Problem removing drain plug: Was in a hurry and did not warm up the engine before trying to remove the drain plug. Could not remove it. Have been changing oil for years and always torque to speck. Rounded off the plug. Used extractor, but could not budge. Left for 2 hour drive, returned and while engine still hot, tried to see if I could remove it. While tapping on the extractor, the plug turned. Lesson: engine must be warm (HOT) to remove the drain plug.
