Ok here is my .02, There are other reasons to use the drainplug in the pan (at least for me) I use this as an oportunity to inspect the suspension, rotate the tires, and anything else that is different or unsual from the last time I was underneath the car. If you never get under to change the oil when would you get under it to check these things(when they start making noise?) I have the luxury of an inground lift though
