A 5/8 OD plastic tube inserted very easily and snuggly into only the larger top inch and a half or so of dipstick tube allows entire diameter of dipstick tube to carry oil from lowest point in pan as it was designed to do. My fabric-embedded, clear plastic tube does not collapse carrying hot oil, though an earlier, cheaper one without fabric did. You don't need to shove the evacuation tube into the pan.
