Hmm good question. I am not sure why you are pretty concerned unless you haven't changed oil before. i never gave it a thought to the actual torque settings for the drain plugs. Of all the years changing my own oil in various machinery (IE cars, trucks, small engines, my own BX24 etc...) i have learned to go by the feel. you never want to over tighten those bolts. i just tighten them till it stops with light pressure and then give it a little ommph tightening so it would seal against the drain plug but easy to remove next time and not ruin the threads.
