In what manual did you see the statement to let the oil drain for 12 hours? I have not seen this anywhere. Draining the pan and changing the filter only changes 8 1/2 quarts out of a total of 12 since the oil cooler and lines are not drained. To me draining for 12 hours is pointless since 3 1/2 quarts of oil are left in the oil cooler and lines. I pull the plug to let the oil drain, change the filter while the oil is draining, and put the plug back in when there are a couple of seconds between drips. The factory torque value for the drain plug is pretty high and I've found you need to use a 6 point socket when removing the plug to keep from damaging the hex on the drain plug if you tighten the plug to the factory torque.
