended oil change on a relatively low mileage car, I'd change the filter every 3 months when it was cold.
