i know this is an old thread but has anyone tried these quick drain plugs? saw them on a youtube video and it seemed interesting. the qd6000 does have a 3/8 drain plug for sure right? mine is basically stripped i was going to change my oil but im waiting on an extractor becasue ut stripped figure this might be a good alternative
